Roughness of fuzzy soft sets and related results [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2015
This paper investigates roughness of fuzzy soft sets. A pair of fuzzy soft rough approximations is proposed and their properties are given. Based on fuzzy soft rough approximations, the concept of fuzzy soft rough sets is introduced.

Possibility Fuzzy Soft Set [PDF]

open access: yesAdvances in Decision Sciences, 2011
We introduce the concept of possibility fuzzy soft set and its operation and study some of its properties. We give applications of this theory in solving a decision-making problem. We also introduce a similarity measure of two possibility fuzzy soft sets and discuss their application in a medical diagnosis problem.

Interval-Valued Fuzzy Parameterized Intuitionistic Fuzzy Soft Sets and Their Applications

open access: yesCumhuriyet Science Journal, 2019
In recent years, the fuzzy sets, interval-valued fuzzysets, intuitionistic fuzzy sets and soft sets, which offer differentperspectives for the structures containing the uncertainties, have attractedthe interest of many researchers.

Using nonstationary fuzzy sets to improve the tractability of fuzzy association rules [PDF]

open access: yes, 2013
Modern organisations now collect very large volumes of data about customers, suppliers and other factors which may impact upon their business. There is a clear need to be able to mine this data and present it to decision makers in a clear and coherent ...

Some geometrical methods for constructing contradiction measures on Atanassov's intuitionistic fuzzy sets [PDF]

open access: yes, 2011
Trillas et al. (1999, Soft computing, 3 (4), 197–199) and Trillas and Cubillo (1999, On non-contradictory input/output couples in Zadeh's CRI proceeding, 28–32) introduced the study of contradiction in the framework of fuzzy logic because of the ...

Intuitionistic Fuzzy Topology on Soft Sets

open access: yesProceedings of the Institute of Mathematics and Mechanics, National Academy of Sciences of Azerbaijan, 2021
Summary: The purpose of the paper is to define intuitionistic fuzzy topology (co-topology) \((\tau, \tau^\ast)\) and examine some of its important properties. To do this, we firstly provide some fundamental properties of soft sets. Later in the paper, we introduce the concepts of base and subbase in intuitionistic fuzzy topological space of soft sets.

THE CONSTRUCTION OF SOFT SETS FROM FUZZY SUBSETS

open access: yesBarekeng, 2023
Molodtsov introduced the concept of soft sets formed from fuzzy subsets in 1999. The soft set formed from a fuzzy subset is a particular form of a soft set on its parameter set. On a soft set formed from a fuzzy subset, the parameter used is the image of

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

open access: yes, 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).

New generalization of fuzzy soft sets: $ (a, b) $-Fuzzy soft sets

open access: yesAIMS Mathematics, 2023
<abstract><p>Many models of uncertain knowledge have been designed that combine expanded views of fuzziness (expressions of partial memberships) with parameterization (multiple subsethood indexed by a parameter set). The standard orthopair fuzzy soft set is a very general example of this successful blend initiated by fuzzy soft sets.
