Fuzzy soft sets and fuzzy soft groups

2008 Chinese Control and Decision Conference, 2008
In this paper we study Molodtsovpsilas notion of soft sets and fuzzy soft sets considering the fact that the parameters (which are words or sentences) are mostly fuzzy hedges or fuzzy parameters. We discuss fuzzy soft setspsila algebraic structure and give the definition of fuzzy soft group.

Retrieving the Missing Data From Incomplete Soft Set, Incomplete Fuzzy Soft Set and Incomplete Intuitionistic Fuzzy Soft Set

New Mathematics and Natural Computation, 2021
Dealing with an incomplete information has been a major issue in the theory of soft sets. In this paper, we have presented an approach to deal with incomplete soft set, incomplete fuzzy soft set and incomplete intuitionistic fuzzy soft set. For this purpose, we have introduced the notion of distance between two objects (parameters) which will be used ...

The relation between fuzzy soft set and integrative fuzzy set

2017 12th International Conference on Intelligent Systems and Knowledge Engineering (ISKE), 2017
Fuzzy set can be divided into single parameter or multi-parameter's ones with which to depict their fuzzy attributes. In references, it is usual defined in a single parameter universe and yet multi-parameter's ones often appears in so-called fuzzy relation.

Fuzzy soft set theory applied to BCK/BCI-algebras [PDF]

Computers and Mathematics With Applications, 2010
In the paper [P.K. Maji, R. Biswas, A.R. Roy, Fuzzy soft sets, J. Fuzzy Math. 9 (3) (2001) 589–602], Maji et al. introduced the concept of fuzzy soft sets as a generalization of the standard soft sets, and presented an application of fuzzy soft sets in a

Rough Soft Sets in Fuzzy Setting

2013
Fuzzy set theory, soft set theory and rough set theory are mathematical tools for dealing with uncertainties and are closely related. In the paper, we define the notion of a soft set in L-set theory, introduce several operators for L-soft set theory, and investigate the rough operators on the set of all L-soft sets induced by the rough operators on L X

An algebraic result on fuzzy soft sets

2011 Eighth International Conference on Fuzzy Systems and Knowledge Discovery (FSKD), 2011
The concept of nested soft sets is proposed by extending the definition of nested sets. An equivalence relation is constructed on the set of nested soft sets. Then a novel algebra system is obtained and the union, intersection and complement operations of this algebra system are defined based on the equivalence classes of nested soft sets. Furthermore,

Spectral fuzzy sets and soft thresholding

Information Sciences, 1992
A new concept of spectral fuzzy sets has been introduced for dealing with the uncertainty in subjective assignment of membership value to the elements of a fuzzy set. The concept is characterized by a set of membership functions reflecting an individual's (or several individuals') opinion. The uncertainty due to spectralness has been explained.

Lattice Structures of Fuzzy Soft Sets

2010
In this paper, we study the algebraic structures of fuzzy soft sets. Some operations on fuzzy soft sets are introduced and several related properties are investigated. Furthermore, two lattice structures of fuzzy soft sets are established. It is proved that certain De Morgan's laws hold in fuzzy soft set theory.
