Warehouse orders for completeness. • Carriers must be properly considered for these operations along with the activities of carriers. Facility Planning Goods receiving process: • Inbound trucker contacts the warehouse to get a delivery appointment and provides information about the cargo. • Warehouse officer verifies the advance shipping notice (ASN) and • confirms it with received note by phone from the trucker. • Trucker arrives and is assigned to a specific receiving door. • Vehicle is safely secured at dock. • Seal is inspected and broken in presence of carrier representative. • Load is inspected and either accepted or refused. • Unitized merchandise is unloaded. • Floor-loaded or loose merchandise is unloaded. • All unloaded material is staged for count and final inspection. Warehouse • Proper disposal is made of carrier damage. Facility Planning The facility requirements to perform the receiving activities include the following: • A proper area to stage and spot carriers. • Dock levelers and locks to facilitate carrier unloading. • Sufficient staging area to palletize or containerize goods. • Suitable area for ready dispatch goods . The required to ship include the • Aactivities good system for orders reportgoods generation. following: • Accumulate and pack the order. • Check & prepare the order. • Settle the customer order. • Place the carrier at secure dock. • Prepare dock levelers and locks. • Load & Dispatch the carrier.

Instead of being placed in storage, you prepare for delivery as fast as products arrive. 7- Sort inbound materials for efficient putaway. 8- Combine putaways and retrievals when possible This technique is especially geared for pallet storage mean that the incoming cargo is analyzed and checked 5-Stage in storage locations If material has to be staged, the floor space required for staging can to match the purchase receipt. be minimized by providing storage locations for receiving staging. Storage spaces over dock doors may be a good option. 3-Cross-dock , the fastest, most productive receiving and-retrieval operations. process is cross-docking—and the simplest kind of receipts to off-peak hours. cross-docking activity is one in which an entire inbound load is sorted and then reloaded onto one or more outbound vehicles. 6-Preparation the goods for shipping -Prepackage goods. -Apply labeling and tags. -Cube and weigh for storage and transport planning. 9- Balance the use of resources at receiving by scheduling carriers and shifting time-consuming 10- Minimize or eliminate walking by flowing inbound in workstations. Facility Planning Shipping Principles Including direct loading best-practice principles for unitizing and securing loads, automated loading, and dock management. 1-Select cost- and space-effective handling units. 2-Minimize product damage. 3-Eliminate shipping staging and direct-load outbound trailers. 4-Use storage racks to minimize floor-space requirements. 5-Use new system to Improve the management of shipping and receiving docks. 6-Use small-parcel shipping. Warehouse Facility Planning RECEIVING & SHIPPING SPACE PLANNING The steps required for determining space requirements for warehouse operations are: Determine what is to be received and shipped Determine the number and type of docks Determine the space requirements for receiving and shipping area within the facility. Warehouse Facility Planning What is to be received and shipped Implies information regarding what, when and how much of the items shipped or received. 1-5: Define what is to be received or shipped. 6: Size of shipment. 7: When the receipts and shipments will occur. 8-9: List the types of carriers. 10-11: Handling methods & time required for loading/unloading. Warehouse Facility Planning Identification of carrier types used for shipping and receiving What is including to be received and shipped the carrier height width and length also with the the dock. To determineheight the dockofheight, find the midpoint of the bed heights of the expected trucks. Most trucks require a dock height of between 46 and 52 in. See the Table for dock heights that create level docks for common types of trucks. Type of Truck Dock Height Container 55 in. Semitrailer 48 in. Straight Truck 44 in. Refrigerated 52 in. Flatbed 52 in.

