Incomplete preferences have become increasingly common in light of the redundancy of
information and time-related pressures. Incomplete fuzzy preference relations (IFPRs) have …

Two processes are necessary to solve group decision making problems: A consensus
process and a selection process. The consensus reaching process is necessary to obtain a …

Consensus is defined as a cooperative process in which a group of decision makers

A group selection of one alternative from a set of feasible ones should be based on the
preferences of individuals in the group. Decision making procedures are usually based on …

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 …

This paper focuses on heterogeneous group decision making (GDM) in the setting of
incomplete preference relations, including incomplete fuzzy preference relations, incomplete …

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 …

The consistency measure is a vital basis for group decision making (GDM) based on fuzzy
preference relations, and includes two subproblems: individual consistency and consensus …

This paper reviews and analyzes several consistency concepts for interval fuzzy preference
relations (IFPRs). On the basis of the comparisons, one can find that Krejčí's additive and …
