Identification and Classification of Multi-Attribute Decision-Making Based on Complex Intuitionistic Fuzzy Frank Aggregation Operators

open access: yesMathematics, 2023
Invented by Frank in 1979, Frank’s t-norm and t-conorm operations possess improved modifications and can be applied more generally than the existing algebraic t-norm and t-conorm.

Some New Structures in Neutrosophic Metric Spaces [PDF]

open access: yesNeutrosophic Sets and Systems, 2021
Neutrosophic sets deals with inconsistent, indeterminate and imprecise datas. The concept of Neutrosophic Metric Space (NMS) uses the idea of continuous t- norm and continuous t - conorm in intuitionistic fuzzy metric spaces.

Aczel Alsina t-norm and t-conorm-based aggregation operators under linguistic interval-valued intuitionistic fuzzy setting with application. [PDF]

open access: yesPeerJ Comput Sci
This article uses the Aczel-Alsina t-norm and t-conorm to make several new linguistic interval-valued intuitionistic fuzzy aggregation operators. First, we devised some rules for how linguistic interval-valued intuitionistic fuzzy numbers should work ...

On the relationship between positive semi-definite matrices and t-norms [PDF]

open access: yes, 2021
t-norms and t-conorms are the natural connectives “and” and “or” in fuzzy logic. The unit interval with a t-norm or a t-conorm is a special monoid and some submonoids like discrete t-norms and t-conorms have been proved useful in many cases. In the first

A novel study of spherical fuzzy soft Dombi aggregation operators and their applications to multicriteria decision making

open access: yesHeliyon, 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

Plithogenic sets and their application in decision making [PDF]

open access: yesNeutrosophic Sets and Systems, 2020
There are various mathematical tools available to measure the level of accuracy such as Crisp, Fuzzy, Intuitionistic fuzzy sets and Neutosophic set. Further, Plithogenic set is a generalization of these four sets.

RETRACTED ARTICLE: Distance and similarity measures for (p, q)-fuzzy sets and their application in assessing common lung diseases

open access: yesSN Applied Sciences, 2023
This paper aims to develop distance and similarity measures for (p, q)-fuzzy sets from t-norms and t-conorms. It showcases a way to generate these measures from a given t-norm or a t-conorm operator. These newly developed distance and similarity measures

Complex interval-valued intuitionistic fuzzy decision support system with application to COVID-19 healthcare facilities

open access: yesComplex & Intelligent Systems, 2023
The complex interval-valued intuitionistic fuzzy set (CIIFS), as an extension of the complex intuitionistic fuzzy set (CIFS), is one of the better tools for dealing with time-periodic information in a single set of two-dimensional information.

On Intuitionistic Fuzzy Metric Space and Ideal Convergence of Triple Sequence Space [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2023
The purpose of this article is to introduce the triple sequences and its convergence over instuitionistic fuzzy metric space (\textbf{IFMS}). The article also discusses ideal convergence of triple sequences, the uniqueness of ideal limits, the ...

George-Veeramani Fuzzy Metrics Revised

open access: yesAxioms, 2018
In this note, we present an alternative approach to the concept of a fuzzy metric, calling it a revised fuzzy metric. In contrast to the traditional approach to the theory of fuzzy metric spaces which is based on the use of a t-norm, we proceed from a t ...
