Warehousing Terms
SKU – Stock Keeping Unit Product in (packaged) form for warehouse operations
Value-Added A modification to the product to obtain business
(a product enhancement from the customer’s perspective or an enhancement to the customer’s experience in getting the item)
Cross-Docking Transforming incoming product to outgoing product without
moving the product to production or storage Spotting
Locating and positioning a carrier vehicle within the loading / unloading areas of the facility
ASN – Advance Shipping Notice Information about a shipment sent from the shipping firm to the
receiving firm, directly through EDI (electronic data interchange)

Warehousing Metrics
Order-picking Improvement Productivity Improvement Space Utilization Improvement Value-Added Improvement Safety Improvement
Personnel & Equipment Cargo
Most plants do not make their money in the warehouse… For some, the warehouse IS the plant!
Distribution centers (Target, x-Mart; grocers; airports; …)Shipping businesses (Fed Ex, UPS; shipping ports; movers; …)

Receiving Operations
All or a subset of the following sequence:1. Inbound delivery scheduling and information exchange2. ASN verification and confirmation3. Delivery arrival and spotting4. Vehicle secured at the receiving dock5. Seal inspection / breaking6. Initial delivery inspection – accepted / refused7. Merchandise unloaded (unitized or loose)8. Unloaded material is staged for final inspection9. Determination & disposition of carrier damage10. Load storage & over-pack disposal activities

Shipping Operations
All or a subset of the following sequence:1. Order accumulation & packing
2. Order staging for loading / labeling & out-going inspection / counting
3. Customer order & shipping release reconciliation
4. Spotting carrier to a dock
5. Securing carrier vehicle at dock
6. Loading vehicle
7. Dispatching the vehicle

Shipping & Receiving Analysis
Analysis of requirements for: What is to be received and shipped
Peak product volumesTiming of peaks, and growth
How many docks to be plannedCarrier vehicle quantitiesTiming of arrivals & departures
What kinds of dock equipment to be usedCarrier vehicle types and variantsEnvironmental conditions for loading / unloading
How much space is required for shipping and receiving activitiesSKU container volumesShipping debris volumesMaterial handling equipment spaceCarrier vehicle dock access and spotting spaceCarrier personnel space

Truck Access
Service roads should be at least 24 ft wide if two-directional, and at least 12 ft wide if the road is one-directional
Add at least 4 ft to the road width if gate openings are needed
Provide a 4 ft wide walk, physically removed from the road, if pedestrian traffic is required along service roads
Increase gate openings by 6 ft if pedestrians will pass through
Right angle intersections should have at least a 50 ft radius
Prefer counterclockwise traffic circulation because left turns are safer than right turns** (UPS study suggests right turns!)
Truck waiting areas should be designed to hold the maximum expected number of trucks, and should be located adjacent to the dock apron

90o Apron Space
Aprons are space allotted for spotting a vehicle – maneuvering room to align with the dock
04/19/23 IENG 471 Facilities Planning 12
Angled Apron Space (Finger Docks)
Angled Aprons allow for access to tighter spaces

Material Handling Equipment Space
MHE SpaceIs in addition to staging, storage, dock, and personnel space; and allows for maneuvering the MHE vehicle …

Design of Warehousing Space
Similar to design of the rest of the facility:Efficiency of space utilization should not
detract from the function of the facilityStorage space may be allocated similar to
production spacePareto principal (80/20 Rule)Group Technology applies
Information Systems improve picking operations
