Delving Into the Depths of the Properties and Behavior of Bipolar Pythagorean Neutrosophic Metric Spaces: A Theoretical Analysis

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This paper advances the theory of bipolar Pythagorean neutrosophic fuzzy (BPNF) sets by establishing their formalization within a topological and metric framework, while also demonstrating their role in decision‐making under uncertainty. The main contributions are as follows: (1) definition and characterization of BPNF topological spaces, providing a ...

Pythagorean Fuzzy Digraphs and Its Application in Healthcare Center

Journal 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 ...

q‐Fractional Hesitant Fuzzy Multicriteria Decision‐Making Approaches for Uncertain Power System Performance Evaluation

Energy Science &Engineering, Volume 13, Issue 11, Page 5311-5337, November 2025.
Evaluating power system performance based on a q‐fractional hesitant fuzzy model. ABSTRACT This study introduces novel q‐fractional hesitant fuzzy multicriteria decision‐making (MCDM) approaches aimed at optimizing power system performance under uncertain and imprecise conditions. We extend hesitant fuzzy set theory by formulating q‐fractional hesitant

A Hybrid AI and Fuzzy MCDM Approach for Retailer Evaluation: Leveraging Sentiment Analysis and Expert Insights

Applied AI Letters, Volume 6, Issue 3, October 2025.
This study proposes an AI‐enhanced decision‐making framework that integrates sentiment analysis of customer reviews with q‐rung orthopair fuzzy MCDM to evaluate retailer performance. By analyzing 8,000 reviews from major U.S. retailers, the model bridges unstructured feedback and structured evaluation, offering actionable insights into service ...

Decomposition of a Pythagorean fuzzy topological space and its application in determining topological relations between indeterminate spatial objects [PDF]

Journal of Fuzzy Extension and Applications
The fuzzy set generally identifies the topological relationship between two vague spatial objects. Indeterminacy can arise at any point in the modelling process, and the fuzzy model is unable to deal with this.

A new similarity measure for Pythagorean fuzzy sets [PDF]

Complex & Intelligent Systems, 2019
One of the methods of studying on two sets is to calculate the similarity of two sets. Triangular norms and conorms generalize the basic connectives between fuzzy sets, intuitionistic fuzzy sets, Pythagorean fuzzy sets. In this paper we used triangular conorms (S-norm).

A Fuzzy Decision‐Making Support Model for Traffic Safety Analysis

Expert Systems, Volume 42, Issue 9, September 2025.
ABSTRACT Our study delves into the crucial issue of road safety by examining the intricate dynamics of driver behaviour, often resulting in tragic accidents. The importance of comprehending these behaviours is acknowledged, leading us to propose an innovative decision‐making support model that integrates the analytic hierarchy process (AHP) with the ...

A new method for conversion between pythagorean fuzzy sets and intuitionistic fuzzy sets

Sigma Journal of Engineering and Natural Sciences – Sigma Mühendislik ve Fen Bilimleri Dergisi, 2022
Modeling with inconsistent fuzzy information is not possible for some problem types. For such cases, pythagorean fuzzy sets (PFSs) cannot be used in problem formulations and a conversion to another fuzzy set extension is needed. As a new conversion between PFSs and intuitionistic fuzzy sets (IFSs), the projective relation was proposed in the literature

Pathways to a Sustainable Blue Economy: Exploring Its Barriers in an Emerging Economy

Business Strategy and the Environment, Volume 34, Issue 5, Page 6095-6110, July 2025.
ABSTRACT A sustainable blue economy is primarily intended for responsible consumption of ocean resources, achieving economic growth, and strengthening the overall ecosystem. The roots of the blue economy are embedded in sustainable development, exploiting opportunities for economic welfare and growth, simultaneously focusing on conserving marine health.
