Weekly demand for Hewlett Packard 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 a thousand printers each time the inventory drops to 600 printers. Hewlett Packard currently takes two weeks to fill an order. How much safety inventory does the store carry? What cycle service level does Sam's Club achieve as a result of this policy? What fill rate does the store achieve? Now assume that the supply lead time from HP is normally distributed with a mean of 2 weeks and a standard deviation of 1.5 weeks. How much safety inventory should Sam's Club carry if they want to provide a cycle service level of 95 percent? How does the required safety inventory change as the standard deviation of lead time is reduced from 1.5 weeks to zero in intervals of 0.5 weeks?
