摘要
为了研究粗集理论中的六种不可区分关系间的联系与区别,将集对分析中的联系度引入到信息系统中,定义了对象与对象的联系度,计算出了当对象与对象间满足某种不可区分关系时它们所对应的联系度的取值,证明了可以用联系度来表示不可区分关系,还提供了一种用计算机来判断对象间是否具有不可区分关系的算法.
To study the connection and difference of six indiscriminate relations in rough set theory, we put connection degree in set pairs into information systems and define the connection degree between objects. The corresponding connection degree value is calculated if two objects have some indiscriminate relation. It is approved that the indiscriminate relation can be expressed by connection degree and the calculating method of using computer to judge whether there is indiscriminate relation is provided.
