Basic Model Build Tutorial
Welcome!
Basic Model Building
The goal of the software is to remove the time consuming process of model building so
that you can spend more time analyzing your results and gain a better understanding of
your supply chain.
This tutorial will walk through the basic model building steps applicable in every model.
Before you begin:
Install the software
Register for your license(s)
Ensure that your license is listed in the same directory as the Supply Chain Guru
program files
Open the software and add a new model
There are six required tables when building any model in Supply Chain Guru:
Products Table
Sites Table
7
Printed Documentation
Demand Table
Sourcing Policies Table
Transportation Policies Table
Inventory Policies Table
These completed tables successfully capture both the physical and behavioral elements
of any supply chain system. The interaction of these tables with the optimization and
simulation engines results in data output used in analysis.

Model Overview
In the basic model we are going to build, there is one Customer Site which places a
demand order for a Widget from the Manufacturing Plant. The Manufacturer makes this
product and ships it to the customer.
The basic model represents the following characteristics of the supply chain:
Physical Elements
Products
Widget
Sites
Facility Site
Manufacturing Plant (MFG)
Location: Barcelona, Spain
Produces both products
Customer Site
Customer_1 (CZ_1)

Basic Model Build Tutorial
Basic Model Products
In a supply chain, the Products include raw materials and finished goods which pass
from one site node to another within the network.
To begin a simple model, we must first enter the information on the Product in the
supply chain.
Create the Product Table
Enter the following:
Name: Widget
Value: 1
Price: 2
Weight: 1
Cubic: 1
Type: Discrete (Default)

Basic Model Build Tutorial
Basic Model Demand
The Demand table plays an integral role in the Supply Chain. While only the sites
designated as a "Customer" in the Sites Table can place an initial order for the product,
the subsequent site nodes in the chain seek to improve customer service by meeting
the due dates of demanded shipments. In turn, the Customer Demand fulfilment
generates revenue and increases a supply chain's profit.
Create a Demand Table
Enter the following:
Product Name: Widget
Site Name: CZ_1
Quantity: 100
Order Time: 01/01/2008
Occurrences: 52
Time Between Orders: 1WK
Save and Close the table
Back to Sites or Continue to Sourcing Policies
15
Printed Documentation
Basic Model Sourcing Policies
Now that we have modeled the physical elements of our Supply Chain, we will begin to
build the tables which depict the interaction of the sites and products.
We begin by creating the Sourcing Policies Table. In the software, the sourcing policies
depict from which sites another site can receive products. If the site creates or
manufactures that product, then it is listed a "Make" policy with no site listed as the
source site. There must always be at least one site with a "Make" policy in every model.
Create the Sourcing Policies Table
Add the following two records:
Site Name: MFG
Product Name: Widget
Sourcing Policy: Make
Source Name: (Leave blank)
Site Name: CZ_1
Product Name: Widget
Sourcing Policy: Single Source
Source Name: MFG
Save and close the table

Basic Model Transportation Policies
Now that we have determined which sites can ship products to another site, we must
set designate how the product is going to go from the Source to the Destination.
In the software, the transportation policies describe the possible methods for shipments
between sites, which are designed through the sourcing policies table. The
transportation policies indicate the methods, or Modes, available on that source site and
destination site lane.
Create the Transportation Policies Table
Add the following:
Source Site: MFG
Destination Site: CZ_1
Mode: 1 (Default)
Policy: LTL (Default)

Basic Model Build Tutorial
Basic Model Inventory Policies
Now that we have products shipping between sites, we must determine how each
Facility Site is going to manage the stock of products to meet the customer demand.
A facility site may hold inventories of raw materials, parts, or finished products for many
reasons including creating buffers against the uncertainty of demand and supply,
utilizing transportation cost savings associated with higher volumes of shipped goods,
building a seasonal reserve of goods, or reducing production costs by using economies
of scale with batch production. The Inventory Policies Table depicts these methods and
approaches for inventory management.
Create an inventory policy table
Add the following:
Site Name: MFG
Product Name: Widget
Inventory Policy: s,S
Reorder Pt: 1000

Auto Generating Inventory Policies
Setting up inventory policies for each product and site can be a repetitive job. To make
inventory policies easier to create, SC Guru allows you to automatically generate
inventory policies. Auto generating policies creates a new inventory policy record as
required using data entered into the Sourcing Policies table.
The Auto Generate Inventory Policies tool fills the inventory data tables with default
values. The Inventory Policy is defaulted to Demand Flow. You should review the data
table fields to make sure the policies agree with your supply chain model.

Layout Map
Layout Map
The Layout Map is a map of the world which appears in the main window and provides
a layout of your supply chain as your model grows. When you enter your supply chain’s
physical sites in the Sites Data Input table, markers (like the yellow circle and green
square) will indicate their locations on the map, at the latitude and longitude coordinates
of your site. When you enter sourcing policies, the relationship between sites is
indicated on the sourcing layer by connected lines. In this way, the Layout map
provides a graphical representation of your supply chain. When you run a simulation,
your supply chain activities are animated on the map.
The Layout remains open beneath the other active windows unless you close it. You
can always switch to this graphical view of your supply chain by clicking the Show

Fixed Cost Fields
The Fixed Startup <Cap,Cost> and Fixed Operating <Cap,Cost> fields can be filled
using the Field Guru dialog. The unit of measure for shipment capacity is set in the
Capacity Basis field - quantity, weight, or cubic. The cost is the fixed startup or
operating cost for a certain capacity.
The Fixed Startup <Cap,Cost> and Fixed Operating <Cap,Cost> fields are step, or
incremental, functions. This means that as throughput levels increase, the cost jumps
only at discrete points. For example, initial fixed operating costs before any product is
shipped may be $50,000 (<0, 50000>). Then, it may cost $75,000 after the shipment
capacity of 1000 units (<1000, 75000>).
Enter <Cap,Cost> Data
1. Click the Field Guru
in-cell button. The Field Guru - Fixed Startup dialog appears.

throughput capacity. The second number indicates operating cost.
For example, an entry of <0, 1000000> <500000, 2000000> <15000000, INF> indicates
that there is an initial operation cost of $1,000,000 before any product is shipped. In
order to get capacity to more than 500,000, the operating cost increases to $2,000,000.
The maximum capacity is 15,000,000 as indicated with a cost of infinite (INF). If the
cost is INF for a certain capacity level, that capacity is considered as a hard constraint.

Avg Unit Cost
This field specifies the average cost per unit for sourcing to be used in the network
optimization for this time period.
Alternatively, instead of having a simple constant cost, you can set up a cost schedule,
using quantity break points and different costs with the Guru bracketed format, such as
<0,1.50> <5000, 1.25> <10000, 1.00>. In this example, the sourcing cost per unit is
1.50 for units 0 through to 5,000, 1.25 for units 5,000 through to 10,000, and 1.00 for
units 10,000 and up. For an order consisting of 20,000 units, the total cost will be:
(5,000-0)*1.50 + (10,000-5,000)*1.25 + (20,000-10,000)*1.00 = 23,750.
Note: Simulation and optimization handle costs differently! Simulation costs are
calculated on a per order basis for each individual order (using the Sourcing Cost
value). Optimization costs are calculated using the aggregate flow quantity for the
entire time horizon (using the Avg Unit Cost value). Thus, when using quantity-cost
break points, you will use different break points for simulation and optimization.

Avg Cost
In this field, enter the change in the Average Cost during this time period. The Avg Cost
field is related to the Cost Basis field, which is specified on the single-time period
transportation policies table. The value entered in the Avg Cost field is the
transportation cost per Cost Basis unit. For example, if Cost Basis is Qty, Avg Cost
should be the cost to ship 1 unit. If Cost Basis is Distance, the Avg Cost should be the
cost of shipping 1 unit of distance. Avg Cost has an Average Cost Field Guru
associated with it.
Flow Reqt
In this number field, enter the amount of this product required for shipment over the

In this drop down menu, select the time period in which the changes in the routing will
occur.
Process Name
In this text field, enter a descriptive name for the process you are specifying for this
period.
Process Step Name
In this text field, enter a descriptive name for this particular step of the process that you
are specifying.
Next Process Step
In this text field, choose the next step of the process. When the process is complete,
choose None or leave the Next Process Step field blank.
Cost Per Unit
In this number field, enter the cost of production for each unit at this work center during
this period. Each step in a production process can have a different cost. As the
production order goes through each routing step, costs accumulate until the order is
complete. The total cost of the order is then added to the site production cost statistics.
Setup Cost
In this number field, specify the initial costs for implementing the Work Center to
process a specified product during this period. Setup Costs are applied for each batch,
i.e. the setup costs are calculated based upon the lot size and the number of units
processed.
Yield
In this number field, enter the loss factor due to this work center during this period. For
example, if 10% of the material that was input to a cutting production step (making
skewed edges straight) is lost due to the cutting, the yield factor is equal to 0.9: 90% of
the material that was inputted is outputted after this production step.
Demand (from a customer/facility or input of the next work center) determines the net
production, that is the amount that needs to be output of a certain work center. The
input needed at a work center (gross production) is calculated from the demand and the
yield value.

Fixed Startup <Cap/Cost> (Optimization only)
In this field, enter a function that defines the relationship between startup capacities and
startup cost. The function is specified by a series of coordinates. The first number in
the coordinate indicates shipment capacity. The second number indicates the startup
cost.
For example, an entry of <0, 1000000> <500000, 2000000> <750000, 2500000>
indicates that before any products can be shipped, an initial expenditure of $1,000,000
must be invested. In order to get capacity to more than 500,000, an initial expenditure
of $2,000,000 is needed. For capacity to be greater than 750,000, an initial expenditure
of $2,500,000 is required.
Fixed Startup Costs are always applied to the optimization horizon.
Fixed Operating <Cap/Cost>
In this field, enter a function that defines the relationship between operating capacity
and operating costs for this time period. The function is specified by a series of
coordinates. The first number in the coordinate indicates production capacity. The
second number indicates operating cost.
For example, an entry of <0,1000000><500000, 2000000> <15000000,INF> indicates
that there is an initial operation cost of $1,000,000 before any product is produced. In
order to get capacity to more than 500,000, the operating cost increases to $2,000,000.
The maximum capacity is 15,000,000 as indicated with a cost of infinite (INF). If the
cost is INF for a certain capacity level, that capacity is considered as a hard constraint.

