Child Development Influence Environmental Factors Determined Using Spherical Fuzzy Distance Measures
Mathematics, 2019 This paper aims to resolve the issue of the ranking of the fuzzy numbers in decision analysis, artificial intelligence, and optimization. In the literature, many ideas have been established for the ranking of the fuzzy numbers, and those ideas have some ...

Principals of Spherical Fuzzy Sets
, 2019 The 3D extensions of ordinary fuzzy sets such as intuitionistic fuzzy sets (IFS), Pythagorean fuzzy sets (PFS), and neutrosophic sets (NS) aim to describe experts’ judgments more informatively and explicitly. Introduction of generalized three dimensional spherical fuzzy sets (SFS) including some essential differences from the other fuzzy sets is ...

Extension of WASPAS with Spherical Fuzzy Sets [PDF]
Informatica, 2019 The 3D extensions of ordinary fuzzy sets such as intuitionistic fuzzy sets (IFS), Pythagorean fuzzy sets (PFS), and neutrosophic sets (NS) aim to describe experts' judgments more informatively and explicitly.In this paper, generalized three dimensional spherical fuzzy sets are presented with their arithmetic, aggregation, and defuzzification operations.

Topological Data Analysis with Spherical Fuzzy Soft AHP-TOPSIS for Environmental Mitigation System
Mathematics, 2022 The idea of spherical fuzzy soft set (SFSS) is a new hybrid model of a soft set (SS) and spherical fuzzy set (SFS). An SFSS is a new approach for information analysis and information fusion, and fuzzy modeling.

Intuitionistic fuzzy sets: Spherical representation and distances [PDF]
International Journal of Intelligent Systems, 2009 In Intuitionistic Fuzzy Set (IFS) theory more than 10 different geometrical interpretations are constructed. In the paper, two (the most popular) of them are discussed. A new -- spherical -- geometrical representation of the IFSs is described. The idea for it was introduced for the first time by \textit{I.

Heliyon, 2023 In many decision-making situations, we are not restricted to two kinds of aspects, such as membership degree or nonmembership degree, and sometimes we need to include the abstinence degree (AD). However, many fuzzy set theories fail to cover issues, such

Spherical fuzzy sets and spherical fuzzy TOPSIS method
Journal of Intelligent & Fuzzy Systems, 2018 All the extensions of ordinary fuzzy sets with three dimensional membership functions such as intuitionistic fuzzy sets (IFS), intuitionistic fuzzy sets of second type (IFS2), and neutrosophic fuzzy sets (NFS) aim at defining the judgments of decision makers/ experts with a more detailed description.

Using nonstationary fuzzy sets to improve the tractability of fuzzy association rules [PDF]
, 2013 Modern organisations now collect very large volumes of data about customers, suppliers and other factors which may impact upon their business. There is a clear need to be able to mine this data and present it to decision makers in a clear and coherent ...
