Wanda Lux must select a supplier for a plastic bottle and proprietary dispenser for its new hair shampoo. Three suppliers have placed bids; at Wanda's request, all bids are for a shipping quantity (Q) of 20,000 bottles with annual requirements (D) of 40,000 units. Wanda's factory operates 250 days a year. The following table shows each supplier's price, estimated annual freight costs, and current lead times; management has added estimates for holding costs and administrative oversight costs for each supplier.

Supplier	Freight Costs	Price/Unit (p)	Annual HoldingCost/Unit (H)	Lead Time(L) (days)	Annual Administrative Costs
Dover Plastics	$4,500	$5.10	$1.02	16	$4,000
Evan & Sons	$4,000	$5.15	$1.03	13	$3,000
Farley, Inc.	$3,000	$5.00	$1.00	19	$5,000

a. Which of the three suppliers will provide the lowest annual cost to Wanda Lux?

Using Farley is the lowest cost alternative, with annual total costs to Wanda Lux of $221040221040.

Beyond costs, however, Wanda has three other criteria considered important in the selection of a supplier. The following table shows all the criteria, their weights, and the scores for all of them except total costs, where a score of 1.0 indicates "poor" and 10 indicates "superior." Because all three suppliers have done business with Wanda Lux before, management will assign a score of "10" to the supplier with the lowest total annual cost, a score of "8.5" for the next lowest cost, and a score of "7.0" for the worst cost of the three.