Value
In this number field, enter a monetary value for each unit. The Value field is used to
calculate the inventory investment and inventory holding costs. It is incorporated in the
following formula:
Inv holding cost = Avg Inv * Product value * Holding Cost Percentage * Length of
Time in Inventory
Price
In this number field, enter the revenue generated from the sale of a single unit of this
product. The product price is used to calculate revenue statistics.
Each time a customer order for this product is filled, it is registered as a sale. Revenue
is determined by the number of units sold multiplied by the price of the product. In case
a Unit Price is specified on the Demand table, in that case the Price in the Products
table is over-ridden. When no Unit Price is specified on the Demand table, the Price
field on the Product table is the default for Revenue calculations.
Weight
In this number field, enter the weight for a single unit of your product. Weight is used to
calculate truck fill levels and weight-based transportation costs. You can use the
English or metric system, just be consistent throughout your model. Do not specify a
unit of measure in this field (e.g., 10 ton), just the numeric value.
Cubic
In this number field, enter the cubic volume for each unit of product. Cubic is used to
calculate truck fill levels and cubic-based transportation costs. It is also used to
calculate site space utilization statistics. You can use the English or metric system, just
be consistent throughout your model. Do not enter a unit of measure, just the numeric
value.
Type
The type field enables you to define the allowable quantity values for this product.
Many products can only take on integer values, such as 1, 2, 3, etc. For example, if
you are modeling a product such as "airplane", it wouldn't make sense to have ½ of an

airplane! For such products, set the Type field to be "discrete". For products that can
have fractional values, such as liquid chemicals, or dry-mix concrete, set the Type to be
"continuous". If the field is left empty, then it is assumed to be continuous.
Status
The status field allows you to specify whether a product is included or excluded from a
model simulation or optimization.
If the field is left blank, the product is assumed to be included.
If the product status is set to "Exclude", none of the policies that use this product
will be built, including inventory, sourcing, product-specific transportation policies,

In this field, enter a function that defines the relationship between startup capacities and
startup cost. The function is specified by a series of coordinates. The first number in
the coordinate indicates shipment capacity. The second number indicates the startup
cost.
For example, an entry of <0, 1000000> <500000, 2000000> <750000, 2500000>
indicates that before any products can be shipped, an initial expenditure of $1,000,000
must be invested. In order to get capacity to more than 500,000, an initial expenditure
of $2,000,000 is needed. For capacity to be greater than 750,000, an initial expenditure
of $2,500,000 is required.
Fixed Startup Costs are always applied to the optimization horizon.
Fixed Operating <Cap,Cost> (Optimization only)
In this field, enter a function that defines the relationship between operating capacity
and operating costs. The function is specified by a series of coordinates. The first
number in the coordinate indicates shipment capacity. The second number indicates
operating cost.
For example, an entry of <0, 1000000> <500000, 2000000> <15000000, INF> indicates
that there is an initial operation cost of $1,000,000 before any product is shipped. In
order to get capacity to more than 500,000, the operating cost increases to $2,000,000.
The maximum capacity is 15,000,000 as indicated with a cost of infinite (INF). If the
100

Apply Fixed <Cap, Cost> to Horizon (Optimization Only)
In this field, select Yes or No from the drop down menu. When it is set to Yes, the
specified Cost and Capacity structure for the Fixed Operating Costs is applied over the
total length of the optimization. When periods are specified in the Multi-Time Periods
Table, and this field is set to No, the Cost and Capacity structure will be applied to each
individual period.
Fixed CO2 <Cap, CO2>
The fixed CO2 field allows a user to specify levels of CO2 output based on the sites
throughput. This can be entered as a step function similar to site fixed operating costs.
Therefore, entering <0, 5000000><100000, 10000000> would represent 5000000 kg of
CO2 output from opening the site. If the site has a throughput of over 100000 then the
CO2 output would be 10000000 kg.
Expansion Only
If set to Yes, then the site cannot close after it has already opened. This prevents the
model from opening a new site for excess capacity in one period, then closing it for the
next.
Closing Cost (Optimization only)
In this number field, enter the monetary cost of shutting down operations at this site. In
an optimization, closing cost will be included if a site with the type Existing Facility is
closed.
Single Site Sourcing (Optimization only)
When this field is set to ”Yes”, the site will be required to source all products from only a

A Tip: You can select your Products and Sites from the drop-down list fields or enter
the first few letters of the product or site and the software will find the first match from
the drop-down list.
Product Name
In this text field, enter the product that is being demanded.
Quantity
This field supports both numbers and distributions. If a probability distribution is
specified, the quantity will be randomly selected each time the demand requirement
occurs in simulation. For optimization, the mean of the distribution will be used as the
demand amount. Use the field Guru for help inputting the correct distribution.
Order Time
The order time is the time the order is placed if only one Occurrence is scheduled (see
occurrences below). If more than one occurrence is scheduled, then the Order time
field becomes the time of the first Order, then the "Time Between Orders" field dictates
the next time an order occurs.
Optimization is only currently only supports orders with one Occurrence.
Order time has a Field Guru associated with it that allows you to enter probability factors
or dates for order time.
Due Date
This number/distribution field is used to specify when an order must be filled.
In a simulation, the order cycle time is the period of time between the occurrence of the
order (Order Time) and the time the order was satisfied (arrives at the customer and
fulfills demand). When the order arrives at the customer, the current time is checked
and compared to the Due Date. This is how the software determines if a shipment is on
time or late.
In optimization, the Due Date field can be used as a constraint. If you populate the Due
Date field for records in an optimization, and then check "Classify Demand By Due
103

Date" in Model Options (F3), it will act as a constraint for flow on the customer flow (the
last echelon of the model). The demand with due date constraints will not be able to
use any mode or lane that is longer than the specified Due Date. For this feature,
specified the actual date due (ie 1/1/2010) is not supported.
Due Date has a Field Guru associated with it, see Due Date Field Guru for details.
Note: The default Due Date unit is DAY. If you do not enter a time unit, the software
assumes the Due Date is measured in days.
Note: If Due Date is left Blank, the software assumes the order is due immediately when
demand occurs.
For example:
If you want the Due Date to occur:

Data Tables
Note: If you are defining demand by using a pattern, you do not need to enter the
Occurrences or Time Between Orders. The pattern specifies this for you. The software
will ignore data entered in these fields.
Time Between Orders
The Occurrences field is used to specify the time between multiple orders. In this
number/time/distribution, enter how much time must pass between each recurring
demand. For example, Time Between Orders can be 24 HR, meaning that orders recur
every 24 hours for as many occurrences specified.
Note: You must enter data in this field if the Occurrences are greater than 1. If you do
not enter Time Between Orders and demand recurs, the software will assume that this
demand happens once a day.
Time Between Orders examples are in the following table.
If you want:
Enter
Recurring daily demand
Time Between Orders: 1 DAY or leave blank
Occurrences: INF
Randomly occurring demand
according to a triangular distribution
Time Between Orders: T(1,3,4) DAY
Occurrences: INF
Note: If you are defining demand by using a pattern, you do not need to enter a data in
the Occurrences or Time Between Orders fields. The pattern specifies this for you.
Pattern (Simulation Only)
This text field allows patterns of demand to be distributed over periods of time. Pattern
represents a predefined set of occurrences, instead of a single occurrence.
Note: If you are defining demand by using the Occurrences and Time Between Orders,
you do not need to enter data in the Pattern field.
Pattern is directly related to Quantity. The pattern you select will take the total
aggregate quantity stated in the Quantity field and spread it out, as evenly as possible,
over the desired time frame. For example, If Quantity is less than the number of
occurrences in the Pattern, the software adds additional time between the recurring
demand and the order. If Quantity is greater than the number of occurrences in the
Pattern, the software evenly distributes the quantity over the entire time amount.

field for this product in the Products Table.
When the Unit Weight field is left blank, the Weight field in the Products Table will be
used to calculate Shipment Weight. Currently this Unit Value will only apply to the first
echelon above the customer.
Unit Cubic
A customer specific cubic volume can be defined for one unit of the product being
demanded in this number field. This number will then be used to calculate shipment
cubic volume at this site by demanding this specific product cubic volume instead of the
value listed in the Cubic field of this product on the Products Table.

Sourcing Policies
Site
In this text field, enter the site for which the sourcing policy is being applied to.
Product Name
In this text field, enter the product for which the sourcing policy is being applied to.
Sourcing Policy
In this text field, choose a sourcing policy. See Sourcing Policies to learn about the
different kinds of Sourcing Policies.
Policy Parameter
This number field is used in conjunction with the Multiple Sources and Single Source
sourcing policies.
For the Multiple Sources (Order of Preference), Multiple Sources (Allocate by
Preference), and Make (First Available) sourcing policies, assign a preference to each
source site. For example, you have two possible sources for your Lemonade Lemonade Supplier1 and Lemonade Supplier2. Lemonade Supplier1 is your most
preferred source, so you would assign a Policy Parameter of 1. For Lemonade
Supplier2, you would enter 2 in the Policy Parameter field because it is your second
choice for supply.
For Multiple Sources (Probability), and Make (Select by Probability) assign a probability
to each source site. For example, you have two possible sources for your Lemonade Lemonade Supplier1 and Lemonade Supplier2. Lemonade Supplier1 has a probability
of filling replenishment orders of 75. Lemonade Supplier2 has a probability of filling
replenishment orders of 25. This means that, on average, Lemonade Supplier1 will fill
75% of the replenishment orders and Lemonade Supplier2 will fill 25% of the
replenishment orders.
Note: You enter the probability of .75 (75%) as 75 in the Policy Parameter field. Total
probabilities must add up to 100.
Source Name
In this list field, choose a site that can fill this replenishment order, or a work center that
has a process record for this product.
109
Printed Documentation
Note: If using the Make souring policy, this field can be left blank.
BOM Name
In this text field, you choose the BOM Name for the end product you are making.
This should be used when defining a ’Make’ sourcing policy. If the end product defined
in this ’Make’ sourcing policy is made up of component products from further upstream
in the model, a Bill of Materials data table can be defined along with this ’Make’ sourcing
policy.
The Make policy tells the software that this end product is being made at that particular
site, while the BOM Name tells the software to look at the relevant BOM for the amount
of component product(s) that is required to make that particular end product.
Any subsequent order for the end product with a BOM will trigger an inventory check for
its component products. The corresponding inventory policy for the component
product(s) at that site will then decide if a replenishment order should be placed for the
component product(s).
Note: If using the make policy, you should have listed all components of your product in
the Bill of Materials data table.
Process
In this field, select the process name that the product has to go through while at this
particular site. This process can be chosen from the drop-down list in this field.
Processes have to be specified on the Processes Table, and should have an
associated Workcenter(s).
Sourcing Cost (Simulation only)
Enter the unit cost of production if it is made at this site.
Alternatively, instead of having a simple constant cost, you can set up a cost schedule,
using quantity break points and different costs, with the Guru bracketed format, such as
<0, 1.50> <50, 1.25> <100, 1.00>. In this example, the sourcing cost per unit is 1.50 if
the order quantity is between 0 and 50, 1.25 for quantities between 50 and 100, and
1.00 for quantities greater than 100.
Note: You should always make the first cost in a cost lookup function start with a
quantity of zero, such as <0, 1.50>. If you setup the first cost/qty lookup to a number
greater than zero, you will not have any cost setup for low qty numbers!
Source Lead Time
110
Data Tables
If using a Make sourcing policy, in this number/distribution field, enter the production
time per order. This is independent of the number of items in an order. For example, it
may take 5 hours to prepare a machine before items are produced.
If receiving a product from outside, enter the time it takes to issue an order. For
example, it may take 2 hours to do the paperwork for an order.
Source Lead Time Per Unit (Simulation only)
In this number/distribution field, enter the additional time it takes to produce an item in
the order. For example, each unit of lemonade may take 2 minutes to be produced. If
you do not make the product at this site, you do not have to enter data in this field.
Note: The software calculates total production time using Source Lead Time + (Source
Lead Time Per Unit X number of units in the order).
Avg Unit Cost (Optimization only)
This field specifies the average cost per unit for sourcing to be used in the network
optimization run.
Alternatively, instead of having a simple constant cost, you can set up a cost schedule,
using quantity break points and different costs with the Guru bracketed format, such as
<0,1.50> <5000, 1.25> <10000, 1.00>. In this example, the sourcing cost per unit is
1.50 for units 0 through to 5,000, 1.25 for units 5,000 through to 10,000, and 1.00 for
units 10,000 and up. For an order consisting of 20,000 units, the total cost will be:
(5,000-0)*1.50 + (10,000-5,000)*1.25 + (20,000-10,000)*1.00 = 23,750.
Note: Simulation and optimization handle costs differently! Simulation costs are
calculated on a per order basis for each individual order (using the Sourcing Cost
value). Optimization costs are calculated using the aggregate flow quantity for the
entire time horizon (using the Avg Unit Cost value). Thus, when using quantity-cost
break points, you will use different break points for simulation and optimization.
Apply Cost To Horizon
When set to Yes, the specified Avg Unit Cost will be calculated over the total length of
the optimization. When periods are specified in the Multi-Time Period Periods Table,
and this field is set to No, the Avg Unit Cost will be applied to each individual period.
This setting matters for the total costs only if the Avg Unit Cost specified is a stepwise
function. If the Avg Unit Cost is a numeric value, the total Production/Sourcing costs will
be the same whether the model is a single-time or multi-time period model.
Max Sourcing Distance (Optimization only)
111
Printed Documentation
In this number field, enter the maximum distance allowed between source and
destination sites for the product. In an optimization, the software will limit the sourcing
alternatives to those within the maximum distance radius.
Note: Entering 0 or leaving Max Sourcing Distance blank does not impose any
constraint.

