摘要
对覆盖广义Rough集中的隶属关系、隶属函数进行了定义,并利用隶属函数定义了集合的Rough包含与Rough相等,得到一些与Paw lak的Rough集不同的性质。
This paper defines membership relations and a membership function in covering generalized rough sets. Furthermore it defines rough inclusion and rough equality of sets through the membership function. Then we get some properties which are different from Pawlak＇s rough sets.
