ABC company wants to reduce the number of suppliers it will work with in Quality Performance Flexibility Speed Supplier / 35 35 45 the coming period by making a performance evaluation of the candidate Supplier 2 45 suppliers. For this reason, the board of Supplier 3 directors convened and evaluated the Supplier 4 48 45 45 40 suppliers over 100 points according to 4 Supplier 5 89 20 75 attributes. 100 is the best score in this Supplier 6 45 70 scale. Evaluation results are given in the Supplier 7 X*10 55 table. Note: If you used Excel. please do not forget to submit the Excel file. 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 cach 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. 2. A greengrocer observed that tomato sales are 12, 13, 14 or 15 kilos per day. The greengrocer did not calculate the probabilities because of not finding the past sales amounts reliable due to fluctuations in demand. She buys 1 kilo of tomatoes for 3.5 TL and sells them to her customers for 5.25 TL. Unsold tomatoes are sold to local restaurants for 2 TL at the end of the day. It is predicted that the cost of prestige loss caused by the customer coming to the grocery store and not finding tomatoes is 3 TL per kilo. Build the decision matrix and find the best decision using expected monetary value criterion (The probabilities needed should be determined by considering the principle of insufficient reason!).
