A new group decision making method based on likelihood-based comparison relations of hesitant fuzzy linguistic term sets

In this paper, we present a new group decision making method based on likelihood-based comparison relations of hesitant fuzzy linguistic term sets. The likelihood-based comparison relation of hesitant fuzzy linguistic term sets is used to compare two hesitant fuzzy linguistic term sets. The fuzzy optimistic target, the fuzzy neutral target and the fuzzy pessimistic target are used to reflect experts´ attitudes. The proposed method is more flexible than the existing method due to the fact that it considers experts´ attitudes for group decision making. It provides us with a useful way for group decision making in a fuzzy environment.
