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 hesitant fuzzy set is a useful generalization of the fuzzy set that is designed for situations
in which it is difficult to determine the membership of an element to a set owing to ambiguity …

A bstract In this paper, we propose a new similarity measure between intuitionistic fuzzy
values based on the centroid points of transformed right-angled triangular fuzzy numbers …

The intuitionistic fuzzy set (IFS), as a generation of Zadeh's fuzzy set, can express and
process uncertainty much better. Similarity measures between IFSs are used to indicate the …

Three-way group decision-making is an important direction of study in the fields of three-way
decision-making and granular computing and has received much attention from scholars in …

The uncertainty and complexity of the decision‐making environment and the subjectivity of
the decision makers will lead to the inevitable errors of the decision‐making data. A poor …

Manufacturing robots are used for industrial purposes. Robots used for manufacturing
purpose have the power to create products from raw materials and are capable of operating …

A recent extension of intuitionistic fuzzy sets (IFSs) is the circular intuitionistic fuzzy set (C-
IFS), where the performance of each alternative is described by a circle with a fixed radius …

Atanassov's intuitionistic fuzzy set (IFS) is a generalization of a fuzzy set that can express
and process uncertainty much better. There are various averaging operators defined for …

To better deal with imprecise and uncertain information in decision making, the definition of
linguistic intuitionistic fuzzy sets (LIFSs) is introduced, which is characterized by a linguistic …
