QUESTION EIGHT
a) You are managing a group of 10 technicians. These individuals undertake in-home servicing
of electrical systems and are called by telephone for either emergency or pre arranged visits.
They charge a minimum call out fee that covers the first 15 minutes of their visit plus
travelling time. Beyond the first fifteen minutes they charge in minimum blocks of 15
minutes plus any materials that might be necessary to carry out the job. The average call out
takes 1 hour. The workers usually are available for eight hours a day but with 2 coffee
breaks of 15 minutes each and a half hour lunch break, they actually work a 7 hour day.
Taking time off and illness into account reduces the electricians’ available time by 20%. This
means the 7 hours per day is reduced to a 5 hour and 36 minute day (5.6 hours)
If actual
work is only 200 hours billed in the week then (a) What is the capacity utilisation of the
team? (b) What is their efficiency? [15marks]
a) To calculate the capacity utilization of the team, we first need to calculate their maximum
capacity. Since they work for 5.6 hours per day, the maximum capacity for a week is:
Maximum capacity = 5.6 hours/day x 5 days/week
= 28 hours/week
To calculate the capacity utilization, we divide the actual work done by the maximum capacity:
Capacity utilization = Actual work done / Maximum capacity
Capacity utilization = 200 hours / 28 hours/week
= 7.14
Therefore, the capacity utilization of the team is 7.14.
b) To calculate the efficiency of the team, we need to compare the actual work done to the time
available for work. The time available for work is:
Time available for work = 5.6 hours/day x 5 days/week = 28 hours/week
Taking into account the 20% reduction in available time due to time off and illness, the time
available for work is:
Time available for work = 28 hours/week x (1 - 0.2) = 22.4 hours/week
The efficiency of the team is then calculated as:
Efficiency = Actual work done / Time available for work
Efficiency = 200 hours / 22.4 hours/week = 8.93
Therefore, the efficiency of the team is 8.93.

b) Discuss the “opportunity costs in inventory management highlighting its importance
production. Use diagrammatic illustration where necessary.
In inventory management, opportunity cost refers to the cost of forgoing the next best
alternative use of the resources tied up in inventory. It represents the potential benefit or
profit that could have been gained by utilizing those resources in an alternative way.
Opportunity costs play a significant role in production and inventory management
decisions. Here's a discussion of the importance of opportunity costs in inventory
management:
Capital and Storage Costs:
- Holding inventory ties up capital that could have been used for other productive
purposes, such as investing in new equipment, expanding operations, or funding research
and development.
- The opportunity cost of inventory includes the foregone interest or return on
investment that could have been earned if the capital was allocated elsewhere.
- Additionally, storing inventory incurs storage costs, including rent, utilities, insurance,
and labor. These costs represent the opportunity cost of using the space for other
purposes or investing in alternative resources.
Risk of Obsolescence and Depreciation:
- Inventory carries the risk of obsolescence and depreciation, particularly for products
with a limited shelf life or technological advancements.
- The longer inventory is held, the greater the risk of products becoming outdated or
losing value. The opportunity cost in this case is the potential loss in value or sales that
could have been avoided if inventory levels were reduced or better managed.
Opportunity Cost of Stockouts:
- Maintaining optimal inventory levels is crucial to meet customer demand and avoid
stockouts. A stockout occurs when a customer request cannot be fulfilled due to
insufficient inventory.
- The opportunity cost of stockouts includes potential lost sales, customer
dissatisfaction, and damage to the company's reputation.
- Diagrammatically, the cost of stockouts can be illustrated as a downward sloping
demand curve intersecting the supply curve at a point where inventory levels are
insufficient to meet customer demand.
Production Flexibility and Opportunity Cost:
- In production, maintaining excessive inventory levels can limit flexibility and agility.
Large inventory holdings may restrict the ability to introduce product changes, respond to
market demand shifts, or adopt new production methods.
- The opportunity cost in this case is the potential gain from being able to adapt quickly
to market changes, launch new products, or implement more efficient production
processes.
Time Value of Money:
- The time value of money is an essential concept in inventory management. It
recognizes that money today is worth more than the same amount of money in the future
due to its potential for earning interest or being invested.
- By holding inventory, a company ties up funds that could have been invested
elsewhere. The opportunity cost is the potential return or interest that could have been
earned during the holding period.
It's important for companies to consider these opportunity costs in inventory management
decisions. By optimizing inventory levels, balancing costs, and considering the
opportunity costs, companies can improve efficiency, reduce financial burdens, and
enhance profitability.

