INVENTORY DECISIONS - VARIABLE DEMAND Given this information: i. Expected demand during lead time =600 units. ii. Standard deviation of lead time demand =60 units. Determine each of the following, assuming that lead time demand is distributed normally: a. The safety stock needed to attain a 1 percent risk of stockout during lead time. b. The reorder point (ROP) that will provide a risk of stockout of 1 percent during lead time. c. Would a stockout risk of 2 percent require more or less safety stock than a 1 percent risk? d. Would the ROP be larger, smaller, or unaffected if the acceptable risk was 2 percent instead of 1% ? Explain
