1
Role of Distribution in the Supply Chain
 Distribution
 The steps taken to move and store a product from the supplier
stage to the customer stage in a supply chain
 Affecting the cost and the customer experience, and therefore
driving profitability
• Efficiency vs. responsiveness
 Different choice for similar distribution
 Examples
• Wal-Mart, Seven-Eleven Japan, Webvan
• Dell, Gateway, Apple
• Proctor & Gamble
 Terms
 SKU, truckload (TL), less-than-truckload (LTL), package-load
 Inventory turnover, fast-moving, slow-moving
2
Factors Influencing Network Design
 Dimensions for evaluating network performance
 Customer needs that are met
 Cost of meeting customer needs
 Tradeoff
 customer service vs. cost to provide this level of service
 Customer service influenced by network structure
 Response time
 Product variety
 Product availability
 Customer experience
 Order visibility
 Returnability

Design Options for Distribution Network
 Two key decisions
 Delivered or customer pickup?
 Intermediate locations or not?
 Classification

Retail storage with customer pickup
Manufacturer storage with direct shipping
Manufacturer storage with direct shipping and in-transit merge
Distributor storage with carrier delivery
Distributor storage with last-mile delivery
Manufacturer or distributor storage with customer pickup
and others

Design Options for Distribution Network
 Retail (manufacturer) storage with customer pickup
Suppliers/distributers
Retailers (manufacturers)
Customers

Design Options for Distribution Network
 Manufacturer storage with direct shipping (cont’d)
 Characteristics
• Slow-moving items
• Mixed with other type of networks for fast-moving items
• Aggregation
• Ownership structure of inventory at manufacturers
• Postponement and customization
• Build-to-order
• Usually employing package carriers
 Performance
• Inventory, transportation, facilities and handling, information
• Response time, product variety, product availability, customer
experience, time to market, order visibility, returnability
 Best for low-demand and high-value items, customers who are
willing to wait for delivery and accept several partial shipment

10
Design Options for Distribution Network
 Manufacturer storage with direct shipping and in-transit
merge (cont’d)
 e.g., Dell + Sony
 Using package carrier
 Very sophisticated information infrastructure
11
Design Options for Distribution Network
 Distributor storage with carrier delivery
Factories
Warehouse Storage by
Distributor/Retailer
Customers
Product Flow
Information Flow
12
Design Options for Distribution Network
 Distributor storage with carrier delivery (cont’d)
 e.g., Amazon
 Slow-moving items in factories, fast-moving items in warehouse
13
Design Options for Distribution Network
 Distributor storage with last mile delivery
Factories
Distributor/Retailer
Warehouse
Customers
Product Flow
Information Flow
14
Design Options for Distribution Network
 Distributor storage with last mile delivery (cont’d)
 e.g., Webvan, Peapod, Albertson, automotive spare parts
industry
 More warehouses are required (need to be close to customers)
 Higher transportation cost
• Package carriers can aggregate delivery across retailer.
• Less expensive in large, dense cities
• Best if large quantity purchasing
 Processing cost
• Much higher because all customer participation is eliminated
• Higher labor cost
 Information handling
• Scheduling

Distribution Networks in Practice
 Ownership structure of distribution network
 As big an impact as the type of distribution network
• e.g., a 3PL who pursuits its own profit
 Long-term consequences of choice of network type
 e.g., car dealers
 Exclusive distribution strategy or not
 Customer preference on network type
 Product price, commoditization, criticality
 Integration of Internet and existing physical network
