软集理论是1999年Molodtsov为了克服传统数学在处理不确定性问题时所遇到的困难而提出的一种新的数学工具。将软集理论与Z.Pawlak粗糙集结合起来,提出了软模糊粗糙集和软模糊粗糙群及它们的同态的概念,讨论了它们相关的性质。
The theory of soft set theory is introduced by Molodtsov in 1999 in order to deal with uncertainties which traditional mathematical tools cannot handle. In this paper, the soft set theory is applied to the theory of rough set introduced by Z.Pawlak. The notions of soft fuzzy rough sets and soft fuzzy rough groups and the notions of their homomorphisms are presented and some related properties are discussed.
