Averaging aggregation functions for preferences expressed as Pythagorean membership grades and fuzzy orthopairs

open access: yes, 2014
Rather than denoting fuzzy membership with a single value, orthopairs such as Atanassov\u27s intuitionistic membership and non-membership pairs allow the incorporation of uncertainty, as well as positive and negative aspects when providing evaluations in

Theory of Systems, Systems Metaphysics and Neoplatonism [PDF]

open access: yes, 2015
Science has been developed from the rational-empirical methods, having as a consequence, the representation of existing phenomena without understanding the root causes.

A Novel Decision-Making Approach under Complex Pythagorean Fuzzy Environment

open access: yesMathematical and Computational Applications, 2019
A complex Pythagorean fuzzy set (CPFS) is an extension of a Pythagorean fuzzy set that is used to handle the vagueness with the degrees whose ranges are enlarged from real to complex subset with unit disc.

Decision-Making Approach under Pythagorean Fuzzy Yager Weighted Operators

open access: yesMathematics, 2020
In fuzzy set theory, t-norms and t-conorms are fundamental binary operators. Yager proposed respective parametric families of both t-norms and t-conorms. In this paper, we apply these operators for the analysis of Pythagorean fuzzy sets. For this purpose,

The interval‐valued hesitant Pythagorean fuzzy set and its applications with extended TOPSIS and Choquet integral‐based method

open access: yesInternational Journal of Intelligent Systems, 2019
The hesitant Pythagorean fuzzy set is frequently considered as a solution for decision making under uncertainty. Whereas the representation of uncertain information might be not sufficient in the hesitant Pythagorean fuzzy environment, thus the concept ...

On the Algebraic Attributes of (α, β)-Pythagorean Fuzzy Subrings and (α, β)-Pythagorean Fuzzy Ideals of Rings

open access: yesIEEE Access, 2022
$(\alpha,\beta)$ -Pythagorean fuzzy set is a very efficient way of dealing with uncertainty. In this article, we have introduced the notions of $(\alpha,\beta)$ - Pythagorean fuzzy subring and $(\alpha,\beta)$ - Pythagorean fuzzy ideal of a ring ...

A Potential Foundation for Emergent Space-Time [PDF]

open access: yes, 2014
We present a novel derivation of both the Minkowski metric and Lorentz transformations from the consistent quantification of a causally ordered set of events with respect to an embedded observer.

Pythagorean Fuzzy Muirhead Mean Operators and Their Application in Multiple-Criteria Group Decision-Making

open access: yesInformation, 2018
As a generalization of the intuitionistic fuzzy set (IFS), a Pythagorean fuzzy set has more flexibility than IFS in expressing uncertainty and fuzziness in the process of multiple criteria group decision-making (MCGDM). Meanwhile, the prominent advantage

Pythagorean Fuzzy Digraphs and Its Application in Healthcare Center

open access: yesJournal of Mathematics, 2021
The notion of fuzzy set is introduced to deal with uncertainty, whereas the conventional sets are used for certainty. The extensions of fuzzy set theory such as intuitionistic fuzzy set (IFS) and Pythagorean fuzzy sets (PyFS) were introduced to overcome ...
