Chapter 16 operational management hw
12. 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 1,000 each. 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 forcast) 12,000 units
Weight per engine 22 pounds
Order processing cost $125 per order
Inventory carry cost 20 percent of the average value of inventory per year
• Assume that half of lot size is in inventory on average (1,000/2= 500 units)
Two qualified suppliers have submitted the following quotations:
Order Quality Sup. 1 Unit $ Sup. 2 Unit $
1 to 1,499 units/order $510.00 $505.00
1,500 to 2,999 units/order 500.00 505.00
3,000+ units/order 490.00 488.00
Tooling costs $22,000 $20,000
Distance 125 miles 100 miles
Your assistant has obtained the following freight rates from your carrier:
Truckload (40,000 lbs. each load): $0.80 per ton-mile
Less-than-truckload: $1.20 per ton-mile
• Note: per ton-mile = 2,000 lbs. per mile.
a. Perform a total cost of ownership analysis and select a supplier.
b. Would it make economic sense to order in truckload quantities? Would your supplier
selection change if you ordered truckload quantities?
