Present Worth Analysis Using Pythagorean Fuzzy Sets
2017One of the investment decision making techniques is present worth analysis (PWA) and it is almost the most frequently used one. Uncertain cash flows, uncertain life, and uncertain time value of money cause the usage of a fuzzy PWA. In this paper, we develop a Pythagorean fuzzy present worth analysis method to handle the fuzzy parameters of investments.

Grey Pythagorean Fuzzy Sets for Decision-Making
International Journal of Information Technology & Decision MakingAs a generalized extension of fuzzy sets, Pythagorean fuzzy sets (PFSs) provide a sophisticated framework for modeling subjective uncertainty inherent in human cognition. Real-world decision-making systems frequently exhibit concurrent uncertainties characterized by incompleteness and fuzziness.

Possibility Pythagorean fuzzy soft set and its application
Journal of Intelligent & Fuzzy Systems, 2019In this paper, we propose the theory of possibility Pythagorean fuzzy soft set and define some related the operations concerning this notion including the complement, union, intersection, AND and OR. Then a similarity measure is introduced to compare two possibility Pythagorean fuzzy soft sets for dealing with decision problems.

Some New Operations on Pythagorean Fuzzy Sets
Uncertainty Discourse and ApplicationsThe concept of Pythagorean fuzzy sets (PFSs) was initially developed by Yager in 2013, which provides a novel way to model uncertainty and vagueness with high precision and accuracy compared to Pythagorean fuzzy sets (PFSs).The concept was concretely designed to represent uncertainty and vagueness in mathematical way and to furnish a formalized tool ...

Properties and Applications of Pythagorean Fuzzy Sets
2015We introduce the concept of Pythagorean fuzzy subsets and discuss its relationship with intuitionistic fuzzy subsets. We focus on the negation and its relationship to the Pythagorean theorem. We describe some of the basic set operations on Pythagorean fuzzy subsets.

Distance and similarity measures for Pythagorean fuzzy sets
Granular Computing, 2018The concept of Pythagorean fuzzy sets is very much applicable in decision science because of its unique nature of indeterminacy. The main feature of Pythagorean fuzzy sets is that it is characterized by three parameters, namely, membership degree, non-membership degree, and indeterminate degree, in such a way that the sum of the square of each of the ...
