how are you calculating the SL value of 1.64?
- Thomas' Bike Shop stocks a high volume item that has a normally distributed demand during the reorder period. The average daily demand is 70 units, the lead time is 4 days, and the standard deviation of demand during the reorder period is 15. How much safety stock provides a 95% service level to Thomas? What should the reorder point be?Annual demand for a product is 13,000 units; weekly demand is 250 units with a standard deviation of 40 units. The cost of placing an order is $100, and the time from ordering to receipt is four weeks. The annual inventory carrying cost is $0.65 per unit. To provide a 98 percent service probability, what must the reorder point be? Note: Use Excel's NORM.S.INV() function to find the z value. Round z value to 2 decimal places and final answer to the nearest whole number. Suppose the production manager is told to reduce the safety stock of this item by 100 units. If this is done, what will the new service probability be? Note: Use Excel's NORM.S.DIST() function to find the correct probability for your computed z value. Round z value to 2 decimal places and final answer to the nearest whole percent.Walrus Company has the following information available concerning one of its inventory items: Cost of placing an order $30.00 Unit carrying cost per year $3.00 Annual unit demand 6,625 Safety stock 125 Average daily demand 25 Normal lead time in days 10 If there is a delay in shipping the item, approximately how many days can be covered by the safety stock? a.5 days b.110 days c.26 days d.31 days
