Group decision making (GDM) has been widely focused on for coping with the complexity of
a practical decision making problem. This paper proposes a relative projection-driven GDM …

Group decision making (GDM) is a wisdom extracting process where a group of decision
makers (DMs) could reach a consensus on the optimal solution to the choice problem with a …

Reciprocal fuzzy preference relation (FPR) is a hot topic in the research field of group
decision making (GDM). Within the framework of GDM, a two-stage consensus reaching …

Consensus reaching models are widely used to derive a representative solution in group
decision‐making problems. Current models present limitations regarding the achievement of …

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

The existing methods for solving the group decision making (GDM) problems with
preference relations generally include four steps:(1) estimation of missing preferences,(2) …

Consistency and consensus study for group decision making (GDM) with fuzzy preference
relations (FPRs) are necessary, which have a decisive impact on the quality of decision …

This paper presents a new method to coping with group decision making with incomplete
fuzzy preference information. To do this, it first defines an additively consistent index of fuzzy …

Supporting the process of consensus building has become a major research field in group
decision making (GDM). The purpose of this paper is to present a consistency consensus …

The purpose of this paper is to study a group decision-making (GDM) problem in which the
preference information about the alternative provided by the decision makers can be of a …
