Question 2) (35 points) A manufacturing company needs to select a new supplier. The company decided on four criteria, detected four candidate suppliers and evaluated the supplier performance for each criterion. The company uses AHP for the supplier selection process. a) (25 points) The management of the company provided the following pairwise comparisons. Four values indicated by letters A, B, C, and D are determined based on the last two digits of your student ID and the rules of AHP. Let the last two digits of your student ID number be XY and follow the steps: Step 1: Is Y odd? Yes: set A=Y No: set B=Y+1 Step 2: Is X odd? Yes: set C=X No: set D=X+1 Step 3: Compute remaining two letters accordingly. O For example, if your student ID number is 20150205072, then X=7 is odd and Y=2 is even. You should set B=Y+1=3 and C=X=7 and compute A and D values accordingly. (1,3,5,7,9 are odd and 0,2,4,6,8 are even.) Report the values of A, B, C and D and compute the weights up to three digits of precision. (for example if you compute a weight as 0.718212 then report it as 0.718) Price Quality Reliability A 3 1 Price (P) Quality (0) Reliability (R) R&D Capability (RD) 1 R&D Capability 1 1/7 1 1 1/3 B 1 1 1 D 7 b) (10 points) The company decided to use the following weights gone over the weights suggested by the top management and made some changes. The weights provided by the owner and the supplier scores for each criterion are given below. Compute the total score of each supplier using these weights and determine the best supplier.
