Abstract:

The multiple attributive group decision making problem that the rating of each alternative and the weight of each criterion are described by the fuzzy number is discussed by combining data fusion technology with triangular fuzzy number. For ranking fuzzy numbers, the conception of credibility measure is cited to calculate the relationship between two fuzzy numbers by fuzzy simulation, and the complementary judgment matrix is established to rank the order of alternatives. Finally, the results demonstrate that the proposed approach is feasible, effective and reasonable.
