QUESTION 2: TOPSIS Stewart (1992) considered a site selection problem for electrical power plant among six European countries. The selection committee identified six attributes that determine the final selection: (1) X1 work force required (cost attribute) (2) X 2 power generated in MW (benefit attribute) (3) X3 construction cost in 10 6 US dollars (cost) (4) X4 annual maintenance cost in 10 6 US dollars (cost) (5) X5 number of villages to be evacuated (cost) (6) X6 safety level on an interval scale (benefit) Table 1 shows the rating of six countries in terms of the six attributes. The committee assumed equal weight among all attributes. Table 1 Candidate sites for power plant.
