Assume that weekly demand for phones at B&M Office Supplies is normally distributed, with a mean of 2,000 and a standard deviation of 500. it takes two weeks to fill an order placed by the B&M. The store manager orders 10,000 phones when the inventory drops to 6,000; that is, a reorder point is 6,000.
(1) What is the average inventory of B&M? (average inventory = average cycle inventory + average safety inventory)
(2) What is the Cycle Service Level(CSL)? (Hint: Use the normal distribution table attached. Use approximation when using the table.) Note that CSL=Probability(demand during the lead time <= Reoder Point)