Transportation Policies
Source Site
In this text field, choose the source site from which the product is to be transported.
Destination Site
In this list field, select the destination site that will receive the product.
Ship To
If the Ship To field is used in a transportation policy it means that the SourceDestination lane becomes a virtual lane. The Source does not ship directly to the
Destination, but it ships to the site specified in the Ship To field (the end destination of
the route is still the site specified in the Destination Site field). Transportation policies
for the Source - Ship To and Ship To - Destination site combinations need to exist in the
transportation policies table.
Product Name
In this text field, choose the product to be transported. Transportation Policies can be
product-specific, apply only to a set of products (using a set in the Groups Data Table),
or apply to all products on that lane if the Product Name is left blank. Specifying a
product will create a product-specific transportation policy that only affects transporting
this product from Site A to Site B. No other product will use this policy.
If you are using the aggregate or disaggregate transportation policy, you will designate
a transportation asset type as "container" in the Transportation Assets Data Table. This
container will be visible in the drop down box of the Product Name Field.
Mode
The mode is a descriptive term used to describe the transportation mode, such as
Customer_Delivery or TruckingCompany1.
Mode Rule
In this list field, choose the Mode Rule to be used for transportation policies that have
multiple modes (these have the same Source-Destination combination). The options
are explained in the table below:
Mode Rule
Example
First
The mode with the lowest Mode
number will be used.
115
Printed Documentation
First Available
Asset
The mode for which an asset
becomes available first will be used.
By Probability
The mode will be picked based on
the probability. Here the mode
number reflects this probability.
(See Mode Parameter)
On Due Date
In the simulation engine, the modes
are sorted in descending order from
Longest to shortest. The first mode
that can fulfill the order on time
(before or on the Due Date) will be
used.
On Qty
The mode will be picked based on
the size of the order (in units). One
mode with mode# 0 needs to be
specified, and other modes where
the mode# is used as the unit-break
points. If there are 2 modes, one
with mode# 0 and one with mode#
200, orders that have a size
between 0 and 200 units, will take
mode 0 and orders =>200 units, will
take mode 200.
On Weight
The mode will be picked based on
the size of the order (in weight).
Similar to On Qty.
On Cubic
The mode will be picked based on
the size of the order (in cubic).
Similar to On Qty.
Queue Only
Shipments will only be placed in a
queue, but never dispatched.
Queue Only assumes a customer
written script takes care of
scheduling shipments.
Custom
A custom script defined in the
scripts table.
Parameter
The parameter is used differently depending on the mode rule specified.

Mode Rule
Parameter use
First
Modes will be used in alphabetical
order by Mode Name.
By Probability
Enter 30, if chances are 30% that
this mode will be used. The
probabilities for the lane need to
add up to 100.
On Qty
The mode will be picked based on
the size of the order (in units).
Each mode should have a range in
which to send it (ie 0-200 =
Mode_1, 200-500 = Mode 2, 500 And above = Mode 3). Take the
first number in the range for that
mode, and place that in the mode
parameter.
On Weight
Each mode should have a range in
which to send it (ie 0-200 =
Mode_1, 200-500 = Mode 2, 500 And above = Mode 3). Take the
first number in the range for that
mode, and place that in the mode
parameter.
On Cubic
Each mode should have a range in
which to send it (ie 0-200 =
Mode_1, 200-500 = Mode 2, 500 And above = Mode 3). Take the
first number in the range for that
mode, and place that in the mode
parameter.
Queue Only
Shipments will only be placed in a
queue, but never dispatched.
Queue Only assumes a customer
written script takes care of
scheduling shipments.
Custom
A custom script defined in the
scripts table.
Review Period
117
Printed Documentation
In this text field, enter how often the queue at the transportation LANE is checked. If left
blank, the queue is evaluated every time a shipping item enters. If a review period is
specified items are queued, and then evaluated together. By default, all of the provided
mode rules make decisions of the aggregate contents of the queue. So for example, if
my Mode Rule was "On Weight", and I had a review period of 1 Day; then every day the
simulation would sum the weight of all the items in queue, and apply the mode rule to it.
The review period can be left blank, set to one value, or assigned a schedule as well.
See the table below for how to enter data:
If the review period is left blank, as soon as an item enters the queue, it will be
evaluated by the Mode Rule.
If the review period has a value entered in it (i.e. 12 Hour or 1 Day etc), the mode logic
will repeat fire specified by the interval in the review period. (If the review period is 12
Hour, the queue at the transportation lane will be evaluated every 12 hours).
The review period as supports a repeating schedule. The format is the same as a
single value in the review period, except a comma is placed between the single values.
An example follows:
1 Day, 3 Day, 2 Day
In the above example, a Review of the queue will occur after one day. Then the next
review will occur 3 Days after the first review. Then the third review will occur 2 Days
after the second. When the schedule completes, it repeats itself.
Review periods themselves are dependent on the start time of simulation. So if the start
time set in the Model Options is 12:00 AM 1/1/2010, and the review period is set to 24
HR. The queue at the lane will be reviewed everyday at 12:00 AM. An offset can be
entered in front of the review period to change the time the model will start reviewing.
The offset will only be incurred once.
For example, if we would like to Review the queue everyday at 4 pm, and our simulation
starts at 12 AM; an offset of 16 hours can be entered to shift the review time to 4 pm.
Then, if we have 24 hour review period, it will check every 24 hours from the time to
which it was offset. The format for the offset is as follows: < "Time" >
For the a 16 hour offset, with a daily review you would enter: <16 HR>, 24 HR
Transportation Policy
118
Data Tables
In this text field, choose a transportation policy. See Transportation Policies for more
details.
Shipment Period (Simulation only for the Periodic Shipment Only)
In this text field, enter the schedule for a Periodic (i.e. scheduled shipment).
The Shipment period as supports a repeating schedule. The format is the same as a
single value in the review period, except a comma is placed between the single values.
An example follows:
1 Day, 3 Day, 2 Day
In the above example, a Shipment will occur after one day. Then the next Shipment will
occur 3 Days after the first Shipment. Then the third Shipment will occur 2 Days after
the second. When the schedule completes, it repeats itself.
Shipment schedules themselves are dependent on the start time of simulation. So if the
start time set in the Model Options is 12:00 AM 1/1/2010, and the Shipment period is set
to 24 HR. The Shipments will depart everyday at 12:00 AM. An offset can be entered
in front of the Shipment schedule to change the time the shipments depart. The offset
will only be incurred once.
For example, if we would like to ship everyday at 4 pm, and our simulation starts at 12
AM; an offset of 16 hours can be entered to shift the review time to 4 pm. Then, if we
have 24 hour shipment schedule, it will check every 24 hours from the time to which it
was offset. The format for the offset is as follows: < "Time" >
For the a 16 hour offset, with a daily shipment you would enter: <16 HR>, 24 HR
Transport Time
In this number/distribution field, enter the length of time that a shipment takes to travel
from the Source site to Destination site. This field can accept a properly formatted
probability distribution or simple time units. The default time unit is Day. If a probability
distribution is used, the distribution is sampled and a different transport time is
determined for each shipment. Transport Time is not a required field for any
transportation policy. If no time is entered, a default will be calculated from Source site
to Destination site based on the latitude and longitude of each site, taking the speed of
the transportation asset into account. When no asset is used in the transportation
policy, the Default Transport Speed specified on the Model Options (F3 or Tools ->
Model Options) will be used.
Asset Name
119
Printed Documentation
In this text field, choose the asset that will transport your product. This field is
necessary when using the Full TL, and Pooled policies and optional for others. You can
get more information on Assets in the Transportation Asset Table.
Cost (Simulation only)
This is the cost of transportation in the simulation. The Cost Rate field is used in
conjunction with the Cost Basis field. There are four ways in which to input costs for
this field:
Enter in a Single Number
The single value will be interpreted differently based on the Cost Basis.
Enter in a step function
A step function can be entered with assistance from the Cost field guru
Use a Dynamic Rate table (via the Input Pipes table)
1. Write a custom script to calculate costs (using Scripts)
Average Cost (Optimization only)
The Average Cost field is related to the Cost Basis field. The value entered in the
Average Cost field is the transportation cost per Cost Basis unit. For example, if Cost
Basis is Qty, Average Cost should be the cost to ship 1 unit. If Cost Basis is Distance,
the Average Cost should be the cost of shipping 1 unit of distance. Average Cost Rate
is only used by optimization and has an Average Cost Field Guru associated with it.
Simulation uses Cost Rate to calculate transportation costs.
Cost Basis
In this text field, choose the formula for calculating the total transportation cost for a
shipment from Source site to Destination site. The default Cost Basis is Qty. Actual
shipment Cost is calculated as follows:
Cost Basis
Shipment Cost
Weight
Product Weight x Order Quantity x Cost Rate field value.
Quantity
Order Quantity x Cost Rate field value.
Cubic
Product Cubic x Order Quantity x Cost Rate field value.
Distance
Distance x Cost Rate field value.
Fixed
Cost Rate field value.
Weight-Distance
Product Weight x Order Quantity x Distance x Cost Rate
120
Data Tables
field.
Qty-Distance
Order Quantity x Distance x Cost Rate field value.
Cubic-Distance
Product Cubic x Order Quantity x Distance x Cost Rate
field value.
Shipment Weight
In this field, enter the average weight of your shipments. This field is only used for
optimization models when the Cost Basis is set to Distance or Fixed. It is used to
determine how many trips are needed to satisfy the flow of product for the respective
mode.
For example, if the average shipment weight for a mode is 50 and 100 units of weight
flow on the mode, there are 2 required trips. If the Cost Basis is Fixed and the Average
Cost is 200, then the transportation cost for this mode is 400. Similarly, if the Cost
Basis is Distance, the transportation cost for this mode would be the Average Cost (200
from the previous example) times the distance in miles (found in the Distance field)
times the number of trips (2).
Distance
In this number field, enter the distance between the source and destination. The
software will estimate the distance for your sites (using latitude and longitude in the
Sites table), if you click the in-cell button.
Duty Rate
In this field enter a duty rate to represent the taxes and tariffs that will be levied for each
shipment on this lane. The actual duty cost is calculated by multiplying the duty rate by
the shipment’s total value (product value multiplied by shipment quantity.)
Discount Rate (Simulation only)
In this number field, enter the discount factor negotiated with the transportation
company. This rate is multiplied by the cost to determine the actual cost in Simulation.
The default value is 1.0 (no discount). For example, if the negotiated discount is 45%,
enter a discount rate of 0.55. If the cost is $100, the software will multiply 0.55 by 100
to get an actual rate of $55.
Min Charge (Simulation only)
In this field enter any minimum rate negotiated with the transportation company.
Minimum rates override costs if the cost is less than the minimum charge.

