Construction of aggregation operators with noble reinforcement [PDF]

open access: yes, 2007
This paper examines disjunctive aggregation operators used in various recommender systems. A specific requirement in these systems is the property of noble reinforcement: allowing a collection of high-valued arguments to reinforce each other while ...

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.

Implication functions in interval-valued fuzzy set theory [PDF]

open access: yes, 2013
Interval-valued fuzzy set theory is an extension of fuzzy set theory in which the real, but unknown, membership degree is approximated by a closed interval of possible membership degrees.

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

Vague and fuzzy t-norms and t-conorms

open access: yesFuzzy Sets and Systems, 2022
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 part of this article these submonoids will be fuzzified to fuzzy t-subnorms and fuzzy t-subconorms ...

On sensible fuzzy ideals of BCK-algebras with respect to a t-conorm

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2006
We introduce the notion of sensible fuzzy ideals of BCK-algebras with respect to a t-conorm and investigate some of their properties. We give the conditions for a sensible fuzzy subalgebra with respect to a t-conorm to be a sensible fuzzy ideal with ...

RETRACTED ARTICLE: Distance and similarity measures for (p, q)-fuzzy sets and their application in assessing common lung diseases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

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 ...

Resolution in Linguistic Propositional Logic based on Linear Symmetrical Hedge Algebra [PDF]

open access: yes, 2013
The paper introduces a propositional linguistic logic that serves as the basis for automated uncertain reasoning with linguistic information. First, we build a linguistic logic system with truth value domain based on a linear symmetrical hedge algebra ...

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.
