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.

Hesitant Fuzzy Soft Sets with Application in Multicriteria Group Decision Making Problems

TL;DR: Wang et al. as mentioned in this paper proposed a multicriteria group decision-making approach with hesitant fuzzy soft sets and four aggregation operations, such as the HFSWA, HFSWG, GHFSWA and GHFS WG operators.

On Soft Rough Topology with Multi-Attribute Group Decision Making

TL;DR: This paper develops the topological structure on soft rough set by using pairwise SR -approximations and applied an algorithm based on SR -set to multi-attribute group decision making (MAGDM) to deal with uncertainty.
