A New Method for Fuzzy Group Decision-Making Based on Fuzzy Induced OWA Operators

In this paper, we present a new method for handling fuzzy group decision-making problems based on the proposed fuzzy induced ordered weighted averaging (FIOWA) operators. First, we construct fuzzy evaluating matrices for decision-makers with respect to the attributes of alternatives. Then, we calculate the weights of the attributes of the alternatives by using the proposed FIOWA operators. Then, we calculate the score of each alternative by using the proposed FIOWA operators and calculate the difference of the scores between alternatives. The smaller the difference of the scores between an alternative and the other alternatives, the better the choice of the alternative. The proposed method can handle fuzzy multiple attributes group decision-making problems in a more flexible manner than the method presented in due to the fact that the proposed method allows the order inducing variables and the argument variables in the OWA pairs to be represented by fuzzy sets.
