【摘要】 从粗糙集中的"边界"(可能决策)的角度出发,首次提出了上(下)边界的概念,讨论了边界的一些性质,进而提出了粗糙问题中可近似为精确问题处理的近似精确问题模型,并给出了近似精确问题的处理方法.更多还原

【Abstract】 Concepts of R-inside boundary and R-outside boundary in rough sets are defined in this paper and some properties of R-boundary are discussed. Then approximately definable rough problems in rough sets are presented and solved by approximate method.更多还原
