Abstract: Considering the dynamic characteristics of the elements in singular rough sets,the concepts of inside boundary and outside boundary are defined.As discussing the character of inside(outside) boundary,the measure of relative precision is provided.At last,the approximate method which aims at dealing with system uncertainty is also given by example.

摘要: 针对S-粗集的动态特性,提出了内(外)边界的概念,讨论了内(外)边界的一些性质,给出了相对精度的度量,并举例说明了S-粗集系统不确定性的近似处理方法。
