In the process of group decision making (GDM), preference relations (eg fuzzy preference
relation and multiplicative preference relation) are very popular tools to express decision …

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

The hesitant fuzzy preference relation (HFPR) was recently introduced by Zhu and Xu to
allow the decision makers (DMs) to offer several possible preference values over two …

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 …

As we may have a set of possible values when comparing alternatives (or criteria), the
hesitant fuzzy preference relation becomes a suitable and powerful technique to deal with …

In this paper, we explore the ranking methods with hesitant fuzzy preference relations
(HFPRs) in the group decision making environments. As basic elements of hesitant fuzzy …

In order to simulate the hesitancy and uncertainty associated with impression or vagueness,
a decision maker may give her/his judgments by means of hesitant fuzzy preference …

We introduce a new type of fuzzy preference structure, called interval-valued hesitant
preference relations, to describe uncertain evaluation information in group decision making …

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 …

Hesitancy is the most common problem in decision making, for which hesitant fuzzy set can
be considered as a suitable means allowing several possible degrees for an element to a …
