Question 29 3 pts Annual demand for an item is 13,000 units with the cost per unit at $243. The holding rate is 10% and the order cost is $12.00 per order. The standard deviation of daily demand is 3 units. Assume 260 days in the year and a lead-time of 2 days. If a service level of 97% is desired during the reorder interval, what is the safety stock required? (Note: Due to rounding and your exact choice of...

A company manages its inventory for a specific item using the periodic review inventory model with 10 days between orders. It is currently time to place an order, and the company notes that there are 140 items on hand. The item to be replenished has a lead time of 6 days with a daily demand of 440 units. The standard deviation of demand during the uncertainty period has been calculated to be 65. If the company wants to have at...

Suppose now that the daily demand for the t-shirts is not deterministic. It is random with mean 2 and standard deviation 0.5. In addition, the lead time (the time it takes for an order to arrive at the store) is also random. Specifically, the mean lead time is six days and the standard deviation for the lead time is 1 day. The store uses an (s, Q) type inventory control policy. It sets the order quantity using the EOQ formula...
