C. Problem Solving. 1. (20 points) A store uses a (QR) inventory system to control its stock levels. For a particular part, historical data show that the distribution of monthly demand is approximately normal, with mean 28 and standard deviation 8. Replenishment lead time for this part is about 4 weeks. The optimal EOQ for this part has been determined to be equal to 75. The owner of the store would like to maintain that there is no stock-out in 95% of the order cycles. (a) Find the resulting (Q, R) values. (b) Suppose that he wants to achieve a 90% fill rate. What fill rate did he actually achieve from the policy determined in part (a)? C. Problem Solving. 1. (20 points) A store uses a (QR) inventory system to control its stock levels.
