Case: Sturdivant Sound Systems (1) The optimal order quantity is (see file P12-Sturdivant, sheet #1) is 183 units. (2). The reorder point is (20)(10) = 200 units, meaning they are actually ordering one cycle in advance when there are 17 units in hand. (3) Total annual cost under present system with an order level of 400 units is (see file P12-Sturdivant, sheet #2): Cost of equipment = (5,000 units)($60) = $300,000 Procurement costs = ($20 per order)(12.5 orders) = 250 Carrying costs = [(400/2) units]($6/unit) = 1,200 Total = $301,450 Total annual cost per optimal procurement policy is = (5,000)(60) + (5,000/183)(20) + (0.5)(183)(6) = $301,095.45. Cost savings = $301,450 - $301,095.45 = $354.55. (4) The typical costs associated with procurement of materials include costs of preparing requisitions, writing purchase orders, receiving merchandise, inspecting goods, storage, updating inventory records, and so on. These costs are usually fixed, regardless of the size of the order. While a large order may require more time, the increase in procurement costs is minimal. As lot size increases, the number of orders decreases (assuming a constant requirement level). Consequently, procurement costs will decrease with increases in lot sizes. | Sturdivant Sound Systems | 1. Compute the optimal order quantity. First, determine the cost under the present policy: Number of orders/year orders Average order size or 385 units Total cost = order cost + holding cost + purchase cost | Purchase cost: 5000 units 60/unit | = | 300,000 | | Order cost: $20/order 13 orders | = | 260 | | Carrying cost: | = | 1154 | | Total cost | | $301,414 | Next, develop an Economic Order Quantity, and determine the total costs: or 183 units where: D = period demand, S = setup or order cost, H = holding cost
