Your company assembles five different models of a motor scooter that is sold in specialty stores in the United States. The company uses the same engine for all five models. You have been given the assignment of choosing a supplier for these engines for the coming year. Due to the size of your warehouse and other administrative restrictions, you must order the engines in lot sizes of 700 units. Because of the unique characteristics of the engine, special tooling is needed during the manufacturing process for which you agree to reimburse the supplier. Your assistant has obtained quotes from two reliable engine suppliers and you need to decide which to use. The following data have been collected: Requirements (annual forecast) Weight per engine Order processing cost Inventory carry cost 8,400 units 25 pounds $180 per order 20 percent of the average value of inventory per year Note: Assume that half of the lot size is in inventory, on average (700/2 - 350 units). Two qualified suppliers have submitted the following quotations: ORDER QUANTITY 1 to 1,499 unita/order 1.500 to 2,999 unite/order 3,000 - units/order Tooling conta Distance SUPPLIER 1 UNIT PRICE $ 672 662 652 624,80 130 miles SUPPLIER 2 UNIT PRICE 5 666 664 647 $22,100 100 miles Your assistant has obtained the following freight rates from your carrier Truckload (42,000 lb. each load) Less than-truckload: 50.80 per ton-mile 51.20 per ton ile Your assistant has obtained the following freight rates from your carrier: Truckload (42,000 lb. each load): Less-than-truckload: $0.80 per ton-mile $1.20 per ton-mile Note: Per ton-mile = 2,000 lb. per mile. a-1. Calculate the total cost for each supplier. (Round your answers to the nearest whole number.) Supplier 1 Supplier 2 Total cost a-2. Which supplier would you select? Supplier 1 Supplier 2 b-1. If you could move the lot size up to ship in truckload quantities, calculate the total cost for each supplier. (Do not round intermediate calculations. Round "Required lot size for truckload and final answers to the nearest whole number.) HINT: Use (full) truckload cost rates and the lowest (feasible) unit cost for all calculations. For example, if there are 8.3 orders per year, don't split the 8.3 orders into 8 full truckloads and 0.3 less-than-truckloads use the full truckload rate for all 8.3 orders. For annual purchase cost, don't use two different unit costs for the 8 complete orders and the 0.3 partial orders - use the lowest (feasible) unit cost for all 8.3 purchase orders based on the lot size needed for a full truckload.
