  1. CHAPTER 10SUPPLY CHAIN STRATEGY

  2. Supply Chain Strategy • Supply chain management • Competitive advantage • Aligning product and supply chain strategy

  3. Supply Chain • A supply chain represents all the stages at which value is added in producing and delivering a product or service from suppliers (and their suppliers) to customers (and their customers).

  4. Supply Chain Management • Supply chain management is the coordination of the following functions and activities along the supply chain: • Planning and managing of supply and demand • Acquiring material • Warehousing • Inventory control and distribution • Producing and scheduling the product or service • Delivery and customer service

  5. Supply Chain Database and Planning

  6. Supply Chain Management and Competitive Advantage • Competitive advantage may be obtained with a total systems approach to managing flow of information, materials and services along the supply chain

  7. Investment in Supply Chain • High profit margin (high tech products) • Reduce stockout • Invest in reducing lead time along the supply chain • Low profit margin (staple products) • Reduce cost • Increase resource utilization, minimize inventory, • select vendors on the basis of cost and quality, design products that can be produced

  8. Matching Supply Chain with Products Functional Products Innovative Products Efficient Supply-Chain Match Mismatch Responsive Supply-Chain Mismatch Match

  9. CHAPTER 11STRATEGIC CAPACITY MANAGEMENT

  10. Strategic Capacity Management • Capacity • Planning issues • Capacity additions • Determining capacity requirements

  11. Capacity • Output over a certain time period • Peak? Average? Design capacity? • Best operating level • Design capacity, minimum average cost • Capacity utilization

  12. Planning Issues • Economies and Diseconomies of scale • Advantage and disadvantage of capacity • Learning curve • Another advantage of capacity • Focussed factories • A strategy to remove the disadvantage of capacity • Capacity flexibility • A strategy to deal with demand uncertainty

  14. Learning Curve • An example of 80% learning curve • 1st unit 100 hours • 2nd unit 80 hours • 4th unit 64 hours Processing time per unit Units produced

  15. Learning Curve Yx= Kxn where • x = Unit number • Yx= time required for the xth unit • K = time required for the first unit • n = log b/log 2, where b is the percentage rate of improvement

  16. Learning Curve Contract to produce 35 computers • K = 18 hours • Learning rate = 80% • What is time for the 9th unit? 35 units? Y9 = (18)(9)log(0.8)/log(0.2) = (18)(0.493) (See Exhibit TN4.5, p. 138) = 8.874hrs Y1+…+Y35 = (18)(15.64) (See Exhibit TN4.6, p. 139) = 281.52hrs

  17. Focussed Factories • Theory • A production facility is the most efficient when it concentrates on a fairly limited set of tasks objectives • An implication • Instead of building one huge plant, build several smaller plants • An example • Plant 1: Production of components • Plant 2: Assembly

  18. Capacity Flexibility: Flexible Workers Machines Enter Worker 2 Worker 3 Worker 1 Exit Key: Product route Worker route

  19. Capacity Flexibility: Flexible Machine • Many tools in the tool magazine • Tools are changed instantaneously • Thus, products with different designs are produced without long setup times A CNC Hobbing Machine

  20. Capacity Additions • Maintaining system balance • Frequency of capacity additions • Too frequent: installation, training, premium for up to date technology, loss of production time • Too infrequent: cost of excess capacity • External sources of capacity • Subcontracting • Capacity sharing

  21. To customers To customers Inputs Inputs 1 2 3 1 2 3 200/hr 200/hr 200/hr 200/hr 200/hr 50/hr (b) All operations bottlenecks (a) Operation 2 a bottleneck Maintaining System Balance

  22. Capacity Expansion Strategies Lead strategy Lag strategy Capacity Units Units Demand Time Time Add average Units Demand Time

  23. Determining Capacity Requirements • Estimate capacity requirements • Identify gaps • Develop alternatives • Evaluate the alternatives • Decision tree is a tool used to evaluate alternatives

  24. A Decision Tree Example Text Chapter 11 Problem 5 • Expando Inc. is considering the possibility of building a facility. • Small facility: costs $8 million. If demand is low, revenue will be $10 million. If demand is high revenue will be $12 million. • Large facility: costs $9 million. If demand is low, revenue will be $10 million. If demand is high revenue will be $14 million. • The probability of demand being high is 0.40 and the probability of it being low is 0.60 • Not constructing a new facility would not generate any additional revenue.

  25. Build the small facility with expected value = $2.8 million

  26. Reading and Exercises • Chapter 10 (Supply Chain Strategy) • up to p. 413 • Chapter 11 (Strategic Capacity Management) • up to p. 440 • Problem 6 • Technical Note 4 (Learning Curves) • up to p. 141 • Problems 1,4
