Using the information in Problem 2, compute the planned order releases using part-period balancing where the ratio of setup cost to the holding cost is 200.

1. Suppose an assembly requires five components from five different vendors. To guarantee starting the assembly on time with 90 percent confidence, what must the service level be for each of the five components? (Assume the same service level for each component.) 2. End item A has a planned lead time of 2 weeks. There are currently 120 units on hand and no scheduled receipts. Compute the planned order releases using lot-for-lot and the MPS shown here: Week 2 3 4 5 6 7 8 9 10 Demand 41 44 84 42 84 86 7 18 49 30 3. Using the information in Problem 2. compute the planned order releases using part-period balancing where the ratio of setup cost to the holding cost is 2001 4. (Challenge) With the information in Problem 2, compute the planned order releases using Wagner-Whitin, where the ratio of setup cost to holding cost is 200. How much lower is the cost of the plan than in the previous case? 5. Rework Problem 2 with 50 units of safety stock. What is different from Problem 2? 6. Rework Problem 2 with a planned lead time of two periods and a safety lead time of one period. What is different from Problem 2? 7. Suppose demand for a power steering gear assembly is given by
