Type-2 intuitionistic fuzzy sets possess many advantages over type-1 fuzzy sets because
their membership functions are themselves fuzzy, making it possible to model and minimize …

In a real world situation, whenever ambiguity exists in the modeling of intuitionistic fuzzy
numbers (IFNs), interval valued intuitionistic fuzzy numbers (IVIFNs) are often used in order …

According to the high importance of the university in the growth and development of the
country, the evaluation performance of educational and research groups in universities is …

Data envelopment analysis (DEA) is one of the best mathematical techniques to compute
the overall performance of units with some inputs and outputs. The original DEA methods …

Role of intuitionistic fuzzy sets (IFSs) in solving multiple attribute decision making (MADM)
problem has been established by many researchers. Depending upon the situation, we …

The aim of this paper is to investigate a novel approach to group decision making based on
DEA cross-efficiency with intuitionistic fuzzy preference relations, which can avoid …

In this study, a complete ranking method for interval-valued intuitionistic fuzzy numbers
(IVIFNs) is introduced by using a score function and three types of entropy functions. This …

This paper intends to propose a multi-attribute group decision making (MAGDM)
methodology based on MULTIMOORA under IFS theory for application in the assessment of …

A new entropy measure of interval‐valued intuitionistic fuzzy set (IVIFS) is proposed by
using cotangent function, which overcomes several limitations in the existing methods for …

In this paper, we mention and address the limitation of an existing conversion method of
intuitionistic fuzzy set (IFS) from fuzzy set (FS) and propose a novel conversion method for …
