摘要
以基于邻域系统的粗糙集模型为基础,给出了邻域系统分层递阶结构的5条公理;提出了一种序关系,用来描述不同邻域系统之间的粗细关系;证明了新提出的这种序关系满足邻域系统分层递阶结构的公理化形式。
From the viewpoint of the neighborhood system based rough set, this paper presents five axioms to describe the hierarchical structure of the neighborhood systems. Moreover, it proposes a new order relation to describe the finer relation between different neighborhood systems. Finally, it proves that the proposed preference relation satisfies the five axioms of the hierarchical structure of the neighborhood systems.
