Interval-valued hesitant fuzzy sets (IVHFSs), as an extension of hesitant fuzzy sets, can
account for the membership degrees of an element to a given set having a few different …

Due to convenience and powerfulness in dealing with vagueness and uncertainty of real
situation, hesitant fuzzy set has received more and more attention and has been a hot …

The hesitant fuzzy linguistic term set (HFLTS) is a new and flexible tool in representing
hesitant qualitative information in decision making. Correlation measures and correlation …

Hesitant fuzzy sets (HFSs), interval-valued hesitant fuzzy sets (IVHFSs) and typical dual
hesitant fuzzy sets (T-DHFSs) are new extensions of classical fuzzy sets (FSs) that have …

Complex dual hesitant fuzzy set (CDHFS) is an assortment of complex fuzzy set (CFS) and
dual hesitant fuzzy set (DHFS). In this manuscript, the notion of the CDHFS is explored and …

As a generalized fuzzy number, the hesitant fuzzy element (HFE) has received increasing
attention. However, it is noted that the occurring probabilities of the elements in the HFE are …

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 …

Compared to hesitant fuzzy sets and intuitionistic fuzzy sets, dual hesitant fuzzy sets can
model problems in the real world more comprehensively. Dual hesitant fuzzy sets explicitly …

The purpose of this study is to reduce the uncertainty in the calculation process on hesitant
fuzzy sets (HFSs). The innovation of this study is to unify the cardinal numbers of hesitant …

The hesitant fuzzy linguistic term set (HFLTS) turns out to be useful in representing people's
hesitant qualitative information. The aim of this paper is to investigate new correlation …