Load Cost
Cost to load order.
Unload Cost
Cost per to unload order.
Unit Load Cost
Cost to load one unit of product.
Unit Unload Cost

Require Return Trip (Simulation Only)
If an asset is used in the transportation policy, this field specifies if the asset must
require a return trip.
Return Trip Time
If an asset requires a return trip, this is the time it takes for asset to travel from final
destination to initial start point.
Return Trip Cost
If an asset is used in the transportation policy, this field specifies the cost for the asset
to return to the Source Site.
Load Time
Time allowed for the product to be prepared for dispatch.
Unload Time
Time allowed for the product to be unloaded.
Load Unit Time
Time-unit used for the load time value.
Unload Unit Time
Time-unit used for the unload time value.

Data Tables
In this text field, choose a graphic to represent the shipment from source site to
destination site. The graphic will be used in the animation of the simulation of the
supply chain.
CO2
In this field, set the CO2 emissions for this transportation mode. There is a Field Guru
associated with the CO2 emissions field. CO2 basis is a weight-distance, therefore the
CO2 emission quantity is set at kg per weight unit, per unit of distance.
For example, of .04 is entered, then this is .04 kg of CO2 per one unit of weight of
product moved over one mile by this transportation mode. See CO2 Field Guru.
Apply Cost To Horizon (Optimization Only)
When set to Yes, the specified Average Cost will be calculated over the total length of
the optimization. When periods are specified in the Multi-Time Period Periods Table,
and this field is set to No, the Average Cost will be applied to each individual period.
This setting applies to the total costs only if the Average Cost specified is a stepwise
function. If the Average Cost is a numeric value, the total transportation costs will be
the same whether the model is a single-time or multi-time period model.
Flow Reqt (Optimization only)
In this number field, enter the amount of this product required for shipment over the
transportation lane. Its use is determined by three other flow requirement fields listed
below; Flow Requirement Type, Flow Requirement Basis and Flow Requirement Period.
Flow refers to the amount of product moved by this transportation policy in a given time
period. Flow Requirement fields are only used in an optimization; a simulation run will
ignore these four fields. An optimization will use flow requirements as constraints.
Flow Reqt Type (Optimization only)
In this text field, choose the flow requirement type - conditional minimum, minimum,
maximum, or fixed. This defines how the Flow Requirement is used in an optimization.
The conditional minimum flow establishes that, in order to use this transportation lane
for any shipments, a minimum flow is necessary. Essentially this constraint is similar to
saying the flow can be 0 or higher than the minimum.
Flow Reqt Basis (Optimization only)
In this text field, choose the flow requirement basis - Quantity, Weight or Cubic. This
defines the units of measurement for the flow requirement.
123
Printed Documentation
Flow Reqt Period (Optimization only)
In this text field, choose the period over which the Flow Requirement is to be
established - Day, Week, Month, Quarter, or Year. When left blank the horizon of the
optimization will be used as the Flow Reqt Period.
Note: When setting Flow Requirements for non-product specific transportation policies,
the requirement applies to each individual product. Aggregate flow requirements can be
specified on the Aggregate Flow Constraints data table.
Lane Name
In this text field, specify a name for this transportation lane that can be used in userdefined Mode Selection Rule scripts.

Name
In this text field, enter a unique name for each asset in your model.
Units
In this number field, enter the number of units of this asset that are available for use in
the network. Units must be a whole number (i.e., you cannot have half a truck). When
optimizing, the number of units entered in this field will act as a max number of asset
units. The software will automatically determine the optimal number of transportation
assets. The results will be in the Asset Summary Optimization Output table.
Note: Be sure to specify the Asset being used in the Asset field of the Transportation
Policies data table.
Type
In this drop down menu, select either Vehicle or Container. An asset is considered a
vehicle if it is able to move from one node to another, such as a Truck, Boat, Plane or
Train. An asset is a container if it can be loaded with product, but cannot move
between sites on its own, such as a pallet or railcar.
Expansion Only (Optimization Only)
If set to Yes, then the available number of assets cannot be less than any previous
period.
Unit Fixed Cost
In this number field, enter the total cost of owning or using each unit of this asset. This
is a fixed cost, not used to calculate profits or expenses in the network operation. It is
included on the summary report, and can be used to compare various scenarios.
Apply Fixed Cost to Horizon (Optimization Only)
During a multi-time period optimization, If set to yes, then the unit fixed cost will be used

In this number field, enter the weight at which your asset is considered full enough to be
dispatched. The Weight Fill Level acts as a trigger for certain Transportation policies.
Weight Capacity
In this number field, enter the maximum weight your asset is capable of holding.
Note: Weight Capacity must be greater than or equal to the Weight Fill Level. These
fields work hand-in-hand when you create your Transportation policies. If Weight
Capacity and Weight Fill Level are the same number, your asset will only be dispatched
when it is 100% full. On the other hand, if your Weight Fill Level is 100 pounds and
your Weight Capacity is 200 pounds, then your asset will be dispatched when it is 50%
full.

Review Period (Simulation only)
In this text field, enter how often inventory level is checked to see if a replenishment
order is necessary. Options for review period are Hourly, Daily, Weekly, Monthly, and
130
Data Tables
Continuous. Continuous means that every order that arrives will cause the inventory
level at that site to be checked to see if a replenishment order is necessary.
For many supply chains, automated inventory tracking means that they continuously
check the inventory level, replenishing almost the instant that the level falls below the
Reorder Point. However, there are also cases where the actual behavior of the system
is really better represented by a periodic review system.
Example: Your Lemonade Stand always knows how much inventory is on-hand, but
only wants to replenish once a day. In this case, a Review Period of Daily would result
in product being reordered once a day, but only if needed. How much is ordered
depends on the policy you have defined.
Initial Inventory
In this number field, enter how many units of this product is on-hand at this site when
the simulation begins running.
Note: If no data are entered, SC Guru assumes there are zero units on-hand when the
simulation begins.
In supply chain simulation, you are starting from scratch each time. Although your
model will quickly conform to a real world situation, at time zero, there will likely be
differences between the model and the real world. You can counteract some of these
differences by setting initial inventory levels in your model.
Inbound Cost
In this number field, enter the activity cost of handling and moving one unit of this
product from the receiving dock into inventory. This figure contributes to inbound
warehousing cost statistics in your simulation report. Inbound and outbound costs
include such costs as paper tracking procedures, handling equipment, and personnel.
Note: Inbound Cost does not include Transportation costs.
Outbound Cost
In this number field, enter the activity cost of removing one unit of this product from
inventory to the shipping dock. This figure contributes to outbound warehousing cost
statistics in your simulation report. Inbound and outbound costs include such costs as
paper tracking procedures, handling equipment, and personnel.

is less than the DOS Window, the window will be automatically adjusted to the number
of days passed during the simulation run. For DOS-Forecast based policies, if the
remaining time is less than the DOS Window, the new DOS window will be
automatically adjusted to the remaining days left in the simulation.
DOS Planning Lead Time
This number field is used for the DOS Demand-Based and DOS Forecast-Based
inventory policies. If allows the user to off set the DOS window by a number of days
either before the current day (DOS demand based) or ahead of the current day (DOS
Forecast based. Acceptable input in this field us any integer great than 0 and is
representative of the number of days offset.
Inventory Turns
This field allows you to specify a (piecewise) linear function from which the average
inventory can be calculated during optimization.
We define the following relationship between Average Inventory and Throughput:
Average Inventory = m times Throughput
Where m is the inverse of the inventory turns value.
We allow Average Inventory to be defined over multiple ranges of Throughput. The
format for the relationship is a series of pairs <lower range value, turns value>.
Consider the sample graph below. Up to 1000, the Average Inventory is (1/5) *
Throughput. Between 1000 and 3000, the Average Inventory is (1/8) * Throughput +
75. After 3000, the Average Inventory is (1/15) * Throughput + 250. This relationship is
to be entered as <0,5><1000,8><3000,15>. In the case the relationship between

Average Inventory and Throughput is simply linear, it is sufficient to input the turns value
(inverse slope) of this line; for example, 5.

