Hesitant fuzzy set (HFS) is now attracting more and more scholars' attention due to its
efficiency in representing comprehensively uncertain and vague information. Considering …

As an extension of the fuzzy set, the hesitant fuzzy set (HFS) is an effective tool for handling
uncertainty and vagueness in decision making problems. Considering that the correlation …

Hesitant fuzzy set (HFS) is a powerful decision tool to express uncertain information more
flexibly and comprehensively. The aim of this paper is to propose more reasonable …

In this paper, several new correlation coefficients of hesitant fuzzy sets are defined, not
taking into account the length of hesitant fuzzy elements and the arrangement of their …

Abstract Hesitant Fuzzy Sets (HFSs) is an important tool to deal with uncertain and vague
information. There have been lots of fuzzy measures for it from different views. However …

Hesitant fuzzy sets (HFSs) are beneficial tools for expressing the hesitancy of decision
makers (DMs) to access alternatives in daily life, thereby enabling the membership of an …

Distance and similarity measures are fundamentally important in a variety of scientific fields
such as clustering analysis, pattern recognition and decision making, etc. In this paper, by …

In this study, we extend the hesitant fuzzy set (HFS) to its higher order type and refer to it as
the higher order hesitant fuzzy set (HOHFS). HOHFS is the actual extension of HFS that …

The objective of the authors is to establish an innovative concept of the complex hesitant
fuzzy set (CHFS), which is the combination of the hesitant fuzzy set and the complex fuzzy …

The distance measures of hesitant fuzzy elements (HFEs) h 1 (x) and h 2 (x) introduced in
the literature only cover the divergence of the values, but fail to consider the difference …
