摘要
通过覆盖粗隶属函数,将粗糙集理论与模糊集理论联系起来,建立一种粗糙集理论与模糊集理论间的关系.把覆盖粗隶属函数视为论域上的一个特殊模糊集,用它的α-截集和β-强截集的概念,将覆盖粗糙集模型进行推广,提出基于邻域的隶属度的覆盖粗糙集模型,并讨论了其性质.
Combining fundamental concepts and properties in fuzzy and rough set theories, a model of membership degree coveting rough sets is established in this paper. Notions of α-cut sets and β-strong cut sets are defined and used to generalize the trandifional model of coveting rough sets with the aid of the concept of neighborhood. Some properties of this model are discussed.
