The paper aims at introducing novel distance measures for the intuitionistic fuzzy set (IFS) to
discuss the decision-making problems. The current work exploits four different notions of …

Pythagorean fuzzy set (PFS), originally proposed by Yager, is more capable than
intuitionistic fuzzy set (IFS) to handle vagueness in the real world. The main purpose of this …

The q‐rung orthopair fuzzy set (q‐ROFS), originally developed by Yager, is more capable
than that of Pythagorean fuzzy set to deal uncertainty in real life. The main goal of this paper …

Soft set theory, initially introduced through the seminal article “Soft set theory—First results”
in 1999, has gained considerable attention in the field of mathematical modeling and …

Decision‐making under uncertainty is consistently an essential fear and the most
challenging circle of exploration. To manage the uncertainty, the intuitionistic fuzzy set (IFS) …

Pythagorean fuzzy set theory is one of the significant tools to deal with real-life problems
which are prone to imprecision, partial truth or uncertainty. A Pythagorean fuzzy set reports …

Unlike an ordinary fuzzy set, the concept of intuitionistic fuzzy set (IFS), characterized both
by a membership degree and by a non-membership degree, is a more flexible way to …

The power average operator can relieve the some influences of unreasonable data given by
biased decision makers, and Heronian mean operator can consider the interrelationship of …

In this paper we propose an entropy measure for interval-valued intuitionistic fuzzy sets,
which generalizes three entropy measures defined independently by Szmidt, Wang and …

Intuitionistic fuzzy set (IFS) is a representative model of fuzzy theory, and it is widely used to
deal with fuzzy and uncertain problems in many practical applications. In IFS theory, the …
