| Abstract: | 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. |
