Demand is variable and the company wants to build a safety stock into R. If the average daily demand is 15 , the lead time is 5 days, the desired z value is 1.96 , and the standard deviation of usage during lead time is 3 , which of the following is the desired value of R ? About 61 About 76 About 81 About 66 About 89 A Company currently has 230 units of a product on-hand that it orders every three weeks when the salesperson visits the premises. Average demand for the product is 20 units per day with a standard deviation of 5 units. Lead time for the product to arrive is seven days.

The reviewer period is 14 days and the lead time is 7 days. At the time of the review, 140 units are in stock. If only a 2 percent of stocking out is acceptable, how many units should be ordered. 2730 2710 2648 2823 2872 In a single-period Newsvendor model, if the demand is normally distributed with a mean of 80 and a standard deviation of 10 , and the optimal service level is 90%, what is the optimal order quantity? 90 87 100 93 103
