The concept of hesitant set was introduced by Hu, which purpose is to unify hesitant fuzzy
sets, interval-valued hesitant fuzzy sets, shadowed sets etc. This paper discusses the …

In the fuzzy multicriteria decision-making approach, a committee of decision-makers is
usually involved in the assessment of the suitability of different alternatives based on the …

In this paper, we propose a novel group decision making (GDM) method in incomplete q-
rung orthopair fuzzy preference relations (q-ROFPRs) environments. We propose an …

Trapezoidal fuzzy numbers are efficient to represent the quantitative vagueness and
ambiguity of decision makers (DMs). Preference relations are powerful to express pairwise …

The q-rung orthopair fuzzy preference relations are useful tools to represent hesitant and
uncertain judgments of decision makers. In this paper, we propose a new group decision …

Neighborhood systems are used to approximate graphs as finite topological structures.
Throughout this article, we construct new types of eight neighborhoods for vertices of an …

This paper deals with group decision making (GDM) with hesitant fuzzy preference relations
(HFPRs) based on the acceptable multiplicative consistency and the consensus analysis …

Fuzzy linguistic preference relations (FLPRs) are an efficient way to express qualitative
judgments of decision makers (DMs). This paper proposes a new group decision making …

To represent decision makers' qualitative uncertainty and hesitation judgments, interval
linguistic hesitant fuzzy variables (ILHFVs) are efficient tools, which can be regarded as an …

Hesitant fuzzy linguistic preference relations (HFLPRs) can well denote the decision makers
(DMs)'hesitant qualitative comparison judgments. Considering that consistency and …