Process Step
In this text field, enter a descriptive name for this particular step of the process that you

Work Center
In this text field, choose the work center used for this step in the process.
Routing Rule
In this text field specify if there is one possible route (Single Route option) for this
process or if there are more routes possible. Options for Multiple Routes are First
Available, Most Capacity and Probability.
Routing Rule Parameter
This is only applicable if the routing rule is set to Multiple Routes (Probability). Enter the
percentage of probability that this process will use the specified Next Process Step (can
also be None). If the chance is 25% that the specified Next Process Step will be used,
enter "25".
Next Process Step
In this text field, choose the next step of the process. When the process is complete,
choose None or leave the Next Process Step field blank.
Work Time per Unit
In this time field, enter the process time required for each unit. This time unit can
accept both probability distributions and straight time units (SEC, MIN or HR). If the
process specifies production for example, the Work Time Per Unit is multiplied by the
quantity of ordered product, to arrive at a total production time for this step.
Example: The Work Time Per Unit at the Lemonade Squeezing step is 6 SEC. The total
production time per unit for 1000 lemons is 6000 seconds or 100 minutes.
Work Time per Order
In this time field, enter the fixed amount of time required for each order that goes
through this step, regardless of the production quantity. The work time per order
139
Printed Documentation
includes time for such tasks as setup and changeover times. It is not exclusive of the
work time per unit; you can have both a fixed work time per order and a work time per
unit. This field accepts both straight time (SEC, MIN or HR) and probability
distributions.
Example: The Work Time Per Order at a work center is 1 HR. Work time per unit is 1
minute. If you have an order of 120 items, the total time of production at this step is 3
hours.
The Work Time Per Order field acts as an average setup time. How many setups are
required? Take the total flow divided by the "lot size", and that's how many setups (each
setup is the time per order field value) will be added on top of the processing time for
total capacity requirement.
For the example above, 500 units of P1 are required for production. If there is a "1 HR"
in the time per order field, and the lot size is "50", the total capacity requirement in hours
at the WC will be the production time (5*500/60) PLUS setup time (500 / 50 * 1).
Average Changeover Time Order (Optimization Only)
The time spent preparing the work center in between two orders.
Move Time
In this time field, enter the amount of time it takes to move the product from this process
step to the next in case a next process step is specified in the Next Process Step field.
Cost Per Unit
In this number field, enter the cost for each unit for this process step. Each step in a
process can have a different cost. For example, as an production order goes through
each routing step, costs accumulate until the order is complete. The total cost of the
order is then added to the site production cost statistics.
Setup Cost
In this number field, specify the initial costs for implementing the process step. Setup
Costs are applied for each batch, i.e. the setup costs are calculated based upon the lot
size and the number of units processed.
Resource
In this text field, choose the work resource that will be assigned to this process step.
Resource Usage Hours (Optimization Only)
140
Data Tables
In this number field, specify the number of hours the resource is used for this process
step.
Lot Size
In this number field, enter the lot size for this process step. The lot size is used to break
up a production quantity into smaller amounts. For example, if a production quantity of
1000 starts a process step with a lot size of 100, the production item will cause 10 items
of 100 each to be produced.
Yield
In this number field, enter the loss factor due to this process step. For example, if 10%
of the material that was input to a cutting production step (making skewed edges
straight) is lost due to the cutting, the yield factor is equal to 0.9: 90% of the material
that was inputted is outputted after this production step. Demand (from a
customer/facility or input of the next work center) determines the net production, that is
the amount that needs to be output of a certain work center. The input needed at a
work center (gross production) is calculated from the demand and the yield value.

Status
The status field defines whether this work center will be included, considered, or
excluded during optimization runs.
Type
This field enables you to specify whether this is an existing work center or a potential
work center. Along with the status, this field will determine which of the fixed startup
cost, fixed operating cost, and closing cost fields will be incurred during the network
optimization run.
Queue Capacity
In this number field, enter the maximum number of production orders allowable in the
queue leading up to the work center. If the value is set to INF, there are no limits on
how many production items could be queued up waiting for production. If the Queue
Capacity is reached, production items that are routed to this work center will be blocked,
and will not move until queue capacity is available.
Queue Selection Rule
Choose the way new orders will be lined up in the queue for this work center. For the
FIFO (first in first out) option, orders are queued in the order in which they arrive. In
case there are multiple routes specified for this work center in the processes table, the
First Available Resources rule checks which route will have the resources needed
available the soonest and queues the order accordingly (resources used by work
centers are specified on the Processes Table). The QueueOnly rule only puts the
orders into a queue, but does not trigger the production of any, it is assumed that this is
taken care of through a script (Scripts Table) when Queue Only is selected.
Capacity Period (Optimization Only)
In this text field, choose the period (Day, Week, Month, Quarter, or Year) over which the
cost numbers in the Fixed Startup <Cap/Cost> and Fixed Operating <Cap/Cost> fields
are applied.

Capacity Basis (Optimization Only)
In this text field, choose the unit measure you will use to determine the dimension of
shipment capacity in the Startup <Cap/Cost> and Operating <Cap/Cost> fields. Valid
Choices are
Quantity
Weight
Cubic
Time
Note: If the Capacity Basis is Time, the unit of measure in the Fixed Startup and Fixed
Operating graphs for capacity is hours. Be careful of the capacity basis that you set.
Typically, you'd use "Day" if you are using "Time" as the basis. Remember that the
basis is used to figure out the total aggregate capacity. If the start and end is set to be
1 year apart (in model options), you are running for 365 days. If you then set the basis
to "Time" and period to "Day", the cap/cost is in daily running hours for the work center.
In this case, if you set "8" as the capacity, the total hours available for the work center
for the year at that level is 365 * 8.
This capacity is consumed by work times specified in the processes table, enabling you
to model rough cut capacity.
The time per unit is multiplied by the total flow to get the total capacity required for flow
(for example, if the solution has 500 units of P1 getting produced on WC1, and the cycle
time is 5 minutes per unit, the total capacity required = 5 * 500 / 60 hours of capacity.)
Fixed Startup <Cap/Cost> (Optimization only)
In this field, enter a function that defines the relationship between startup capacities and
startup cost. The function is specified by a series of coordinates. The first number in
the coordinate indicates shipment capacity. The second number indicates the startup
cost.
For example, an entry of <0, 1000000> <500000, 2000000> <750000, 2500000>
indicates that before any products can be shipped, an initial expenditure of $1,000,000
must be invested. In order to get capacity to more than 500,000, an initial expenditure
of $2,000,000 is needed. For capacity to be greater than 750,000, an initial expenditure
of $2,500,000 is required.
Fixed Startup Costs are always applied to the optimization horizon.

Fixed Operating <Cap/Cost> (Optimization only)
In this field, enter a function that defines the relationship between operating capacity
and operating costs. The function is specified by a series of coordinates. The first
number in the coordinate indicates production capacity. The second number indicates
operating cost.
For example, an entry of <0,1000000><500000, 2000000> <15000000,INF> indicates
that there is an initial operation cost of $1,000,000 before any product is produced. In
order to get capacity to more than 500,000, the operating cost increases to $2,000,000.
The maximum capacity is 15,000,000 as indicated with a cost of infinite (INF). If the
cost is INF for a certain capacity level, that capacity is considered as a hard constraint.
Apply Fixed <Cap/Cost> To Horizon (Optimization Only)
In this field, select Yes or No from the drop down menu. When it is set to Yes, the
specified Cost and Capacity structure for the Fixed Operating Costs is applied over the
total length of the optimization. When periods are specified in the Multi-Time Periods

Pattern is directly related to Quantity. The pattern you select will take the total
aggregate quantity stated in the Quantity field and spread it out, as evenly as possible,
over the desired time frame. For example, If Quantity is less than the number of
occurrences in the Pattern, the software adds additional time between the recurring
production and the production. If Quantity is greater than the number of occurrences in
the Pattern, the software evenly distributes the quantity over the entire time amount.

A Row Col Table will look values up in a 2-dimensional table based on the row and
column headings.
Demand, Shipments, and Production Files will append the specified table(s) to the
Demand, Shipments, and Production input tables.
These files need to be organized in the same way as the Demand, Shipments and
Production tables are organized (number and order of columns need to equal for
example).
Connection String
In this text field, specify the name of the file that contains the data that will be used to
look values up (Row Col Table) or append data to the Demand, Shipments, and
Production tables (Demand, Shipment, and Production File options).
If this file is located in the same folder as the model (.sgm-file), then just listing the
name of the file is sufficient. In case the file resides in a different folder, the full path
needs to be entered here, e.g. C:\SCGmodels\DataForModel1.xls.
This field can be left blank in case the data is contained in an Access table within the
model (the .sgm-file) itself.
Record Source
In this text-field, specify the name of the Excel-sheet where the data is located or the
name of the Access-table within the model.
One can also specify a range where the data is located on an Excel-sheet, for example:
Sheet1$(B2:D10).
Dynamic Pipe (Simulation Only)
Dynamic input pipes allow the user to access rate tables as the simulation runs.
154
Data Tables
An example of how a dynamic input pipe can be used is when looking up transportation
rates based on shipment weight. Since the shipment weight is not determined until after
the model starts running, this rate must be accessed in real time.
In comparison, non-dynamic input pipes are used to calculate rates prior to the
simulation start and are useful for such rate calculations as distance based rates where
the distance within the lane is fixed throughout the model.
Field Map
In this text field, specify which variables in the model are mapped by the rows and
columns of the Record Source, if the Input Pipe Type is Row Col Table (leave blank
otherwise).
One needs to specify the names of the variables as they appear in the Access tables of
the model (the headings in the software tables are not necessarily identical to their
column headings in the underlying Access tables).
Also, attributes of a certain variable can be specified by using "Property.Attribute"
syntax.
If the rows in the record source for example refer to the State of the Source Site and the
columns refer to the State of the Destination Site, you will enter SourceSite.State;
DestinationSite.State in the Field Map field.
Following this example, the numbers in the specified Excel-sheet could be used to look
State-to-State transportation costs up for example. If the column-headings in Access
will contain the Destination Site State abbreviation, and the first column contains the
Source Site State abbreviation, these will be used to look the costs for shipping from a
certain source to a certain destination up.
Next, you can specify the name of this Input Pipe in the Cost or Avg Cost field (or both)
on the Transportation Policies table for one or multiple records.

Annual Schedules allows for us to change the operating schedule at a particular
site.
This should be used when the weekly operating schedules at a site varies through the
simulation horizon. The annual schedule allows for UP and DOWN state changes to be
specified at that particular calendar date, where UP signifies if the site is operational
and DOWN signifies the site being not operational.
This allows specific days such as holidays to be programmed. The annual schedule can
also be used to activate a new weekly schedule to allow for seasonal variation.

Data Tables
Aggregate Site Constraints
Aggregate constraint tables allow the specification of additional rules to the
supply chain network defined by other tables. All tables define aggregated
quantities over sites, products, and time periods.
Aggregate site constraints define minimum and maximum number of open sites allowed
in a set of periods.
Period Name
This field is not required, however if you are running a multi-period model, it will
consider the entire model horizon if left blank. This field allows the user to enter a
specific period for the site requirement. In multi-period models, once a potential site has
been opened, it cannot be closed.
Site Name
This field is required and allows the user to choose from a set of available sites or site
sets, however for the model to be feasible included sites must be set to
potential/consider. If a single site is placed here it can only be opened or not opened
and the relative max and min open sites must be either 1 or 0 or force open/force not
open.
Min Open Sites
Given a set of sites this allows the user to place a constraint that at least a certain
amount of sites need to be open in the specified time period. If time period is left blank
it will apply to the entire model horizon. If the user has only a single site in the site
name, this field can only be 0 or 1 or the model will be infeasible. Only integers can be
entered in this field. This number must be either less than or equal to the number
entered into the max open sites field or left blank.
Max Open Sites
Given a set of sites this allows the user to place a constraint that at most a certain
amount of sites need to be open in the specified time period. If time period is left blank
it will apply to the entire model horizon. If the user has only a single site in the site
name, this field can only be 0 or 1 or the model will be infeasible. Only integers can be
entered in this field. This number must be either greater than or equal to the number
entered into the min open sites field or left blank.

