摘要： 提出了一种基于修正容差关系的扩充粗糙集模型。该种模型既保留了限制容差关系扩充模型的优点,又丢弃了容差关系、相似关系和限制容差关系扩充模型的不足。通过实例,说明了基于修正容差关系的扩充粗糙集模型对处理不完备信息系统更加简便有效。

Abstract: In this paper,a new extension of rough set based on modified tolerance relation is presented.Not only does the extension reserve the advantage of limited tolerance relation,but also it deserts the disadvantage of tolerance relation,similarity relation and limited tolerance relation.By an example,it is verified that the extension of rough set based on modified tolerance relation is more convenient and effective than the previous extensions in practice.
