TLDR
The main purpose of this paper is to introduce the basic notions of the theory of soft sets, to present the first results of the the theory, and to discuss some problems of the future.Abstract:
The soft set theory offers a general mathematical tool for dealing with uncertain, fuzzy, not clearly defined objects. The main purpose of this paper is to introduce the basic notions of the theory of soft sets, to present the first results of the theory, and to discuss some problems of the future.read more

Generalization of Soft Set Theory: From Crisp to Fuzzy Case
TL;DR: The traditional soft set theory is expanded to be a fuzzy one, the fuzzy membership is used to describe parameter-approximate elements of fuzzy soft set and the DeMorgan’s laws are proved.

q‐Rung orthopair fuzzy soft average aggregation operators and their application in multicriteria decision‐making
TL;DR: This manuscript investigates the notion of q‐rung orthopair fuzzy soft set (q‐ROFSfS), which provide a lay of foundation for those difficulties and complexities which the contemporary theories face during the study of uncertainty.

An approach to fuzzy soft sets in decision making based on grey relational analysis and Dempster-Shafer theory of evidence
TL;DR: An approach to fuzzy soft sets in decision making by combining grey relational analysis with Dempster-Shafer theory of evidence is introduced and a practical application to medical diagnosis problems is given.

Generalized intuitionistic fuzzy soft power aggregation operator based on t-norm and their application in multicriteria decision-making
Harish Garg,Rishu Arora +1 more
TL;DR: This paper utilized some new power aggregation operators for intuitionistic fuzzy (IF) soft numbers to develop an approach to solve the decision‐making problem under IF soft set environment and demonstrated with an illustrative example.

Dual Hesitant Fuzzy Soft Aggregation Operators and Their Application in Decision-Making
Harish Garg,Rishu Arora +1 more
TL;DR: From the study, it is concluded that the proposed approach provides a more practical nature to the decision-maker during the aggregation process and hence demonstrate that they place an alternative way for solvingThe decision-making problems.