If the arrival and service distribution are not much varied over time then waiting line analysis helps addressing the problems of number. If the arrival and service distribution vary over time then simulation technique will be used. By type of dock we mean configuration, which has to be determined after determining the no. of docks. It considers the flow of carriers relative to the facility. For rail docks configuration of the railroad spur dictate the flow of railroads thus leading to configuration of rail dock For truck docks traffic patterns of trucks must be Warehouse analyzed Facility Planning Waiting line analysis Facility Planning Receiving and Shipping Docks Central Dock (single dock for both receiving and shipping) Common equipment and personnel Better space utilization Higher incidence of space congestion Greater risk of material loss Error in material flow direction, e.g. shipping out a newly- received part by mistake Point-of-use Dock (multiple docks for receiving or shipping) Dedicated function, e.g. receiving frequent deliveries from Warehouse light-duty carriers or shipping specific category of goods Often used to support Just-in-Time (JIT) manufacturing set-ups Usually requires more space than central docking Facility Planning Warehouse Dock Configurations: 90° Dock Docks are among the first requirements at a site and are vital for smooth operations. Dock width that is commonly adopted is 12 feet. For highly busy docks, width of 14 feet is employed. Requires greater apron space but less bay width Larger outside turning area for carriers Commonly used when outside space is sufficient Warehouse 90° Dock Facility Planning Warehouse Dock Configurations: Finger Dock (Sawtooth) Requires lesser apron space but more bay width Bigger inside maneuvering area for carriers Used when there is insufficient apron space to support 90o dock The largest finger dock angle possible should be selected Finger Dock (Sawtooth) Warehouse Facility Planning Plan On-site Traffic Patterns Design the traffic patterns around the building so that the truck driver is on the inside of each turn, for best control of the truck. • One-way access roads that are 13 ft wide minimum. • Two-way access roads that are 26 ft wide minimum. Efficient truck traffic : • An entrance driveway that • Separate roads for employee traffic. • Truck waiting areas near the loading docks to accommodates the turning radius of the longest truck expected and allows trucks to be driven forward onto the site, rather than backed up. Truck movement counterclockwise. • Right-angle turns onto the site that have a minimum inside radius of 26 ft and a minimum outside radius of 50 ft. Warehouse accommodate all waiting trucks. Facility Planning Design the Apron Space Apron space is the space between the loading platform and the nearest obstruction. which is the area the truck uses to maneuver in and out of the parking area. The recommended center distance between dock positions is 12 ft minimum. Warehouse Determining shipping area requirement Receiving and shipping department area requirements within a facility may include space allocations for the following: Personnel convenience/office A receiving hold area Trash disposal and recycling bins Palletizing equipment The truckers lounge Buffer or staging areas Material handling Warehouse Facility Planning Facility Planning Dock Operations Planning Dock operation planning deals with equipment requirements for shipping and receiving which comprise of equipment suitable between The equipment are: carriers and docks. Dock levers (Between a dock at given height and carriers of variable height) Bumper pads (Between a fixed dock and a movable carrier) Dock shelters (Between a heated dock and unheated carrier) Dock leveler A dock leveler is a fixed bridge designed to permit the safe and efficient flow of goods into and out of a building. In order to accomplish this, a dock leveler must be able to support extremely heavy loads, service a wide range of truck heights, and compensate for tilted trucks. There two basic types of dock levelers based on the method of activation. Warehouse Facility Planning Dock Operations Planning Dock bumpers Each dock must be equipped with a form of dock bumper to protect the building from vehicle impact damage. Keep in mind that an approaching vehicle can generate up to 300,000 lbs. of impact force. Several styles of bumper are available to suit application requirements. For typical level approach applications, bumper projection should be specified at not less than 4". The two most common styles of bumpers are molded rubber and laminated rubber. Warehouse Facility Planning Dock Operations Planning Vehicle restrictions In a busy shipping area, there can be up to 100 opportunities per day, per single loading dock, for the most serious forklift accident to occur. It happens at the best of loading docks. Vehicle creep. Unscheduled truck departures. parking. TheCareless most common style of vehicle restraint is a face-mount design. Face mount restraints have four main functions: Prevent premature trailer departure. Limit trailer creep away from the dock. Restrict trailer movement to keep the extended lip of the dock leveler in place on the floor of the trailer. Prevents trailer theft. Warehouse Facility Planning Dock Operations Planning Dock shelter The purpose of installing dock seals or shelters is to maintain the internal climate of the facility and protect against product damage. Use of these products has many benefits such as: Energy Loss Savings - Reduces heating and cooling costs by maintaining interior temperature control. Safe Working Conditions - Keeps weather out; eliminates rain, ice and snow from loading areas, improving dock safety. Merchandise Protection - Protects valuable products against damaging heat, cold, rain, snow and wind. Minimizes vermin Warehouse entry. Facility Planning DOCK LOCATIONS Shipping docks and receiving docks can be combined, with shipping and receiving together (Figure 1), or they can be separated, with shipping and receiving in different areas of the building (Figure 2). Choose the loading dock location based on the Warehouse needs of the in-plant process. A combined dock works well in smaller buildings where shipping and receiving is infrequent. However, this design may increase in-plant traffic and travel distance. A separated dock works well in buildings where the materials enter production in one part of the building and the production is completed elsewhere. This design minimizes transportation of materials inside the building finally The Quality Of Your Work, in the Long Run, is the deciding factor on how much Your Services are valued by the WORLD.
