A New Methodology of Multicriteria Decision-Making in Supplier Selection Based on -Numbers

Figure 7

Methodology for the weight of the pairwise reciprocal judging matrix with -numbers in supplier selection. ① A method of converting -number to classic fuzzy number; ② an objective function according to the min-bias to the consistent weight; ③ the genetic algorithm is applied to solve the optimal fuzzy weight; ④ a centroid method is used to convert the fuzzy weight to crisp priority weight.
