to Introduction Production and Manufacturing Systems 05/19/09 2006 Prentice Hall, Inc. ISEN 220 Texas A&M Industrial Engineering 1 16 1 Newsvendor Model Unlike the EOQ model, the newsvendor model: 1. allows demand to be random, 2. is a one-period model, i.e., we make a oneshot decision 2006 Prentice Hall, Inc. 16 2 Newsvendor Model No re-stocking allowed. Discussion: How restrictive is the one-period assumption? 2006 Prentice Hall, Inc. 16 3 Newsvendor Model Define the following notation: Q = number of units stocked in the beginning of the period. D = demand, a random variable. co = overage cost, i.e., cost per unit remaining in inventory at the end of the period. cu = underage cost, i.e., cost per unit of unsatisfied demand. F(x) = cumulative distribution function for D, i.e., P(D x) 2006 Prentice Hall, Inc. 16 4 Newsvendor Model Why not just stock exactly enough to satisfy the mean demand? 2006 Prentice Hall, Inc. 16 5 Newsvendor Model How much should we stock in optimality? 2006 Prentice Hall, Inc. 16 6 Newsvendor Model 2006 Prentice Hall, Inc. 16 7 Newsvendor Model 2006 Prentice Hall, Inc. 16 8 Newsvendor Example 2006 Prentice Hall, Inc. 16 9 Supply Chain Management What is a Supply Chain? Network of entities: Suppliers (and their suppliers) Manufacturers of semi-finished and finished products Distributors Customers 2006 Prentice Hall, Inc. 16 10 2006 Prentice Hall, Inc. 16 11 The Strategic Importance of the Supply Chain Supply-chain management is the integration of the activities that procure materials and services, transform them into intermediate goods and the final product, and deliver them to customers Competition is no longer between companies; it is between supply chains 2006 Prentice Hall, Inc. 16 12 A Supply Chain -- Beer Figure 11.1 2006 Prentice Hall, Inc. 16 13 Supply Chain Flows Downstream flows: Upstream flows: 2006 Prentice Hall, Inc. 16 14 Integration of Suppliers: Volkswagen Brazil Brazilian plant employs 1000 workers 200 work for VW and are responsible for overall quality, marketing, research, and design 800 work for other contractors and do the assembly work 2006 Prentice Hall, Inc. 16 15 Volkswagen Brazil Important elements of this concept VW is buying not only materials, also but the labor and related services Suppliers are integrated tightly into VW's own network, right down to assembly work in the plant Purchase costs in the auto industry exceed 60% of the sales dollar, so any savings are significant 2006 Prentice Hall, Inc. 16 16 Volkswagen Brazil 2006 Prentice Hall, Inc. 16 17 Supplier Relationships Negotiating with many suppliers Long-term partnering with few suppliers Vertical integration 2006 Prentice Hall, Inc. 16 18 Many Suppliers Commonly used for commodity products Purchasing is typically based on price Suppliers are pitted against one another 2006 Prentice Hall, Inc. 16 19 Few Suppliers Buyer forms longer term relationships with fewer suppliers Create value through economies of scale and learning curve improvements 2006 Prentice Hall, Inc. 16 20 Vertical Integration Vertical Integration Raw material (suppliers) Iron ore Examples of Vertical Integration Silicon Farming Backward integration Steel Current transformation Automobiles Integrated circuits Flour milling Forward integration Distribution systems Circuit boards Finished goods (customers) 2006 Prentice Hall, Inc.
