Interval linguistic term (ILT) is highly useful to express decision-makers'(DMs') uncertain
preferences in the decision-making process. This paper proposes a new group decision …

Large-scale group decision-making problems based on social network analysis and
minimum cost consensus models (MCCMs) have recently attracted considerable attention …

In real-life group decision-making (GDM) problems, the preferences given by decision-
makers (DMs) are often incomplete, because the complexity of decision-making problems …

In group decision-making (GDM) problems, the elicitation of preferences from decision
makers (DMs) and consensus reaching process are two critical issues to be resolved. Many …

There are more complex heterogeneous preference expressions and methods (HPEMs) in
heterogeneous multi-attribute group decision making (MAGDM) with several attribute sets …

Intuitionistic fuzzy variables are powerful tools to denote positive and negative information
simultaneously. Considering the situation where decision makers (DMs) may adopt different …

Interval linguistic fuzzy preference relations (ILFPRs) are powerful tools to denote the
decision makers' uncertain qualitative preferences. To avoid the inconsistent ranking results …

In this paper, we propose an optimization-based group decision making (GDM) method
using interval-valued intuitionistic fuzzy preference relations (IVIFPRs). First, the concept of …

Interval-valued intuitionistic preference relation (IV-IPR) is a new type of preference structure
used to describe uncertain evaluation information in decision making process. In this paper …

The complexity of multi-criteria decision problems requires the involvement of a group of
experts, who can contribute their knowledge, experience and opinions to the decision …
