question #2 Same problem statement: Weekly demand for DVD-Rs at a retailer is normally distributed with a mean of 1,000 boxes and a standard deviation of 150. Currently, the store places orders to the supplier, with a reorder point of 4,200 boxes. The order quantity to the supplier is fixed at 5,000 boxes.

Dev. of Demand:125 per week Lead time:14 days a) Ignoring the uncertainty in the demand (i.e. looking only at average values), find the optimal order quantity and the reorder point. b) Consider now the uncertainty. The order quantity remains the same. If the target is to have a 98% annual service level, what should be the ROP? What is the safety stock? c) If the ROP is 1178 units (note that z value has been changed), what is the corresponding annual service level that the firm can provide?
