The group-ranking problem is ubiquitous in the real life, which is a group decision-making
(GDM) problem and cannot be completed independently by individuals. However, different …

This study presents a novel minimum deviation ordinal consensus model (MDOCM) for
group decision making with heterogeneous preference structures (utility values, preference …

This paper aims to propose an innovative approach to group decision making (GDM) with
interval-valued intuitionistic fuzzy (IVIF) preference relations (IVIFPRs). First, an IVIFPR is …

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

Preference-approval structure is a typical preference structure that can not only reflect
decision makers' preference orderings for alternatives but also distinguish the satisfied …

This paper aims to offer a new group decision-making (GDM) method based on interval-
valued intuitionistic fuzzy preference relations (IVIFPRs). To furnish this goal, a new additive …

The priority weight vectors of an intuitionistic fuzzy preference relation (IFPR) with linear
uncertainty distribution characteristics in group decision making (GDM) are determined in …

Deriving priority vectors for preference relations in group decision-making (GDM) is an
interesting research topic. In this paper, this issue is examined for GDM with fuzzy …

In this paper, we introduce a new kind of preference relation called the interval-valued
intuitionistic multiplicative preference relation (IVIMPR). Then, we develop two types of …

Although fuzzy preference relations (FPRs) are among the most commonly used preference
models in group decision making (GDM), they are not free from drawbacks. First of all …
