| Abstract: | ABSTRACT We present a new information fusion algorithm for fusing fuzzy opinions in a heterogeneous group decision-making environment. The proposed information fusion algorithm has the following advantages: (1) It uses linguistic quantifiers based on the FN-IOWA operator to flexibly determine the weight w i of the opinion of each expert E i for aggregating the experts' fuzzy opinions. (2) The experts' opinions do not necessarily need to have a common intersection. (3) It does not need to use the Delphi method to adjust fuzzy numbers given by experts. |
