1. Each supplier is rated on a 10-point scale (10 = highest)

for four different criteria: price, quality, delivery, and flexibility (to accommodate changes in quantity and timing). Because of the volatility of the business in which

Beagle operates, flexibility is given twice the weight of each of the other three criteria, which are equally weighted. The table below shows the scores for three potential suppliers for the four performance criteria. Based on the highest weighted score, which supplier should be selected?

Criteria	Supplier A	Supplier B       Supplier C
Price	8	6                            6
Quality _	9	7                            7
Delivery 1.	7	9                           6
Flexibility	5	8                          9

The Bennet Company purchases one of its essential raw materials from three suppliers. Bennet's current policy is to distribute purchases equally among the three. The owner's son, Benjamin Bennet, just graduated from a business college. He proposes that these suppliers be rated (high numbers mean a good performance) on six performance criteria weighted as shown in the table. A

total score hurdle of 0.60 is proposed to screen suppliers. Purchasing policy would be revised to order raw materi­als from suppliers with performance scores greater than the total score hurdle, in proportion to their performance rating scores.

			Rating	Supplier
		Supplier	Supplier
Performance Criterion	Weight	A
1. Price	0.2	0.6	0.5	0.9
2.  Quality	0.2	0.6	0.4	0.8
3.  Delivery	0.3	0.6	0.3	0.8
4.  Production facilities	0.1	0.5	0.9	0.6
5.    Environmental protection	0.1	0.7	0,8	0.6
6.  Financial position	0.1	0.9	1    0.9	0.7

 

a. Use a preference matrix to calculate the total weighted score for each supplier.

b. Which supplier(s) survived the total score hurdle? Un­der the younger Bennet's proposed policy, what pro­portion of orders would each supplier receive?

c. What advantages does the proposed policy have over the current policy?

2. Eight Flags operates several amusement parks in the Mid­west. The company stocks machine oil to service the ma­chinery for the many rides at the parks. Eight Flags needs 30,000 gallons of oil annually; the parks operate 50 weeks a year. Management is unsatisfied with the current supplier of oil and has obtained two bids from other sup­pliers.

Which supplier and which shipping quantity will provide the lowest costs for Eight Flags?
