| 摘 要： | 根据粒计算思想提出了一种从不完备决策表中分层提取确定规则的方法,将决策表进行分解,然后按决策表提供的确定信息分层提取相应的确定规则,在处理过程中认为空值提供的信息是不可靠的,所以与确定值严格加以区分,该方法充分利用不完备信息系统中的确定信息,得到长度不等的确定规则。

| Abstract: | An algorithm of rule acquisition from incomplete information systems is proposed based on granular computing.The in-formation table is decomposed to hierarchy.Certain rule will be acquired according to certain information in every hierarchy.Because the null value is uncertain,it is regarded not equal to any certain value in processing. |
