Littlefield's supplier moved to a different city and now once an inventory replenishment order is placed, it takes exactly 7 days for the supplier to deliver this order as a lead time. Littlefield therefore cannot wait until its inventory to run out to place an order. A positive ReOrder Point (ROP) is set and as soon as the decreasing inventory level hits the ROP, an order with a size of EOQ is placed to the supplier. The ROP policy can be revised any time before the next order is placed. The ROP problem can also be considered a Newsvendor problem to determine an inventory quantity facing a 7-day random demand, Littlefield purchases the kits from the supplier at a price of $600 each and the money is immediately deducted from an interest-bearing bank account with an annual interest rate of 6% when an inventory replenishment order is place with the supplier. Assume that in each inventory ordering cycle, a $11 per unit overstocking cost occurs for the leftovers. On the other hand, if Littlefield runs out of inventory, a $1100 per unit understocking cost occurs since Littlefield agrees to pay a $1100 rebate for each job that starts late. What is the Critical Ratio in the Newsvendor model to help Littlefield decide how many units to hold to cover a 7-day demand during the supplier lead time? (The Critical Ratio is, in essence, the optimal service level to run.) (Your simulation case may vary.)

On the other hand, if Littlefield runs out of inventory, a $1100 per unit understocking cost occurs since Littlefield agrees to pay a $1100 rebate for each job that starts late. It is estimated that Littlefield's weekly demand is normally distributed with a mean of 20 jobs and standard deviation of 3 jobs.
