Exhibit 12-3The North Slope Clothing Store Chain Sells Approximately 26,000

Exhibit 12-3The North Slope clothing store chain sells approximately 26,000 units of its most popular cotton sweater each year. North Slope buys these sweaters from a manufacturer located in Canada. The fixed cost of placing an order for this particular product is $200. North Slope pays $10 for each cotton sweater. The company's cost of capital is 11%, and the cost of storing a sweater for one year is $1.10. While North Slope prefers not to backlog customer demand, management of the company believes that it can afford to run out of sweaters on an occasional basis. The company estimates that the shortage cost per sweater per year is about $20.
-Refer to Exhibit 12-3. Suppose again that the annual demand for the sweaters is not known with certainty, but rather is estimated to be normally distributed with mean 26,000 and standard deviation 2,000. However, this time, formulate a Solver model to find the optimal (R,Q) policy to ensure that at least 99% of customer demands are met with existing inventory. What is the policy, and what is the total annual cost in that case?
