摘要
主要研究了双论域粗糙集在故障诊断中的应用。对故障类别与条件属性这两个论域的数据进行了相关性分析,从而得到了双论域下故障类别和条件属性之间的二元关系。另外,通过对双论域粗糙集的规则提取算法,分别获得了由故障类型导出条件属性以及由条件属性确定故障类型的规则。
In this article we study the application of the double-domain rough set in fault diagnosis. First of all,we get the binary relation between fault categories and condition attributes of the dual-universes by the correlation analysis. In addition,using the extraction algorithm of the rough set over dual-universes,we get two types of rules： one is to use the fault attributes to deduce the condition attributes,and the other is converse.
