Applications of Spherical Fuzzy Sets in Ternary Semigroups

International Journal of Analysis and Applications, 2022
In this paper, we introduce the notions of spherical fuzzy ternary subsemigroups and spherical fuzzy ideals in ternary semigroups by using the concepts of ternary subsemigroups and ideals in ternary semigroups. We investigate their properties. Moreover, we study roughness of spherical fuzzy ideals in ternary semigroups.

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 ...

Prioritised fuzzy constraint satisfaction problems: axioms, instantiation and validation [PDF]

, 2003
This paper identifies a generic axiom framework for prioritised fuzzy constraint satisfaction problems (PFCSPs), and proposes methods to instantiate it (i.e., to construct specific schemes which obey the generic axiom framework).

Zero overshoot and fast transient response using a fuzzy logic controller [PDF]

, 2012
In some industrial process control systems it is desirable not to allow an overshoot beyond the setpoint or a threshold, this could be a safety constraint or the requirement of the system.

An Approach for the Assessment of Multi-National Companies Using a Multi-Attribute Decision Making Process Based on Interval Valued Spherical Fuzzy Maclaurin Symmetric Mean Operators

Axioms, 2022
Many fuzzy concepts have been researched and described with uncertain information. Collecting data under uncertain information is a difficult task, especially when there is a difference between the opinions of experts.

Notion of Complex Spherical Fuzzy Graph with Application

Journal of Function Spaces, 2022
A complex spherical fuzzy set (CSFS) is a generalization of a spherical fuzzy set (CFS). CSFS handles vagueness more explicitly, and its range is expanded from the real subset to the complex with unit disc.

Novel Complex T-Spherical Fuzzy 2-Tuple Linguistic Muirhead Mean Aggregation Operators and Their Application to Multi-Attribute Decision-Making

International Journal of Computational Intelligence Systems, 2020
Complex T-spherical fuzzy 2-tuple linguistic set (CTSF2-TLS), which is a combination of complex fuzzy set (CFS), T-spherical fuzzy set (TSFS), and 2-tulpe linguistic variable set (2-TLVS), is a proficient technique to express uncertain and awkward ...

Spherical Linear Diophantine Fuzzy Soft Rough Sets with Multi-Criteria Decision Making

Axioms, 2021
Modeling uncertainties with spherical linear Diophantine fuzzy sets (SLDFSs) is a robust approach towards engineering, information management, medicine, multi-criteria decision-making (MCDM) applications. The existing concepts of neutrosophic sets (NSs),

New aggregation functions for spherical fuzzy sets and the spherical fuzzy distance within the MULTIMOORA method with applications

Autonomous Intelligent Systems, 2022
AbstractThis article develops a novel approach for multi-objective optimization on the basis of ratio analysis plus the full multiplicative form (MULTIMOORA) using spherical fuzzy sets (SFSs) to obtain proper evaluations. SFSs surpass Pythagorean and intuitionistic fuzzy sets in modeling human cognition since the degree of hesitation is expressed ...