Overview
Similar to Aggregate Flow Count Constraints, we can set up Production based
constraints in SCG, pertaining to Sites, Products and Periods. Consider the structure
below, where there are 2 sites that can hold 2 products in 2 periods.
In the absence of any constraints, the structure would allow for 8 (23) different
scenarios. For example, we may only want one product produced at any one period.
This is how we would set it up.
Steps
1. Grouping SITE 1 and SITE 2 as a ’Set’ (group function)
2. Grouping PROD 1 and PROD 2 as a ’Set’ (group function)
3. Inputting these Set groups as the Site Name and Product Name in the Production
Flow Count Constraints table
4. Accessing the Aggregate Flow Count Constraints table and subsequently setting Site
Aggregated to ’Yes’ while setting Product Aggregated and Period Aggregated to ’No’.
5. Setting Count Value to ’2’ and Count Type to ’Fixed’
Explanation
By aggregating the Destination Sites, Products and Modes we are essentially
disregarding the various possible flows that are due to these variables.
163
Printed Documentation
This results in the optimizer having to choose 2 out of 4 options.
• Prod 1 in Period 1
• Prod 2 in Period 1
• Prod 1 in Period 2
• Prod 2 in Period 2
thus achieving our goal.
Summary
An interesting point to note (and subsequently test our understanding) would be that if
all the Aggregate fields (Site, Product, Period) are set to ’Yes’, we are in essence not
setting any constraints. This is because when all the fields are aggregated, there would
be only ’one’ possible flow. It should also be noted that like ’Fixed’ Count Type, there is
also a ’Min’ and ’Max’ function.

Aggregate Flow Count Constraint Notes

Overview
In Supply Chain Guru, it is possible to set up intricate constraints in the model linking
the following 5 variables; Source, Destination, Product, Mode and Period.
Consider the simple network structure below.
In the absence of any constraints, the structure would allow for 32 (25) different flows.
An example would flow of PROD 1 from MFG 1 to CZ 2 in PERIOD 1 by MODE 2.
However, we may want to model all the flow to happen in only one period, and originate
from only one MFG site. We would then set up this situation in SCG through the
following steps.
Steps
1. Grouping MFG 1 and MFG 2 as a ’Set’ (group function)
2. Grouping CZ 1 and CZ 2 as a ’Set’ (group function)
3. Inputting these Set groups as the Source Site and Destination Site
173
Printed Documentation
4. Accessing the Aggregate Flow Count Constraints table and subsequently setting
Source Site Aggregated and Period Aggregated to ’No’ while setting Destination Site
Aggregated, Product Aggregated and Mode Aggregated to ’Yes’.
5. Setting Count Value to ’1’ and Count Type to ’Fixed’
Explanation
By aggregating the Destination Sites, Products and Modes we are essentially
disregarding the various possible flows that are due to these variables.
This results in the optimizer having to choose between 4 flows. The end result will look
as show above, where MFG and PERIOD are the optimal MFG to source from and
PERIOD to perform the events.
Summary
An interesting point to note (and subsequently test our understanding) would be that if
all the Aggregate fields (Source, Destination, Product, Mode, Period) are set to ’Yes’,
we are in essence not setting any constraints. This is because when all the fields are
174

aggregated, there would be only ’one’ possible flow. It should also be noted that like
’Fixed’ Count Type, there is also a ’Min’ and ’Max’ function.

Global Variables
Name
In this text field, enter a unique name for this global variable.
Type
In this field, you can select whether the variable will be an integer variable or a real
variable.
Value
In this field, you can enter the initial value for the variable.
For variables that have dimensions specified (arrays), you can initialize individual
elements in the array by making the value field a comma separated list of values, such
as: 1,5,6,1,4,1,3,5,6,7,2. For two-dimensional arrays, each row is completely initialized
before moving to the next. Higher dimensional arrays cannot be initialized through the
values field.
For arrays, you can also load data directly into the array from an external MS Excel
spreadsheet, by simply listing a valid path as the value.
Note: The external spreadsheet initialization requires that MS Excel is installed on the
PC where the software is being run. The spreadsheet should only have 1 single
worksheet, and should only consist of numeric values that will be loaded into the array.
Dimensions
In this field, enter the dimensions of the global variable if you wish to create an indexed
variable (array). Leaving this field blank will make this variable a single value variable.

Optimization
Supply Chain Optimization
Optimization differs from simulation in that it looks for the optimal design parameters for
your supply chain model, rather than describing its behavior as in a simulation. An
optimization searches a large number of possible solutions to your supply chain model,
selecting the best one involved in site selection, product flow requirements, and
capacity with the objective of either minimizing cost or maximizing profit.

Greenfield Algorithm
Greenfield Analysis allows us to determine the optimum site of a Distribution Center (s),
based on customer demand and location.
One thing to note is that the Greenfield Analysis finds the optimum DC based only on
the customer locations and their demand; it does not look at the manufacturing site(s) in
the analysis. If we want to find an optimum Distribution Center that takes into account
the manufacturing sites, we would then include a few potential distribution centers in the
model and solve optimally using Guru.

How to perform a Greenfield analysis?
1. Select the number of planar DC’s that you would like to find in your model in the
’Scenarios’ tab of the Optimization Control Panel.
2. In the same tab, select ’Planar Location Method For Greenfield Analysis’ under
the ’Algorithm Options’.
Hit the ’Go’ button and the location of the optimum DC(s) will be populated in the
’Sites’ table of your current model.

Optimization
Optimization Control Panel
The Guru Network Optimization Control Panel contains 5 tabs: Control Panel, Options,
Scenarios, Infeasibility Tools, and Solver Stats. The Guru Network Optimization control
panel appears after clicking the Run Network Optimization button.
Optimization Objective
There are two possible optimization objectives. You can choose to:
Minimize Costs: When you minimize cost, SC Guru finds an optimal solution
that minimizes the cost function.
Cost = Total fixed operating and startup costs + total closing costs + total production
costs + total sourcing costs + total transportation costs + total duty costs + total
warehousing costs + total inventory holding costs + total in-transit inventory costs + total
transportation asset costs + total work resource costs
Maximize Profit: When you maximize profit, SC Guru finds a solution to
maximize the profit function.
Profit = Revenue minus Cost
These are mutually exclusive objectives. Selecting one will cause an optimization to
ignore the other.
Verify Network Before Optimizing
Just as in a simulation, you should verify your optimization data before making an
optimization run. To do this, check the Verify Network Before Optimizing option on the
Optimization Control Panel.
Batch Run All Models
Check this box if you want to optimize all models in the current project in one batch run.
Generate Optimization Input Files
If you rerun an optimization after you have changed only settings on the four input tabs
of the Guru Network Optimization Form (Control Panel, Options, Scenarios and
Infeasibility Tools), you can un-check this box and then no new Optimization Input Files
will be generated, but the already generated Optimization Input Files from the previous
run will be used. Only when changing data in the model data tables themselves it is
181
Printed Documentation
necessary to check this box and generate the optimization input files before an
optimization is run.
Optimization Progress
In this window the progress of the optimization run is updated real-time.
Algorithm
Solve Optimally – Solve as a mixed integer problem
Solve as a Linear Program – Solve linearly ignoring integrality constraints. If the
problem requires the use of integer variables, the solution is likely to be invalid.
This option is included to obtain approximate solutions for large-scale integer
programs as well as a first-cut data verification tool in the early stages of a
modeling project.
Infeasibility Analysis – In the event where the optimization run returned as
infeasible, we can ask Supply Chain Guru to perform one of the several
Infeasibility Analysis tools that are available. See also the Infeasibility Tools tab.
Planar Location Method for Greenfield Analysis – This is a heuristic used to
determine the ideal location for a single (or more) DC based upon the location of
the customers and their respective demand quantities.
182
Optimization
Optimization Control Panel - Infeasibility Tools
If the Solve Optimally algorithm returns a Problem Infeasible message, the user has
several tools available to analyze the cause of infeasibility:
Check Network Structure Logic
Choosing this method of analyzing an infeasible model will identify if there are any
logical problems with the structure of the network itself.
Determine Supply-Demand Imbalances
This algorithm will check for any imbalances between supply and demand. For
example, if a site has a maximum capacity to deliver 100 units a year and it is the only
source of a certain customer that demands 200 units a year. This supply-demand
imbalance will be found and displayed.
Solve with the following hard constraints only
To narrow down and identify the possible causes of infeasibility, one can solve with
selected hard constraints only. The other hard constraints will not be imposed in this
case.
Note: No new Optimization Input files are generated when the algorithm is "Infeasibility
Analysis". Therefore, when changing a model's input tables to solve the infeasibility,
first the Solve Optimally algorithm needs to be run to generate new input files before the
Infeasibility Analysis can be run again (otherwise it will be run on the older model data
that doesn't contain the most recent changes).
Algorithm

