In large-scale group decision making (GDM), noncooperative behavior in the consensus
reaching process (CRP) is not unusual. For example, some individuals might form a small …

In multi-attribute group decision making, it is preferable that a set of experts reach a high
degree of consensus amongst their opinions, especially for large-scale group decision …

As a new improvement of fuzzy sets (FSs), spherical fuzzy sets (SFSs) can provide a wider
space for decision-makers (DMs) to express their preference information. Spherical fuzzy …

Consensus reaching processes play an increasingly important role in the resolution of group
decision making problems: a solution acceptable to all the experts participating in a problem …

In classical multiple attribute group decision making (MAGDM), decision makers evaluate
predefined alternatives based on predefined attributes. In other words, the set of alternatives …

A novel social network based group decision making (SN-GDM) model with experts' weights
not provided beforehand and with the following four tuple information: trust; distrust; …

In group decision making (GDM) with multiplicative preference relations (also known as
pairwise comparison matrices in the Analytical Hierarchy Process), to come to a meaningful …

In the multiple-attribute group decision-making (MAGDM), the decision objective is to obtain
a complete ranking of the alternatives from best to worst. In the real world, however …

This study investigates the group decision making under interval-valued intuitionistic fuzzy
environment in which the attributes and experts are in different priority level. We first propose …

In a multiple-criteria group decision-making process, it may be unrealistic to assume that all
experts are specialized in all aspects of the entire problem and can reach full agreement. To …
