Nowadays, the increasing complexity of the social environment brings much difficulty in
group decision making. The more uncertainty exists in a decision-making problem, the more …

This book aims to justify the use of fuzzy logic as a logic and as an uncertainty theory in the
decision-making context. It also discusses the development of the TOPSIS method …

With the increasing complexity of decision-making environment and the development of
societal demands, large-scale group decision making (LSGDM) has become a hot topic in …

The uncertain group decision-making (UGDM) methodology has developed rapidly in recent
years, which is synchronous with the evolution of fuzzy set (FS) theory and linguistic term set …

A group consensus reaching process (CRP) based on dynamic expert reliability is proposed
in this paper. The method is designed to support uncertain multi-attribute group decision …

The intuitionistic fuzzy set has emerged as a powerful technique for presenting evaluations
under uncertainty. It simultaneously describes an object from above and below, that is, by …

Although intuitionistic fuzzy preference relations have become powerful techniques to
express the decision makers' preference information over alternatives or criteria in group …

In decision making with interval-valued intuitionistic fuzzy preference relations (IVIFPRs), the
consistency and its improvement are key issues. The aim of this paper is to investigate a …

Multiple-criteria or multiple-attribute group decision-making is a sub-field of operations
research that seek to find a common and representative solution given the preferences …

In GDM processes, after ensuring that all DHHFLPRs are of acceptable consistencies, we
cannot overlook another important step: the consensus reaching process, which is an …