Maximum Product Flow Value
Network optimization calculations require an estimate of a maximum flow amount that
can come out of each site. This option allows advanced users to override the values
that are automatically calculated by SC Guru by setting the value in the User-Defined
box. Automatic calculation of maximum throughput values, which is the default, is
recommended for most users.
Additional Settings
Produce LP File – When checking the ’Produce LP File box’, a complete linear
program formulation of the model will be generated. This is the .LP file in the
NetOptimData subfolder of the directory where the model is saved.
Include Customization in – A user can define custom constraints by writing
them in the Mosel language in a .mos file that needs to be placed in the folder
where the SCG model is saved. An accompanying .dat file of the same name as
the .mos file should be placed in the same folder.
Note that only licensed users have access to this source file, in the evaluation version of
SC Guru it is not possible to include any custom constraints in the optimization.
Omit Objective Function – This setting sets the Optimizer to ignore the
Objective functions such as profit or cost for example, resulting in the returned
solution not being ’optimized’ towards a certain goal
Performance Settings
Presolve
’Use All’ enables a complete set of algorithms to be applied to the problem in an
effort to reduce its size and eliminate redundant variables and constraints, so that
the problem can be solved relatively easily by the optimization algorithm.
’Do Not Use Any’ causes no algorithms to be applied to pre-solve the problem.
’Use All Except Integer Reductions’ option causes only a subset of all the
possible pre-solve algorithms to be applied to reduce the size of the problem and
eliminate redundant variables and constraints.
Solution Strategy
184
Optimization
The Aggressive Root Cuts strategy increases the time to solve the problem at the root
by applying more heuristics and tries to reduce the solution space for the subsequent
enumeration. For some bigger problems this can be worthwhile, but in general
choosing the Automatic strategy is recommended.
Termination Settings
Relative Gap (%)
Relative difference between a feasible solution and a bound calculated by the
optimization solver. The greater the gap value defined by the user, the quicker the
solution will be found. This field accepts values between 0 and 100. The default directs
the solver to find an optimal solution.
The Relative Gap is defined as: abs (BestBound - objective Value) / abs (BestBound)
Absolute Gap
The Absolute Gap is the absolute difference between a feasible solution and a bound
calculated by the optimization solver. The greater the gap value defined by the user,
the quicker the solution will be found. The default directs the solver to find an optimal
solution.
The Absolute Gap is defined as: abs (BestBound - objective Value)
Cutoff Value
Enter the objective function value of a known, or estimated feasible solution. If your
objective is to minimize cost, for example, a value of 25 million will eliminate any
solution that costs more than 25 million. The closer this figure comes to the true optimal
objective function value, the quicker the solver will find an optimal solution.
Note: The danger here is in making this figure too high when maximizing profit, or too
low when minimizing cost. In this case, the optimization process may run for a long
time attempting to find a solution that simply is not attainable. You will then be
prompted "Problem Infeasible”. The default for this field is "None.”
Time Limit (seconds)
If after this amount of time the optimal solution hasn't been found yet, the optimization
will terminate. If a solution has been found within this period, it will be accepted as the
optimal solution. One can also choose to let the optimization run until at least one
solution has been found by checking the "Continue until at least one solution is found"
box.
Feasibility Tolerance
185
Printed Documentation
The Optimizer works with tolerance values for integer feasibility and solution feasibility
that are typically of the order of 10-6 by default. When evaluating a solution, for instance
by performing comparisons, it is important to take into account these tolerances.
After retrieving the feasibility tolerance of the Optimizer we set the comparison tolerance
of Mosel (ZEROTOL) to this value. This means, for example, the test x = 0 evaluates to
true if x lies between -ZEROTOL and ZEROTOL, x 0 is true if the value of x is at most
ZEROTOL, and x > 0 is fulfilled if x is greater than ZEROTOL.
Comparisons in Mosel always use a tolerance, with a very small default value. By
resetting this parameter to the Optimizer feasibility tolerance Mosel evaluates solution
values just like the Optimizer.
MIP Tolerance
Similar to Feasibility Tolerance, this sets the tolerance for what is considered to be an
integer by the Optimizer. By default this is set to 5×10-6 which means that any range of
values between 2.999995 and 3.000005 for example would be considered as an integer
value of 3. Larger tolerances can help in speeding up the solution deriving process.

Optimization Control Panel - Scenarios
Quick Site Scenarios
The Quick Site Scenarios dialog allows you to establish how the sites should be treated
during optimization. In the Sites data table, the site type is defined: customer, existing
facility, or potential facility. Also, site status: consider, include, or exclude. With this
dialog, you can quickly change the site status for all sites of a certain type or choose to
use the status defined in the Sites data table. To use the Quick Site Scenarios dialog,
simply select the status you want to give to all sites of a particular type:
As in Sites Table - Use the site status defined in the Sites data table.
Consider All - Change all sites of this type to the consider status. In an optimization,
SC Guru can recommend that sites with the Consider status be opened or closed if its
profitability does not meet expectations or needs.
Include All - Change all sites of this type to the include status. These sites will be
included in the solution.
Note: The Quick Site Options do not change the site Status fields in the Sites data
table.
Alternative Facility Limits
Min Consider Sites: network optimization can consider alternate sites and open an
optimal number of sites. This option allows users to force SC Guru to open (or leave
open) a minimum number of alternate sites.
Max Consider Sites: network optimization can consider alternate sites and open an
optimal number of sites. This option allows users to force SC Guru to open (or leave
open) a maximum number of alternate sites.
Scenario Options
Bundle All Customer Demand: Check this box if you want to aggregated all the demand
by customers such that when a customer demands multiple products, these are sourced
in equal ratios from one or multiple sites (proportional to the demand quantities for these
products).
Classify Demand By Due Date: Check this box if you want to aggregate (and
subsequently prioritize) all the demand by the date it is due to the customer such that
the transportation time of the last mode to deliver an order to a customer is constrained
by the value set in the Due Date field on the Demand table. If this box is unchecked,
the Due Date field doesn't influence the outcome of an optimization.

Carbon Footprinting Analysis
A Carbon Footprinting analysis essentially means calculating and reporting the GHG
emissions of a modeled supply chain. In a carbon footprinting analysis, a supply chain
model is built and carbon emissions data is included as part of the modeling effort.
When the model is simulated or optimized, the GHG emissions are reported in the
output.
Carbon footprinting is usually, but not necessarily, performed as part of a broader
supply chain analysis project. The objective of this kind of analysis is to understand the
current carbon footprint, and the carbon footprint of any alternatives being considered.
The GHG emissions are reported (sim and opt), but do not otherwise affect the model
algorithms or modeling functions.
192
Optimization
Carbon Offset Optimization
Carbon Offset Optimization: although it is certainly possible to redesign supply chain
networks to reduce their GHG emissions, it is not possible to entirely eliminate them.
However, there are activities around the world which are known to relatively reduce
GHG emissions (such as planting trees, or reducing emissions more than are required
by global reduction standards). Organizations that have carried out such GHG
reduction efforts essentially have ”credits” which have been commoditized and are now
sold on open markets.
In order to further reduce or possibly even completely offset a network’s Carbon
Footprint, it is possible to purchase ”Carbon Offset Credits.” A Carbon Offset Credit has
a price set by the world markets, but has historically fluctuated between $2 to $25 per
ton of CO2, depending on timing in the specific market.
Thus, a company that has a carbon footprint of 1 Million tons of CO2 in a year, but
cannot reduce change its network to reduce its own emissions could still affect an
equivalent 10% reduction in its Carbon Footprint by purchasing 100,000 Carbon Credits
from the marketplace.
Supply Chain Guru’s GHG Modeling functionality incorporates this by manually setting
the Carbon Offset Credits as an input (for sim and opt) in the Greenhouse Gas Options
Panel. However, in optimization, you can also specify the Carbon Offset Credit
purchase to be a decision variable, with the cost of the credits incorporated into the total
cost calculation of the objective function.
To perform a Carbon Offset Optimization, simply set the Optimize Offsets option to true,
and the Carbon Offsets will be chosen by the optimizer as part of the decision to
maximize profit or minimize cost subject to all constraints. Note that this optimization
option can be used in concert with the GHG reduction constraints, letting the user
choose to model the option of buying Carbon Offsets to achieve GHG reduction goals or
not.
193
Printed Documentation
Data Units and Terminology
In popular literature and the common vernacular, Greenhouse Gas (GHG) emissions
are often used interchangeably with Carbon Dioxide (CO2) emissions. In fact, there are
numerous gases that are associated with greenhouse gas effects, including CO2,
methane, and water vapor. For modeling purposes, and keeping with current common
convention, all GHG emissions will be input and output in terms of CO2 equivalent units.
Typically this is kilograms (kg) but could also be input and output in terms of CO2
metric tons (1,000kg). Units will not be set explicitly in Guru in the initial
implementation; the modeler will decide whether they are using kg or tons, and will need
to convert input values into the same unit. Output values will be reported in the same
unit.
A Carbon Footprint is the net sum of all the GHG emissions produced by a supply chain
during the period of interest minus any carbon offsets.

Optimization
GHG Reduction Efforts
In a GHG reduction effort, GHG emissions throughout the supply chain are modeled,
but additionally, the total carbon emissions of the supply chain are incorporated into the
optimization formulation as a constraint. Typically, the modeler will start with a baseline
(current carbon footprint with no reduction constraint), and run several iterations of an
optimization. In each iteration, the total Carbon Footprint is constrained to be equal or
less than a specified total, usually as a percentage of the baseline or as-is footprint.
For example, if a baseline simulation (or As-Is optimization flow model) has a Carbon
Footprint of 1 million tons CO2 each year, a Carbon Footprint constraint of 900,000 tons
could be set, equivalent to a 10% reduction in GHG emissions, and the model reoptimized; set to 20% reduction, and re-run, etc. This will provide the modeler with a
series of alternative network designs, each of which demonstrates the cost or profit
optimized design which still meets the GHG reduction goal.

Green House Gas Emissions Testing
SimServer within Supply Chain Guru has implemented preliminary support for tracking
and reporting GHG emissions. SimServer now provides several new properties to
specify GHG emission levels as follows:
Sites.FixedCO2
Sites.CO2Basis
Sites.Products.Sources.SourcingUnitCO2
Lanes.Modes.TransportationCO2
-The user sets the Sites.FixedCO2 property to cause a fixed GHG cost to be recorded
periodically.
-The reporting period is set by the Cost Capacity property, which also specifies the
reporting period for monetary fixed cost reporting.
-The FixedCO2 property can be optionally set to a throughput-driven stepped list with
an optional throughput cap. The format for this is the same as for fixed capacity costs.
The user will set the CO2Basis property to the basis for throughput relating to the
reporting of GHG emissions. The default value is Weight-Distance.
-The SourcingUnitCO2 property is set to incur a GHG emissions cost for production
(Make) related sourcing policies. The property is ignored in all other cases.
-The TransportationCO2 property is set to incur a GHG emissions cost during
transportation. The basis is assumed to be Qty.
Several new properties have been added to report GHG emissions as follows:
Sites.TotalFixedCO2.Statistics
Sites.FixedCO2.Statistics
Sites.TotalSourcingCO2.Statistics
Sites.TotalTransportationCO2.Statistics
200
Optimization
Typically, the aggregate totals would be directed to the main report pipe and the
FixedCO2 statistic would be set to a Time Series Observation pipe to report periodic
fixed costs.
In addition to the above, the shipment transaction log has changed to incorporate a new

follows:

Simulation
Simulation Engine
SC Guru uses an external application program, called SimServer, to simulate your
supply chain. When SC Guru builds and runs a model, the animated display of your
supply chain is SimServer running your data. SC Guru then imports the statistics
SimServer generates for its reports.
The SimServer window displays a map of your supply chain model, graphically
representing your sites and your transportation lanes. As shipments are dispatched,
icons representing your shipments travel between sites, moving at the designated
transportation speed. If your simulation includes work centers, work resources, and
processes, your submodel will be graphically displayed below the animation map.
SimServer has its own menus and commands, giving you a certain amount of control
over the display features of your animation. The following discussion will explain some
of the features needed to use SimServer in conjunction with SC Guru.
SimServer Features
There are three features on the SimServer window when your simulation is run: the
menu bar, the animation speed bar, and the display. You can use the menu bar
commands to pause or end the simulation and control the size of the display. You can
use the progress bar to control simulation speed. The simulation clock tracks the
simulation run time. The display gives you a powerful "bird’s-eye-view" to observe the
dynamics and progress of your supply chain.

