Hesitant fuzzy set is a powerful and effective tool to express uncertain information in multi-
attribute decision-making (MADM) process, as it permits the membership degree of an …

A dual hesitant fuzzy set (DHFS) consists of two parts, that is, the membership hesitancy
function and the nonmembership hesitancy function, supporting a more exemplary and …

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 …

Hesitant fuzzy set (HFS), which allows the membership degree of an element to a set
represented by several possible values, is considered as a powerful tool to express …

As a new preference structure, the hesitant fuzzy linguistic preference relation (HFLPR) was
recently introduced by Rodríguez, Martínez, and Herrera to efficiently address situations in …

The concept of hesitant fuzzy preference relation (HFPR) has been recently introduced to
allow the decision makers (DMs) to provide several possible preference values over two …

Hesitant fuzzy linguistic preference relation (HFLPR) is a new preference structure that the

In this paper, we develop a novel multiattribute decision making (MADM) approach based
on Fermatean hesitant fuzzy sets (FHFSs) and the modified VIKOR method. Firstly, we …

Pythagorean fuzzy sets (PFSs), hesitant fuzzy sets (HFSs) and intuitionistic hesitant fuzzy
sets (IHFSs) have attracted more and more scholars' attention due to their powerfulness in …
