In this case, you do not need to write everything, but the results should be clearly stated and interpreted. If you made all the calculations manually, write everything and clearly state each step of the applications! a. According to the dominance principle, reduce the number of suppliers. b. Rank the final suppliers via conducting a median ranking approach. c. Suppose that the attribute weights are equal. Rank the alternatives via SAW, WP, and TOPSIS. Explain the findings and interpret them. d. Conduct sensitivity analysis for the ranking results of WP. For this purpose, suppose that Quality is two times more important than other alternatives that are equally weighted. Explain the findings and interpret them. 89 65 75 ABC company wants to reduce the Quality Performance Flexibility Speed number of suppliers it will work with in Supplier 1 35 35 40 45 the coming period by making a Supplier 2 14 X 10 17 40 performance evaluation of the candidate Supplier 3 57 60 45 60 suppliers.
