1. Weekly demand for Motorola cell phones at a Best Buy store is normally distributed, with a mean of 300 and a standard deviation of 200. Motorola takes two weeks to supply a Best Buy order. Best Buy is targeting a CSL of 95 percent and monitors its inventory continuously. How much safety inventory of cell phones should Best Buy carry? What should its ROP be?
2. Reconsider the Best Buy store in Exercise 1. The store manager has decided to follow a periodic review policy to manage inventory of cell phones. She plans to order every three weeks. Given a desired CSL of 95 percent, how much safety inventory should the store carry? What should its OUL be?
3. Assume that the Best Buy store in Exercise 1 has a policy of ordering cell phones from Motorola in lots of 500. Weekly demand for Motorola cell phones at the store is normally distributed, with a mean of 300 and a standard deviation of 200. Motorola takes two weeks to supply an order. If the store manager is targeting a fill rate of 99 percent, what safety inventory should the store carry? What should its ROP be?
4. Weekly demand for HP printers at a Sam’s Club store is normally distributed, with a mean of 250 and a standard deviation of 150. The store manager continuously monitors inventory and currently orders 1,000 printers each time the inventory drops to 600 printers. HP currently takes two weeks to fill an order. How much safety inventory does the store carry? What CSL does Sam’s Club achieve as a result of this policy? What fill rate does the store achieve?
