Question

The campus store at a large Midwestern university sells writing tablets to students, faculty, and staff. They sell more tablets near exam time. During a typical 10-week quarter, the pattern of sales is 2,280, 1,120, 360, 3,340, 1,230, 860, 675, 1,350, 4,600, 1,210.The pads cost the store $1.20 each, and holding costs are based on a 30 percent annual interest rate. The cost of employee time, paperwork, and handling amounts to $30 per order.
Assume 50 weeks per year.
a. What is the optimal order policy during the 10-week quarter based on the Silver–Meal heuristic? Using this policy, what are the total holding and ordering costs incurred over the 10-week period?
b. The bookstore manager has decided that it would be more economical if the demand were the same each week. In order to even out the demand he limits weekly sales (to the annoyance of his clientele). Hence, assume that the total demand for the 10-week quarter is still the same, but the sales are constant from week to week. Determine the optimal order policy in this case and compare the total holding and ordering cost over the 10 weeks to the answer you obtained in part (a). (You may assume continuous time for the purposes of your calculations, so that the optimal lot size is the EOQ.)
c. Based on the results of parts (a) and (b), do you think that it is more economical in general to face a smooth or a spiky demand pattern?
