Abstract: Rough set algebra is portrayed in rough set theory which is an important direction of research. This paper in the form of a collection of [R(X),R(X)] defines binary operation[*]. It is proved that the set of the sequence accidentally constitutes a bounded BCK algebra. This paper also gives the basic nature, and lays a foundation for rough logic and reasoning.

Key words: Rough Set, upper approximation set, lower approximation set, BCK algebra

摘要: 粗糙集的代数刻画是粗糙集理论中研究的一个重要方向,在偶序对[R(X),R(X)]构成的集合中定义了二元运算[*],证明了序偶对构成的集合构成了一个有界BCK代数,给出了基本的性质,为粗糙逻辑和粗糙推理奠定了基础。
