In group decision making (GDM), there may exist some problems that need to assign
alternatives to some predefined ordered categories, which are called ordinal classification …

This paper presents a consensus model for group decision making with interval
multiplicative and fuzzy preference relations based on two consensus criteria:(1) a …

This article presents a goal programming framework to solve group decision making
problems where decision-makers' judgments are provided as incomplete interval additive …

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 …

To generate solutions to multiple criteria group decision-making (MCGDM) problems that
are satisfactory to the decision makers, this paper proposes a new method. To examine …

In order to deal with a complex decision making problem, a group of experts are commonly
invited to express their opinions and reach a final decision. For the purpose of building …

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

Compatibility is a very efficient tool for measuring the consensus level in group decision
making (GDM) problems. The lack of acceptable compatibility can lead to unsatisfied or …

The individual consistency and the consensus degree are two basic measures to conduct
group decision making with reciprocal preference relations. The existing frameworks to …

Preference relations are a powerful tool to address decision-making problems. In some
situations, because of the complexity of decision-making problems and the inherent …
