1. The NusrET Company purchases one of its essential raw materials from three suppliers. NusrET's current policy is to distribute purchases equally among the three. An engineer proposes that these suppliers be rated 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 B C Price 0.2 0.6 RN 0.9 Quality 0.2 RN 0.4 0.8 Delivery 0.3 0.6 0.3 RN Production Facilities 0.1 0.5 RN 0.6 Environmental Protection 0.1 RN 0.8 0.6 Financial Position 0.1 0.9 0.9 RN RN: Create random number between 0.3 and 0.9 (Different). (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 engineer's proposed policy, what proportion of orders would each supplier receive
