11. In an effort to improve customer service and reduce the cost of inventory, the Thanskavel Company
Question:
11. In an effort to improve customer service and reduce the cost of inventory, the Thanskavel Company invested in a number of lean manufacturing initiatives. One result of these investments was a reduction of the manufacturing lead time for the company’s specialty product, Eggsbar, from 6 weeks to 4 weeks. A study of Eggsbar disclosed that the demand averages 200 units per week, with a standard deviation of 22 units. The demand from one week to the next week was found to be independent.
a. What was the mean and standard deviation of the demand during manufacturing lead time for this product before and after the initiatives?
b. Thanskavel has a policy of holding extra finished goods inventory in the amount of 2.5 times the standard deviation of demand during manufacturing lead time. In the past, this amounted to $10,000 of extra inventory for this product. What reduction in extra inventory for this product resulted from the reduction of the manufacturing lead time?
