Intuitionistic fuzzy preference relations are powerful techniques used to express uncertain
preference information. However, simultaneously providing the exact priority and nonpriority …

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 …

In decision making with interval-valued intuitionistic fuzzy preference relations (IVIFPRs), the
consistency and its improvement are key issues. The aim of this paper is to investigate a …

This chapter develops a group decision-making (GDM) method that considers group
consensus and multiplicative consistency of interval-valued intuitionistic fuzzy (IVIF) …

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 …

Because of the complexity of interval-valued intuitionistic fuzzy set, there are few literatures
investigating the additive consistency of the interval-valued intuitionistic preference relation …

Interval-valued intuitionistic fuzzy preference relation (IVIFPR) is an important structure in
representing fuzzy information comprehensively. This paper focuses on the multiplicative …

Preference relations are an efficient technology to derive the priority vectors for the
alternatives in group decision-making. In this paper, an analysis of the existing research on …

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 discusses the theory and application of interval-valued intuitionistic fuzzy
preference relations (IVIFPRs). To do this, we first introduce an additive consistency concept …
