The aim of this paper is to investigate information aggregation methods under Pythagorean
trapezoidal fuzzy environment. Pythagorean fuzzy set, an extension of the intuitionistic fuzzy …

The Pythagorean fuzzy number is a new tool for uncertainty and vagueness. It is a
generalization of fuzzy numbers and intuitionistic fuzzy numbers. In this paper, we define …

Pythagorean fuzzy sets accommodate more uncertainties than the intuitionistic fuzzy sets
and hence it is one of the most important concepts to describe the fuzzy information in the …

As an extension of fuzzy set, a Pythagorean fuzzy set has recently been developed to model
imprecise and ambiguous information in practical group decision‐making problems. The …

Pythagorean fuzzy set is a useful tool to deal with the fuzziness and vagueness. Many
aggregation operators have been proposed by many researchers based on Pythagorean …

Pythagorean fuzzy sets (PFSs) accommodate more uncertainties than Lx the intuitionistic
fuzzy sets and hence its applications are more extensive. Under the PFS, the objective of …

In this paper, we investigate the multiple attribute group decision making (MAGDM)
problems with interval‐valued Pythagorean fuzzy sets (IVPFSs). First, the concept …

The aim of this paper is to investigate information aggregation methods under Pythagorean
trapezoidal fuzzy environment. Some Einstein operational laws on Pythagorean trapezoidal …

Pythagorean fuzzy number is a new tool for uncertainty and vagueness. It is a generalization
of fuzzy numbers and intuitionistic fuzzy numbers. This paper deal with induced interval …

Methods for aggregating intuitionistic trapezoidal fuzzy information are investigated. Some
operational laws of intuitionistic trapezoidal fuzzy numbers are introduced. Based on these …