QUESTION 13
a) Potential locations Chinhoyi, Mutare and Marondera have the cost structures as shown below.
The Delta company has a demand of 130 000 units of a new product. Three potential
locations X, Y and Z having the following cost structures are available. Select which location
is to be selected and also identify the volume ranges where each location is suited [10 marks]
Fixed Costs
Variable
costs
Chinhoyi
$150 000
Mutare
$350 000
Marondera
$950 000
$10 000
$800 0
$6 000
To determine the optimal location for the Delta company based on the given cost structures, we
need to calculate the total cost for each location at the demand of 130,000 units. The total cost is
the sum of fixed costs and variable costs.
For location Chinhoyi:
Total Cost = Fixed Costs + (Variable Costs per Unit * Demand)
Total Cost = $150,000 + ($10,000 * 130,000) = $1,650,000
For location Mutare:
Total Cost = Fixed Costs + (Variable Costs per Unit * Demand)
Total Cost = $350,000 + ($8,000 * 130,000) = $2,750,000
For location Marondera:
Total Cost = Fixed Costs + (Variable Costs per Unit * Demand)
Total Cost = $950,000 + ($6,000 * 130,000) = $1,670,000
Based on the calculations, the total cost for Chinhoyi is $1,650,000, for Mutare is $2,750,000,
and for Marondera is $1,670,000.
Therefore, the optimal location for the Delta company would be Chinhoyi as it has the lowest
total cost among the three locations.
Now, let's identify the volume ranges where each location is suited based on their cost structures:
1. Chinhoyi:
Chinhoyi is suitable for volume ranges where the total cost of production at Chinhoyi is lower
than the total cost at the other locations. In this case, Chinhoyi would be suitable for a volume
range where the total cost of producing 130,000 units is the lowest compared to Mutare and
Marondera.
2. Mutare:
Mutare is suitable for volume ranges where the total cost of production at Mutare is lower than
the total cost at Chinhoyi and Marondera. In this case, Mutare would be suitable for a volume
range where the total cost of producing 130,000 units is lower than Chinhoyi but higher than
Marondera.
3. Marondera:
Marondera is suitable for volume ranges where the total cost of production at Marondera is lower
than the total cost at Chinhoyi and Mutare. In this case, Marondera would be suitable for a
volume range where the total cost of producing 130,000 units is higher than Chinhoyi but lower
than Mutare.
In summary, based on the given cost structures and the demand of 130,000 units, Chinhoyi is the
optimal location with the lowest total cost. However, the suitability of each location for different
volume ranges may vary depending on their cost structures.

QUESTION 14
Discuss the theory of constraints and how its assumptions can help to optimise production
operations [25 marks]
The Theory of Constraints (TOC) is a management philosophy and methodology developed by
Eliyahu Goldratt in the 1980s. It focuses on identifying and managing the constraints or
bottlenecks that limit the overall performance of a system. The theory assumes that every system
has at least one constraint that prevents it from achieving higher levels of performance, and by
effectively managing these constraints, organizations can optimize their production operations.
The theory of constraints is based on several key assumptions:
1. Every system has a constraint: The theory assumes that there is at least one constraint in any
system, whether it's a manufacturing process, a supply chain, or a service operation. A constraint
can be a physical limitation, such as a machine with limited capacity, or a non-physical
constraint, such as a policy or a skill gap.
2. The performance of the system is limited by the constraint: The theory states that the overall
performance of the system is determined by the performance of its constraint. Improving other
non-constraint areas of the system will not lead to a significant improvement in overall
performance if the constraint is not addressed.
3. Exploiting the constraint maximizes system performance: The theory emphasizes the
importance of exploiting the constraint by utilizing its full capacity. This involves identifying
ways to make the most effective use of the constraint, eliminating any non-value-added activities,
and ensuring that the constraint is never idle.
4. Subordination and synchronization are necessary: The theory advocates for subordinating nonconstraints to the constraint and synchronizing all activities to the pace of the constraint. This
means aligning the entire system's flow of materials, information, and resources to support the
constraint and prevent overburdening or underutilization of the constraint.
5. Elevating the constraint improves system performance: The theory suggests that elevating or
removing the constraint can lead to significant improvements in system performance. This can be
done through various methods such as investing in additional capacity, improving the constraint's
efficiency, or redesigning processes to eliminate the constraint altogether.
By following these assumptions, organizations can optimize their production operations using
the theory of constraints:
1. Identify the constraint: The first step is to identify the bottleneck or constraint in the system.
This can be done through data analysis, process mapping, and performance measurements. Once
identified, the constraint becomes the focus of improvement efforts.
