A random set and prototype theory interpretation of intuitionistic fuzzy sets [PDF]

, 2010
An interpretation of intuitionistic fuzzy sets is proposed based on random set theory and prototype theory. The extension of fuzzy labels are modelled by lower and upper random set neighbourhoods, identifying those element of the universe within an ...

Spherical Linear Diophantine Fuzzy Graphs: Unleashing the Power of Fuzzy Logic for Uncertainty Modeling and Real-World Applications

Axioms
The theory of spherical linear Diophantine fuzzy sets (SLDFS) boasts several advantages over existing fuzzy set (FS) theories such as Picture fuzzy sets (PFS), spherical fuzzy sets (SFS), and T-spherical fuzzy sets (T-SFS).

A new approach to r,s,t-spherical fuzzy soft sets with applications to multi-criteria decision-making [PDF]

Big Data and Computing Visions
As an extension of T-Spherical Fuzzy Soft Sets (T-SFSS), the notion of r,s,t-Spherical Fuzzy Soft Sets (rst-SFSS) is presented in this study. Incorporating the degrees of membership, neutral membership, and non-membership into a more adaptable structure,

Dynamic Chaotic Multi-Attribute Group Decision Making under Weighted T-Spherical Fuzzy Soft Rough Sets

Symmetry, 2023
In this article, the parameter of the decision maker’s familiarity with the attributes of the alternatives is introduced for the first time in dynamic multi-attribute group decision making to avoid the disadvantages arising from the inappropriate grouping of decision makers.

Correlation of fuzzy sets

, 2011
When we deal with crisp data, it is very common to find the correlation between variables. Here, we propose a method to calculate the correlation coefficient for fuzzy data, but rather than defining the correlation on the intuitionistic fuzzy sets like ...

Generalized and Customizable Sets in R [PDF]

, 2009
We present data structures and algorithms for sets and some generalizations thereof (fuzzy sets, multisets, and fuzzy multisets) available for R through the sets package. Fuzzy (multi-)sets are based on dynamically bound fuzzy logic families.

Hamacher Maclaurin symmetric mean aggregation operators and WASPAS method for multiple criteria group decision making under T - spherical fuzzy environment

Results in Control and Optimization
T-spherical fuzzy sets can accurately represent fuzzy information and effectively simulate real-world decision making scenarios by adjusting the parameter t.
