The Role of Distributionin 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

Distribution directly affects cost and the customer experience and therefore drives profitability

Choice of distribution network can achieve supply chain objectives from low cost to high responsiveness

Examples: Wal-Mart, Dell, Proctor & Gamble, Grainger

4

Factors InfluencingDistribution Network Design

Distribution network performance evaluated along two dimensions at the highest level:– Customer needs that are met

– Cost of meeting customer needs

Distribution network design options must therefore be compared according to their impact on customer service and the cost to provide this level of service

5

Factors InfluencingDistribution Network Design Elements of customer service influenced by network structure:

– Response time– Product variety– Product availability– Customer experience– Order visibility– Returnability

Supply chain costs affected by network structure:– Inventories– Transportation– Facilities and handling– Information

The Value of Distributorsin the Supply Chain

Distributing Consumer Goods in India Distributing MRO Products Distributing Electronic Components

22

Distribution Networks in Practice

The ownership structure of the distribution network can have as big as an impact as the type of distribution network

The choice of a distribution network has very long-term consequences

Consider whether an exclusive distribution strategy is advantageous

Product, price, commoditization, and criticality have an impact on the type of distribution system preferred by customers

23

Summary of Learning Objectives

What are the key factors to be considered when designing the distribution network?

What are the strengths and weaknesses of various distribution options?

What roles do distributors play in the supply chain?

Network Design Decisions

Facility role- flexibility of Toyota since 1997

Facility location- Amazon.com : a single warehouse in Seattle

Capacity allocation- Allocating too much poor utilization

- Allocating too little poor responsiveness, high cost

Market and supply allocation- Amazon.com : built new warehouses due to grown markets

26

Factors Influencing Network Design Decisions

Strategic – Cost vs. Responsiveness

ex) Apparel producers, Convenience stores, Discount stores

Technological – Economies of scale few high-capacity locations

ex) Manufacturer of computer chips

– Lower fixed costs many local facilities

ex) Bottling plants for Coca-Cola

Macroeconomic– Tariffs, Tax incentives, Exchange rate and Demand risk

Political

27

Factors Influencing Network Design Decisions (continued)

Infrastructure – availability of sites & labor

– proximity to transportation terminals, rail service, airports and seaports

– highway access, congestion, local utilities

Competitive – Close vs. Far

ex) Retail stores in a mall, Supermarkets

Logistics and facility costs

Network Optimization Models

Allocating demand to production facilities Locating facilities and allocating capacity

Which plants to establish? How to configure the network?

Key Costs:

•Fixed facility cost•Transportation cost•Production cost•Inventory cost•Coordination cost

37

Demand Allocation Model

Which market is served by which plant?

Which supply sources are used by a plant?

xij = Quantity shipped from plant site i to customer j

Capacity Investment Strategies

Speculative Strategy– Single sourcing

Hedging Strategy– Match revenue and cost exposure

Flexible Strategy– Excess total capacity in multiple plants– Flexible technologies
