The hesitant fuzzy element (HFE), as an extension of fuzzy numbers, has received much
attention and the occurrence probabilities of each membership in the HFEs are assumed to …

As a powerful extension to fuzzy set, hesitant fuzzy set (HFS) attracted many scholars in the
recent times. The HFS had the ability to accept multiple membership values for a specific …

Due to the characteristics of hesitant fuzzy sets (HFSs), one hesitant fuzzy element (HFE),
which is the basic component of HFSs, can express the evaluation values of multiple …

Hesitant fuzzy sets were introduced by Torra to efficiently address situations in which the
membership degree of an element in a set is expressed by several different values …

In this paper, we initially re-define the existing definition of extended hesitant fuzzy set
(EHFS) using the Cartesian product of hesitant fuzzy sets (HFSs). This is while, the EHFS …

In the era of uncertain information everywhere, the Probabilistic Hesitant Fuzzy sets (PHFs),
utilizing the possible numbers and its possible membership degrees to descript decision …

The hesitant fuzzy set (HFS) has received wide attention because it can neatly describe the
fuzziness and hesitancy of decision information with several possible values. Hence, this …

With regard to element uncertainty in a hesitant fuzzy element (HFE), the probabilistic
hesitant fuzzy element (PHFE) was developed. It has been noted that the occurrence …

A hesitant fuzzy set is a flexible generalization of a fuzzy set that permits agents to furnish
multiple views and the occurrence probability of each element is either the same or …

Abstract Background/Introduction Due to the complexity and uncertainty of socioeconomic
environments and cognitive diversity of group members, the cognitive information over …
