- Abstract:
-
The typical cut set is a bridge between fuzzy sets and clarity sets. The hesitant fuzzy set (HFS) theory, as an extension of the classical fuzzy set theory, has not been thoroughly studied till date; furthermore, there is less discussion regarding the relation between the HFS and classical type-I fuzzy set theory or other fuzzy set theories. This study analyzed the relations between the HFS and type-1 fuzzy set theory and between HFS and interval type-2 fuzzy set theory, proposed the concept of α-cut sets of HFS, and discussed their properties. Meanwhile, the decomposition (representation) theorems and the more general extension principles of HFS based on α-cut sets were deduced. The corresponding properties were studied. The results of the simulation prove the rationality of the α-cut set concept and provide a novel method for hesitant fuzzy multiple attribute decision-making and clustering analysis. All these conclusions deeply enrich the fundamental theory of HFS.