Running a Simulation
After setting your simulation options, you can run your simulation. SC Guru provides
you with options on how your simulation is run.
Simulate Supply Chain - This is the default setting for simulation. Your model is
tested for errors and animated in the SimServer window. This option is also available
by clicking
on the Analysis toolbar or pressing F7.
Simulate Supply Chain Scenarios - This option runs your simulation for all models
contained in the project without animation and without conducting model tests.
Build Model Only- This option runs your simulation without building the graphic
animation. As a result, your simulation will run significantly faster.
Run Model Without Build- Select this option to run your simulation without verifying
syntax or logic errors. For large models, this can significantly decrease the length of
time required to build the simulation model. However, if there are any modeling or data
errors in your supply chain, the resulting simulation model may not run correctly. This
option should only be used if you are sure that the model data are in the correct format.
Import Simulation Output- This option runs your simulation without animation and
without conducting a model test.
When you run a simulation, the SC Guru Error Log will be displayed if you have chosen
to verify your model. The SimServer window will be displayed for every simulation run;
however, if you have elected to run your simulation without animation, you will not see
animated shipments. Assuming there are no errors that prevent your model from
running, all the simulated menu options output the same statistical results.

Transaction Reports
SC Guru automatically creates Transaction reports after a simulation has been run.
These provide more detail than a simulation or optimization summary report. SC Guru
outputs these reports as comma-separated value (.CSV) files that you can open in MS
Excel. They are located in the directory in which you saved your model. There are
three types of transaction reports:
Demand Report - Lists the time each order arrives, the site involved, the
product ordered, the quantity of product ordered, and the price.
Shipment Report - Lists the time each order was shipped, the source
site, the destination site, the product ordered, the quantity of product
ordered, the total weight/cubic, the cost of shipment, the mode
(transportation policy), and the shipment number.
Production Report - Lists the time production begins, the production site
involved, the product made, the quantity of product made, and, in case a
work center is used to produce the product, the name of the work center.
This report is used for sites with a Make sourcing policy only.

Four Step Methodology
The Four Step Methodology
Supply chain strategic planning problems involve decisions about how a company’s
internal supply chain and external linkages (both with suppliers and customers) are
organized.
The elements, or objects, that make up the system, can be considered a supply chain’s
structure. Some examples of structural elements include: products, sites, shipments,
transportation assets, machines, and workers. These objects all interact with each
other, and how they do so is governed by the rules, or policies, that the objects follow.
Policies can be rules that govern how much inventory is stocked at a given site, or how
a site reacts when an order is received, or how that site deals with product shipments
when they arrive. By combining a supply chain structure with a set of supply chain
policies, one can arrive at a very precise description of a corporate supply chain. Most
strategic decisions and planning activities involve either proposed changes to the supply
chain’s structure, or modifications to the supply chain’s policies (behavior).
LLamasoft, Inc has developed a four-step methodology that is intended to ensure that
the proper simulation and optimization techniques are employed and used appropriately
in support of both decisions that change structure and decisions that change policies.
The four-step methodology starts by assuming that the strategic supply chain design
process is being drawn on a ”r;clean sheet of paper.” In other words, it begins with little
more than a list of customer demand points, from which the methodology moves
through the entire strategic design with no presupposed objects.

Step 1: Network Optimization
The objective of Step One is to arrive at an overall network structure that is
efficient, meets all current demands, minimizes structurally based cost issues,
and supports any other management constraints.
To do this, a linear- mixed integer (LP-MIP) programming model is formulated, then
solved.
The power of network optimization modeling lies in two main strengths:
1. It can be proven to provide the mathematically global optimal solution to the problem.
The solver will, with near certainty (depending on the specific algorithm), locate the least
cost feasible network structure.
2. Network optimization models can handle millions and millions of possible alternative
designs in a very short time. Large, global, multimodal distribution networks can be
optimized effectively.
Data requirements for Step One include:
List of candidate sites, candidate site locations
List of demand sites, demand locations
Total demand quantities per location
Cost per unit of flow and out of each site
Cost of transporting units in and out
Constraints, such as requiring that every demand point is within 500 miles of a
warehouse
270
Supply Chain Knowledge Center
The output results of Step One include:
Number of summary statistics, such as total cost, total flow in and out of each
node
The breakdown of transportation mode usage by lane
The manufacturing capacity utilized by the design
Which nodes supply which other nodes.
The technology for network optimization has been successfully deployed and used by
thousands of practitioners. Some of the more advanced tools for performing network
optimization also have some capabilities to do multi-time period optimizations,
incorporate production and throughput constraints, and handle complicated tax and tariff
calculations.
Go to Step 2: Policy Optimization
271
Printed Documentation
Step 2: Policy Optimization
Network optimization provided a powerful means of selecting an optimal supply
chain structure. However, the design can still be improved through attempting to
optimize the policy choices used to govern the network’s behavior.
Step Two involves the running of multiple simulations in order to observe the effects of
different policies and select the best set. This step can be performed by the analyst in a
manual approach, but this is a tedious and difficult method. Instead, a better method is to
use simulation-optimization as a modeling and problem solving approach which will
result in an ”optimized” simulation model that prescribes the inventory, sourcing, and
transportation policies which should be adopted from a strategic level in the network
design.
Simulation-optimization applies is a direct optimization method which applies an
intelligent algorithm to a discrete event simulation model. Only in the last few years has
this technique been commercialized and studied enough to render it a feasible method for
practitioners.
Policy Optimization is a cutting edge technology that can produce extremely valuable
recommendations for policy improvement and better supply chain designs.

272
Supply Chain Knowledge Center
Step 3: Network Simulation
While Steps One and Two will produce an ”optimal” supply chain structure, it
really ignores the issues of how the network will actually behave over time. As a
result, it tells you what supply chain network design to select, but it cannot tell
you exactly what will happen when that design is actually implemented.
In this Network Simulation step, a discrete event simulation model is built to replicate
the design that was produced in Step One. However, this design is simply a structure,
or ”shell,” of a proposed network design.
Most notably, in Step One and Two, demand data was aggregated and process logic
was not needed. In Step Three, the user must define the rules, or policies, which govern
how inventory is managed and when it is replaced. Sourcing and transportation policies
must also be defined.
To perform Network Simulation, time related demand data must be incorporated into the
model. While aggregate quantities were sufficient for flow optimization, in order to
simulate the demand properly, the model must know how the demand arrives over time.
Some of the data requirements for Step Three include:
List of demand sites, demand locations
Total demand quantities per location
Cost per unit of flow and out of each site
Cost of transporting units in and out
Constraints, such as requiring that every demand point is within 500 miles of a
warehouse
273
Printed Documentation
Network Simulation’s strengths include the ability to predict very accurately how well a
design will perform, in a variety of metric categories, such as inventory level, cycle time
measurement, warehouse fill rate, and detailed costing.

274
Supply Chain Knowledge Center
Step 4: Design for Robustness
The final step in the Four Step Methodology is Design for Robustness. The
objective of this step is to ensure that the final selection of the supply chain’s
network structure and policies will operate well under a wide variety of situations.
During the first three steps of the Methodology, the user assumes that the design is
being improved to operate as efficiently and effectively as possible Perhaps more
importantly, performed properly, Step Four will ensure that the selected supply chain
design will, under less than expected or unusual circumstances will not perform
unacceptably poor. This should not be confused with simple variance.
In Steps Two and Three, random variance may have been introduced to produce more
realistic approaches. So, Step Four is not centered around randomness and its effects;
rather, it is the evaluation of the results of changing some of the external ”given” data
assumptions.
There are no guidelines that would predict which technique to use for which answer.
Instead, Step Four relies heavily on the knowledge and expertise of its users.

Planning a Model
A good amount of planning is necessary to make your model resemble your real
operations. Prepare to spend some time outlining the various components of your
network. You might find that some old-fashioned paper and pencil work now saves a lot
of rework later. The following list of preliminary steps is a good guide for planning your
model.
Step 1: Decide on a simulation, optimization, or both
SC Guru functionality allows you to simulate and/or optimize your supply chain. A
simulation mimics the behavior of your supply chain in the past, present, or future. By
simulating your supply chain, you can observe real world behaviors and create alternate
scenarios. An optimization finds the optimal design parameters for your supply chain.
Using a combination of simulation and optimization allows you to develop baseline
comparisons, analyze alternative scenarios, and make an informed decision as to the
best possible supply chain. Since simulation and optimization, in many cases, require
different data, determine early whether you will use one or both functions as you plan
your model.
Step 2: List Sites
List all the sites in your supply chain where products can be demanded, manufactured,
shipped from, or stored.
Step 3: List Products
List all the products that you make or sell at all your various sites. If a product is made,
also list the component products that make up each product.
Step 4: Decide if Products are in-sourced or outsourced
Decide if a product is manufactured at any of your sites or if it enters your supply chain
as a complete, ready-to-sell product. If a product is made at any sites you have three
choices:
Approximate production by determining how long it will take to make the product (the
time delay) and the cost of making it.
Combine cost and time delay approximation with a Bill of Materials, a list of all
components used to make an end product.
Or
Create Guru submodels. Submodels detail the steps in the production process. You
determine the steps in the process, the resources needed, and how the steps and
resources fit together.
278
Supply Chain Knowledge Center
Step 5: Decide how Products are stocked
Decide how much product quantity is maintained at each stocking point and how each
product is replenished.
Step 6: List Transportation Assets (optional)
Is your product carried to and from sites by airplane, boat, or train? List all the means
available to each site.
Step 7: List Work Centers and Work Resources (optional)
If you are manufacturing a product at any site and choose to define submodels, you will
need to list all the equipment and personnel resources needed to make your product.
Modeling Over Time
Keep in mind as you design and build your simulation model that you are creating a
dynamic facsimile of your supply chain, not simply a spreadsheet of products and
prices. Your simulation will result in vastly different output based on your recreating, as
closely as possible, dynamic considerations of inventory and transportation
management, as well as production time and use of resources.
Modeling For Variability
No supply chain behaves the same way every day. Variability is constantly at work.
For example, transportation assets breakdown, work resources suddenly become
unavailable, or demand increases dramatically. Familiarity with SC Guru’s features
provides you with a means to create alternative and complex simulation scenarios that
take variability into account.
Simulation vs. Optimization
A unique feature of SC Guru is that it allows you to perform simulation and optimization
runs on the same model. You can choose simply to simulate your supply chain over a
specified time period and evaluate your business scenario; or you can allow SC Guru to
consider alternatives, and list recommendations based on your desired objectives to
minimize cost or maximize profit.
279
Printed Documentation
Push Vs. Pull
The relationship between a the movement of products between manufacturer and
customer customers is commonly depicted by the terms "push" and "pull".
PUSH System
This system is characterized by a production driven product movement.
The manufacturer initiates orders through the supply chain system based
upon past orders or long term forecast.
In Supply Chain GuruTM, the PUSH system is modeled using the Shipments
table.
PULL System
In this system, the customer places an order for a product and receives the
product through the supply chain. It is often called a "demand driven"
system.
In Supply Chain GuruTM, the PUSH system is modeled using the Demand
table.
A supply chain is almost always a combination of both push and pull, where the
interface between the push and pull stages is considered the push-pull boundary.
