Fuzzy Entropic Ordered Weighted Averaging Operator and Its Application in Group Decision Making

AbstractIn the paper, we develop a new method for multiple attribute group decision making for fuzzy numbers. The fuzzy entropic weighted averaging FEOWA operator is an extension of the entropic ordered weighted averaging operator, which unifies the fuzzy entropy and the ordered weighted averaging operator in the same formulation. Then, some of its main properties by utilizing some operational laws of fuzzy numbers are studied. We also present the generalized entropic ordered weighted averaging operator and the fuzzy generalized entropic ordered weighted averaging operator. Moreover, a method based on the FEOWA operator for decision making is presented. Finally, a numerical example illustrates the applicability and effectiveness of the proposed method.
