A general assumption in group decision making scenarios is that of all individuals possess
accurate knowledge of the entire problem under study, including the abilities to make a …

In this paper, we propose a dynamical consensus scheme which makes use of an index of
comparability and of an index of concordance to regulate the information flow in the …

In group decision making (GDM) processes, prior to the selection of the best alternative (s), it
would be desirable that experts achieve a high degree of consensus or agreement between …

In this paper, some use of fuzzy preference orderings in group decision making is discussed.
First, fuzzy preference orderings are defined as fuzzy binary relations satisfying reciprocity …

The aim of this paper is to propose a procedure to estimate missing preference values when
dealing with incomplete fuzzy linguistic preference relations assessed using a two‐tuple …

The group decision-making framework with linguistic preference relations is studied. In this
context, we assume that there exist several experts who may have different background and …

Preference relations have been widely used in Group Decision Making (GDM) to represent
decision makers' preferences over alternatives. Recently, a new kind of preference relation …

The determination of solutions in group decision making is considered. The point of
departure is a collection of individual fuzzy preference relations. A solution is derived either …

With the development of intelligent decision-making, one kind of decision modes involves a
large number of decision-makers (DMs), which is called large scale group decision making …

In real-world decision problems, decision makers usually express their opinions with
different preference structures. In order to deal with the heterogeneous preference …
