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

When a diverse group of experts share their knowledge to ascertain and solve a particular
multiple criteria decision-making (MCDM) problem, uncertainty arises from several sources …

The main aim of this paper is to present a consistency model for interval multiplicative
preference relation (IMPR). To measure the consistency level for IMPR, a referenced …

Purpose Consistency and consensus are two important research issues in group decision-
making (GDM). Considering some drawbacks associated with these two issues in existing …

In this paper, we introduce a new type of fuzzy preference structure, called Pythagorean
fuzzy preference relations (PFPRs), to describe uncertain evaluation information in group …

This paper investigates the likelihood comparison algorithm of triangular fuzzy numbers
(TFNs) and the additive consistency of triangular fuzzy preference relation (TFPR) for group …

Many group decision making (GDM) models enable experts to use only one preference
information representation form. It is natural to allow experts to express preferences in …

Intuitionistic multiplicative preference relation (IMPR) has been successfully and widely used
to model the decision makers' preferences elicited by pairwise comparisons. As the critical …

This research proposes a new method to solve group decision-making (GDM) problems with
intuitionistic fuzzy preference relations (IFPRs). First, a new definition of multiplicative …

This paper aims to develop a new group decision making (GDM) approach with intuitionistic
multiplicative preference relations (IMPRs) by considering the consistency and consensus …
