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.

Comparison of the concepts of soft set, fuzzy soft set and L-fuzzy set

2011 Eighth International Conference on Fuzzy Systems and Knowledge Discovery (FSKD), 2011
This paper consists of two related but independent parts: (1) Characterizing separation axioms of topological spaces with soft sets. (2) Comparing the concepts of soft set, fuzzy soft set and L-fuzzy set.

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

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 ...

Note on fuzzy soft sets and fuzzy soft lattices

Revista de la Real Academia de Ciencias Exactas, Físicas y Naturales. Serie A. Matemáticas, 2017
In this note, we point out that several assertions (Proposition 7, Lemmas 20, 21 and Theorems 7, 15) in [Y. Shao and K. Qin, Fuzzy soft sets and fuzzy soft lattices, Int. J. Comput. Intell. Sys. 5 (2012), 1135–1147] are not true in general. Appropriate counterexamples are given. Further their modified versions are presented.

Hesitant fuzzy parameterized hesitant fuzzy soft sets and their applications in decision-making

International Journal of Computational Mathematics, 2021
A hesitant fuzzy set is a significant tool to model disagreements of the decision-makers over a subject. Also, the notion of the soft set is another useful instrument in the modelling of some problems.

Logic Connectives for Soft Sets and Fuzzy Soft Sets

IEEE Transactions on Fuzzy Systems, 2014
Collections of soft sets and fuzzy soft sets are complete modular lattices with respect to certain binary operations. Therefore, logic connectives such as Triangular norms, Triangular conorms, and implications may be studied for them. A major hurdle in this study is that soft sets and fuzzy soft sets are not sets and fuzzy sets, respectively. Actually,

Approaches that take into account interactions between parameters: pure (fuzzy) soft sets

International Journal of Computational Mathematics, 2021
This paper focuses on mathematical models constructed using parameterization tools. The existence of possible interactions between the elements of the parameter set expressed for such mathematical models directly affects the decision-making process.

Application of fuzzy sets and fuzzy soft sets in hypermodules

Revista de la Real Academia de Ciencias Exactas, Fisicas y Naturales. Serie A. Matematicas, 2012
In this paper, we apply fuzzy soft sets and fuzzy sets to algebraic hyperstructures to define soft hypermodules and fuzzy soft hypermodules. We will proceed to study their structural properties under operations such as union, intersection and “AND”. Also, Some of results about the level soft sets of fuzzy soft hypermodules are investigated.

Another View on Generalized Intuitionistic Fuzzy Soft Sets and Related Multiattribute Decision Making Methods

IEEE transactions on fuzzy systems, 2019
The existing definition of generalized intuitionistic fuzzy soft sets (GIFSSs) is clarified and reformulated as a combination of an IFSS over the universe of discourse and an intuitionistic fuzzy set in the parameter set.
