Suppose the weekly demand for a popular tablet computer follows the normal distribution N(Mean, Standard Deviation) given as: N(1500, 200) in UK N(2000, 250) in Germany N(1200, 200) in France. Amazone sources the tablet at $250 per unit, and the sourcing lead time is 2 weeks. Each sourcing order costs Amazone $200 in administrative processing and transportation. Amazone uses a continuous review (Q, R) (order Q when the inventory reaches R) policy to manage inventory and targets a 98% service level (z = 2.054). Assume an annual interest rate of 50% to calculate inventory holding cost and 52 weeks in a year. a) What are order quantity Q and reorder point ROP R for each DC? OPERATIONS & TECHNOLOGY MANAGEMENT PAGE 2 b) Define Cycle Stock as Q/2 and Safety Stock as R minus the expected demand during lead time, and the average inventory as the sum of cycle stock and safety stock. What is the total amount of average inventory held in all three DCs? c) If Amazon uses one single DC to serve the tablet demand in all three countries, what are the resulting Q, and R, and average inventory held in the DC? How many units of inventor
