Question

(OEM) is deciding on a new engine for its sports sedan. The three primary evaluation criteria are fuel efficiency, torque, and acceleration. Three engine concepts are being evaluated (A, B, and C). Through a pairwise comparison process, the following relationships were found between the criteria (Action 1-Find Weight, Step 1) Fuel efficiency Torque Acceleration Fuel efficiency 1 Torque Acceleration 1/4 1/3 Perform Step 2- Normalize Perform Step 3- Find the weight of each criteria by taking the mean of each row of the normalized matrix. Perform Step 4 Check for consistency Then the three engine concepts are pairwise compared against each criteria (Action 2-Scoring, Step I) and the comparisons are shown in the three tables below Fuel 1/2 1/2 Torque A B 1/5 1/3 Acceleration A 1/4 Perform Step 2 of Action 2 (Scoring), by normalizing then perform Step 3-finding the score of each concept by taking the mean of each row of the normalized matrix. Also, perform step 4 for consistency Finally, perform Action 3 and find the weighted scores then determine which is the best engine concept A, B, or C
