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 …

Supporting the process of consensus building has become a major research field in group
decision making (GDM). The purpose of this paper is to present a consistency consensus …

The consistency measure is a vital basis for consensus models of group decision making
using preference relations, and includes two subproblems: individual consistency measure …

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 …

Preference transitivity characterized by ordinal consistency is a fundamental principle for
decision making models based on pairwise comparison matrices (PCMs). However, little …

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

Consistency and consensus play different, but essential roles when solving group decision
making problems using the analytical hierarchy process (AHP), in which multiplicative …

Analytic hierarchy process (AHP) is widely used in group decision making (GDM). There are
two traditional aggregation methods for the collective preference in AHP-GDM: aggregation …

With the rapid growth of Web 2.0 technology, a new paradigm has been developed that
allows many users to participate in decision-making processes within online social …

In many group decision-making situations, decision makers' preferences for alternatives are
expressed in preference relations (including fuzzy preference relations and multiplicative …
