Question 38  (5 points)
Mission Computers, Inc. maintains CDRW Drive for sale throughout the year. The probability distribution of demand during lead time (DDLT) can be described as follows: ---------------------------- Demand(units) Probability 200 units 0.01 210 0.06 220 0.24 230 0.38 240 0.24 250 0.06 260 0.01 ---------------------------- Other information of the problem include: Annual Demand Rate (R) = 3600 units/yr; Value of the item (V) = $100/unit; Inventory Carrying Charge Rate (W) = 25%/yr; Order Setup Cost (A) = $200 per order. Stockout cost per unit (k)= $10/unit. In this case, applying the approach discussed in classes, the reorder point quantity which leads to the lowest total relevant costs (excess/safety stock holding costs, and expected stockout cost) should be