2. Exploit the constraint: The next step is to exploit the constraint by maximizing its utilization.
This may involve streamlining processes, improving equipment reliability, or reallocating
resources to ensure the constraint is always working at full capacity.
3. Subordinate and synchronize: Non-constraint activities should be subordinated to the
constraint to prevent overburdening it. Synchronization ensures that all activities are aligned with
the pace of the constraint, preventing bottlenecks and imbalances in the system.
4. Elevate the constraint: If the constraint is still limiting system performance, efforts should be
made to elevate or remove it. This may involve investing in additional capacity, improving the
constraint's efficiency, or redesigning processes to eliminate the constraint.
5. Repeat the process: Once the initial constraint is addressed, the process is repeated to identify
and optimize the next constraint. This continuous improvement cycle ensures ongoing
optimization of production operations.
By applying the theory of constraints, organizations can improve throughput, reduce lead times,
increase productivity, and ultimately optimize their production operations. The theory helps
identify and focus on the most critical areas for improvement, leading to significant performance
gains and overall system optimization.

ultimately enhancing their production and value chain activities.
QUESTION 19
Discuss any 4 forms of productivity with related formulas and why firms need to measure
productivity of their respective operations
Four forms of productivity that firms can measure in their operations are labor productivity,
capital productivity, energy productivity, and total factor productivity.
1. Labor Productivity:
Labor productivity measures the output generated per unit of labor input. It provides insights into
the efficiency and effectiveness of a firm's workforce. The formula for labor productivity is:
Labor Productivity = Output / Labor Input
Firms need to measure labor productivity to assess the efficiency of their workforce and identify
opportunities for improvement. By tracking labor productivity, firms can identify areas where
additional training or process improvements are needed, optimize staffing levels, and enhance
overall operational efficiency.
2. Capital Productivity:
Capital productivity measures the output generated per unit of capital invested. It assesses how
effectively a firm utilizes its capital resources to produce goods or services. The formula for
capital productivity is:
Capital Productivity = Output / Capital Input
Measuring capital productivity helps firms evaluate the efficiency of their capital investments
and determine if they are generating sufficient returns. It allows firms to identify underutilized or
inefficient capital assets and make informed decisions regarding capital allocation and
investment strategies.
3. Energy Productivity:
Energy productivity measures the output generated per unit of energy input. It assesses how
efficiently a firm uses energy resources in its production processes. The formula for energy
productivity is:
Energy Productivity = Output / Energy Input
Measuring energy productivity is crucial for firms to identify opportunities for energy efficiency
improvements and cost savings. By monitoring energy productivity, firms can implement
energy-saving initiatives, adopt energy-efficient technologies, and optimize energy consumption
patterns, contributing to sustainability goals and reducing operating costs.
4. Total Factor Productivity (TFP):
Total factor productivity measures the overall efficiency of all inputs used in production,
including labor, capital, energy, and other resources. It represents the residual output not
accounted for by the individual productivity measures. The formula for TFP is:
Total Factor Productivity = Output / (Labor Input + Capital Input + Energy Input + Other Inputs)
Measuring TFP allows firms to evaluate their overall efficiency and assess the effectiveness of
their resource allocation. It helps identify areas of improvement in the utilization of various
inputs and supports decision-making processes related to resource allocation, process
optimization, and technological advancements.
Firms need to measure productivity in their operations for several reasons:
1. Performance Evaluation: Productivity metrics provide a basis for evaluating the performance
of different departments, teams, or processes within a firm. It enables firms to identify highperforming areas and areas that require improvement, leading to better resource allocation and
strategic decision-making.
2. Efficiency Improvement: Measuring productivity helps firms identify inefficiencies and
bottlenecks in their operations. By analyzing productivity metrics, firms can identify
opportunities to streamline processes, eliminate waste, and improve overall operational
efficiency.
3. Resource Optimization: Productivity measurements enable firms to optimize resource
allocation by identifying underutilized resources or areas with excess capacity. This helps in
allocating resources more effectively, reducing costs, and improving overall productivity.
4. Benchmarking and Comparison: Measuring productivity allows firms to benchmark their
performance against industry standards or competitors. It provides a basis for comparison and
helps firms identify areas where they lag or excel, enabling them to implement strategies to
improve their competitive position.
Overall, measuring productivity provides firms with valuable insights into their operational
efficiency, resource allocation, and performance. It helps firms make informed decisions, drive
continuous improvement, and enhance their competitive advantage in the marketplace.
