Typical hesitant fuzzy sets (THFSs), possessing a finite-set-valued fuzzy membership
degrees called typical hesitant fuzzy elements (THFEs), is a special kind of hesitant fuzzy …

Similarity measure is a very important topic in fuzzy set theory. Torra (2010) proposed the
notion of hesitant fuzzy set (HFS), which is a generalization of the notion of Zadeh'fuzzy set …

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 …

In fuzzy set (FS) theory, which is a generalization of classical set theory introduced by Zadeh
[1], distance, similarity and entropy measures have drawn the attention of many researchers …

Distance and similarity measures have recently been investigated in-depth within the
context of hesitant fuzzy sets. By analyzing the existing studies concerning distance …

Dual hesitant fuzzy set, first proposed by Zhu et al.(Dual hesitant fuzzy sets, J Appl Math, 1–
13, 2012) as an extension of hesitant fuzzy sets, which encompass fuzzy sets, intuitionistic …

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 …

Distance and similarity measures play a vital role to differentiate between two sets or
objects. Different distance and similarity measures had been proposed for hesitant fuzzy …

In this study, we propose new distance measures for dual hesitant fuzzy sets (DHFSs) in
terms of the mean, standard deviation of dual hesitant fuzzy elements (DHFEs), respectively …
