Introduction Progression of Warehousing Decisions Why Use Warehouses? Types of Warehousing Warehouse Operations Warehousing Innovations Warehouse Layout Packaging
Progression of Warehousing Decisions. Should Warehouses Be Used? If Warehouses are Used, Should they be Public or Private? Where Should they be Located? What Should be their Capacities? How Many Should You Have? What Should be their Layout and Design?
Why Use Warehouses? Cope with Variable Market Conditions Cope with Variable Sources of Supply Production Economies Purchasing Economies Transportation Economies Customer Service

Private vs Public Warehousing (Without Cost of Capital) Public $ (All Variable Cost) Private (Fixed + Variable Cost) Prefer Public Indifferent Prefer Private Volume
(Without Cost of Capital) Indifference Point Between Public and Private (Without Cost of Capital) Private = Fixed Costs + Variable Costs Public = Variable Costs Example: Private Fixed Costs = $500,000/year Private Variable Costs = $0.15/pound Public Variable Costs = $0.25/pound Indifference point is where both costs are equal 500,000 + .15X = .25X 500,000 = .10X X = 5,000,000 pounds ROI = 0
Private vs Public Warehousing (With Cost of Capital) $ Public Savings (All Variable Cost) Private (Fixed + Variable Cost) Prefer Public Indifferent Prefer Private Volume
Indifference Point Between Public and Private (With Cost of Capital) Private = Fixed Costs + Variable Costs Public = Variable Costs Example: Private Fixed Costs = $500,000/year Private Variable Costs = $0.15/pound Public Variable Costs = $0.25/pound Indifference point is where savings = desired ROI Savings Average Investment = ROI
Indifference Point Between Public and Private (With Cost of Capital) Desired ROI = Hurdle Rate Savings = Public – Private Average Investment = Initial Investment /2 Example: Hurdle Rate = 10% Investment = $8,000,000 Private Fixed Costs = $500,000/year Private Variable Costs = $0.15/pound Public Variable Costs = $0.25/pound
Indifference Point Between Public and Private (With Cost of Capital) Hurdle Rate = 10% Investment = $8,000,000 Private Fixed Costs = $500,000/year Private Variable Costs = $0.15/pound Public Variable Costs = $0.25/pound Savings = Public - Private .25X - (500,000 + .15X) 4,000,000 = .10
Indifference Point Between Public and Private (With Cost of Capital) Savings = Public – Private .25X - (500,000 + .15X) 4,000,000 = .10 .25X - (500,000 + .15X) = .10 * 4,000,000 .25X - 500,000 - .15X = 400,000 .25X - .15X = 400,000 + 500,000 .10X = 900,000 X = 9,000,000
Advantages of Private Warehousing Greater Control Flexibility (CS Needs, Space Use, etc.) Tax Benefits (Depreciation) Image to Customers Potentially Lower Cost
Disadvantages of Private Warehousing Lack of Flexibility (Fixed Size/Location) Capital Requirements Equipment Maintenance/Training Potential Labor Problems
Advantages of Public Warehousing Capital Conservation Ability to Meet Peak Demand Reduced Risk Flexibility WRT Volume Avoidance of Property Taxes Avoidance of Labor Problems Potentially Lower Cost Knowledge of Exact Costs
Disadvantages of Public Warehouses Lack of Control Difficult Communications Not Always Available Potentially Higher Cost
Cross-Docking An operations procedure that allows product to be delivered and received on one side of a facility, undergoes internal handling procedures at the receiving dock, distributing unit loads and moving the product to shipping docks on the other side of the facility where trucks or rail cars are waiting to be loaded for customer delivery.

Postponement What is it? Why do we do it? Examples
Postponement What is it? A delayed differentiation strategy to reduce uncertainty and cost while satisfying customer needs. Activities in the supply chain are delayed until a demand is realized. Bucklin (1965) Model of Postponement /Speculation
Postponement Why do we do it? It has the potential to improve responsiveness while reducing inventory, transportation, storage, and obsolescence. Insufficient inventory early in the product cycle can cost market share. Products at the end of life cycle lose value quickly and risk obsolescence, which can lead to large inventory write-offs.
