1. Cassorla's Clothes sells a large number of white dress shirts. The shirts, which bear the store label, are shipped from a manufacturer in New York City. Hy Cassorla, the proprietor, says, "I want to be sure that I never run out of dress shirts. I always try to keep at least a two months' supply in stock. When my inventory drops below that level, I order another two-month supply. I've been using that method for 20 years, and it works." The shirts cost $6 each and sell for $15 each. The cost of processing an order and receiving new goods amounts to $80, and it takes three weeks to receive a shipment. Monthly demand is approximately normally distributed with mean 120 and standard deviation 32. Assume a 20 percent annual interest rate for computing the holding cost.

A) What value of Q and R is Cassorla using to control the inventory of white dress shirts?

B) What should be the performance of a (s,S) model if Cassorla has 50 units during the review period?

C) What could be the (s,T) model policies by using an alpha (a) of 95% and a beta (B) of 90%?

Please answer ALL with clear numbers or computer like in the example above ^ I'll rate. If you only answer A) I'm going to downvote. Thanks. :)

EOQ = 2DS Reorder point = Average demand during lead time + Safety stock = L + safety stock Where: d= average demand per week (or day or months) L = constant lead time in weeks (or days or months) Safety stock = zodLT Where: z= number of standard deviations needed to achieve the cycle-service level. Odlt = standard deviation of demand during lead time. Reorder point = = dL + safety stock OLT= 70 OVC EOQ = 2DS Reorder point = Average demand during lead time + Safety stock = L + safety stock Where: d= average demand per week (or day or months) L = constant lead time in weeks (or days or months) Safety stock = zodLT Where: z= number of standard deviations needed to achieve the cycle-service level.
