With a view of generalizing intuitionistic fuzzy set (IFS), q-rung orthopair fuzzy set (q-ROFS)
was developed. The q-ROFS mitigates the limitation of IFS in terms of data representation …

This paper addresses the consistency and consensus of group decision making with
intuitionistic fuzzy preference relations (IFPRs). To check the consistency of IFPRs and the …

This paper presents a decision support system (DSS) for developing consensus in group
decision making. A fuzzy consensus index is proposed to evaluate group consensus in …

This chapter investigates the group decision making (GDM) problems with interval-valued
Atanassov intuitionistic fuzzy preference relations (IV-AIFPRs) and develops a novel method …

Pythagorean Fuzzy Preference Relations (PFPRs) have been considered in recent literature
more powerful and flexible than the popular intuitionistic fuzzy preference relation in dealing …

In this paper, a decision making method considering additive consistency and group
consensus is proposed to solve group decision making problems with linguistic intuitive …

Fuzzy set (FS) theory has long been introduced to handle inexact and imprecise data by
Zadeh (1965). The drawback of using the single membership value in FS theory is that it …
