| 摘 要： | 本文在覆盖广义粗糙集最简覆盖的基础上,应用等域关系,将覆盖广义粗糙集转化为Pawlak经典的粗糙集,使得经典粗糙集理论的应用范围得到了一定的扩充,并用例子说明该转化方法提高了一个集合的近似程度.最后讨论了覆盖广义粗糙集与证据理论之间的关系.

| Abstract: | Based on the most reduced coverage of the generalization covering rough set,the equal domain relation is used to transform the generalization covering rough set into the classical ones so as to extend their applications of rough set theory further.An exemplification is given to show that this transformation method can improve the approximation level of a set.Then the Connections between Covering generalization rough set and theory of Dempster-Shafer evidence is discussed. |
