Hesitant fuzzy set (HFS) can express the hesitancy and uncertainty according to human's
cognitions and knowledge. The decision making with HFSs can be regarded as a cognitive …

Correlation coefficients characterize relationships of various fuzzy sets and thus facilitate
relevant applications. Regarding correlation coefficients of hesitant fuzzy sets (HFSs), a …

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

As an extension of the fuzzy set, the hesitant fuzzy set (HFS) is an effective tool for handling
uncertainty and vagueness in decision making problems. Considering that the correlation …

Hesitant fuzzy sets (HFSs) are becoming more and more popular in the fuzzy domain and
attract great attentions. As an important research orientation of HFSs, the correlation …

Hesitant fuzzy sets (HFSs) are considered as a powerful tool to deal with uncertain
information in the problems of group decision making (GDM). To measure the degree of …

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 …

Due to the importance of correlation coefficient in data analysis, researchers have shown
interest in the concept of correlation coefficient for the extensions of fuzzy sets, in particular …

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 theory provides an effective technique for researchers and engineers to
cope with vagueness and uncertainty. In recent years, to explore the correlation between …
