Question

The Bennet Company purchases one of its essential raw materi-
als 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 per-
formance) on six performance criteria weighted as shown in the
table. A total score hurdle of 0.60 is proposed to screen suppli-
ers. 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. 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?
