摘要：
As a technique for granular computing, rough sets deal with the vagueness and granularity in information systems. Covering-based rough sets are natural extensions of the classical rough sets by relaxing the partitions to coverings and have been applied for many fields. In this paper, a new type of covering-based rough sets are proposed and the properties of this new type of covering-based rough sets are studied. First, we introduce a concept of inclusion degree into covering-based rough set theory to explore some properties of the new type of covering approximation space. Second, a new type of covering-based rough sets is established based on inclusion degree. Moreover, some properties of the new type of covering-based rough sets are studied. Finally, a simple application of the new type of covering-based rough sets to network security is given.
