The main purpose of this paper is to investigate the relationship between the entropy, the
similarity measure and the distance measure for hesitant fuzzy sets (HFSs) and interval …

In this paper, we propose a variety of distance measures for hesitant fuzzy sets, based on
which the corresponding similarity measures can be obtained. We investigate the …

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

In this paper, we take into account the hesitance degree of hesitant fuzzy sets, introduce the
concept of hesitance degree of hesitant fuzzy element which describes the decision maker's …

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 …

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 …

Dual hesitant fuzzy set (DHFS) is a very comprehensive set which includes fuzzy set,
intuition fuzzy set and hesitant fuzzy set as its special cases. Distance and similarity …

Distance and similarity measures act as the links from the expression of fuzzy information to
various application fields such as decision making, cluster analysis, medical diagnosis, and …

Distance measure is an important tool for distinguishing the difference between two objects.
To study the applications of hesitant fuzzy sets, several distance measures between hesitant …

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 …
