The Intuitionistic Fuzzy Normed Space of Coefficients

Abstract and Applied Analysis, 2012
Intuitionistic fuzzy normed space is defined using concepts of t-norm and t-conorm. The concepts of fuzzy completeness, fuzzy minimality, fuzzy biorthogonality, fuzzy basicity, and fuzzy space of coefficients are introduced. Strong completeness of fuzzy

Archimedean-Compensatory Fuzzy Logic Systems [PDF]

International Journal of Computational Intelligence Systems, 2015
The paper aims to define a new kind of logic, referred to as Archimedean-Compensatory Logic, which is constructed from the unification of two different fuzzy logic systems, namely a continuous Archimedean fuzzy logic and a compensatory fuzzy logic.

Edelstein Fixed Point Theorem in Neutrosophic Metric Spaces With an Application to an SIR‐Type Epidemic Model

International Journal of Differential Equations, Volume 2026, Issue 1, 2026.
In this paper, utilizing the concept of neutrosophic metric spaces proposed by Kirisci and Simsek, we establish a fixed point theorem of Edelstein type within this framework. A numerical example is provided to illustrate the validity of the main result. Furthermore, we present an application to a general SIR‐type epidemic model.

Multi-Attribute Decision-Making Method Based on Interval-Valued $q$ -Rung Orthopair Fuzzy Archimedean Muirhead Mean Operators

IEEE Access, 2019
Interval-valued q-rung orthopair fuzzy sets (IVq-ROFSs), as a generalization of q-rung orthopair fuzzy sets (q-ROFSs), are the powerful tool for mastering the fuzziness of information.

Development of Linear Diophantine Fuzzy Z‐Number Aczel–Alsina Aggregation Operators and Their Use in a Hybrid MCDM Framework for Medical Diagnosis

International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
A linear Diophantine Z‐number Aczel–Alsina t‐norm operator is implemented for solving a linear Diophantine Z‐number problem, along with explaining its reliability, along with the solution derived. Some basic mathematical characteristics of the introduced operator, such as monotonicity, boundedness, and homogeneity, are rigorously deduced mathematically

Andness Directedness for t-Norms and t-Conorms

Mathematics, 2022
Tools for decision making need to be simple to use. In previous papers, we advocated that decision engineering needs to provide these tools, as well as a list of necessary properties that aggregation functions need to satisfy. When we model decisions using aggregation functions, andness-directedness is one of them.

Generalizing Leximin to t-norms and t-conorms [PDF]

IEEE Annual Meeting of the Fuzzy Information, 2004. Processing NAFIPS '04., 2004
The Leximin procedure, introduced by Dubois and Prade in 1996, provides a methodology for adjudicating ties in aggregated values when using the min t-norm. Here, with the introduction of the LexiT procedure, we generalize these ideas to provide a tool for adjudicating des when aggregating data using any t-norm.

An Integrated T‐Spherical Fuzzy 2‐Tuple Linguistic WASPAS Framework With Hamy Mean Aggregation for Wildlife Conservation Planning

Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.
Due to the inherent uncertainty in selecting a best alternative, T‐spherical fuzzy 2‐tuple linguistic (T‐SF2TL) sets will be an advantageous method for decision makers (DMs) to assist their evaluations within T‐SF2TL framework. The objective of this study is to establish weighted Hamy mean (WHM) and weighted dual Hamy mean (WDHM) operators within the ...

Topological Aspects of Set-Valued Mappings Defned on Neutrosophic Normed Spaces [PDF]

Neutrosophic Sets and Systems
Samarandache [43] introduced neutrosophoic sets to generalize the theory of fuzzy sets. In this paper we modify the definition of neutrosophic normed space with help of continuous neutrosophic t-representable norm. Then we study the statistical graphical
