摘要
在基于随机集的粗糙上近似、粗糙下近似的概念及其简单性质的基础上,定义了随机近似空间上的粗糙度、基于随机集的粗糙集的上粗相等、下粗相等、粗相等、随机粗糙集类和随机粗糙近似空间的概念,并且得出了随机粗糙近似算子的一系列性质、随机粗糙集类和随机粗糙近似空间的一一对应关系等重要的结论。
In this paper, the roughness in random approximate space is defined; the upper-rough equivalent, the lower-rough equivalent, the rough equivalent are defined; the class of random-rough set and random-rough approximate space are also defined. At the same time, a series of important conclusions are drawn. All these definitions and conclusions are based on the definitions of the rough upper （lower） approximate depended on rough set and their simple properties.
