| 摘 要： | 论文针对基于规则的故障源分离与定位方法中的一个关键问题,即诊断规则的获取,利用粗糙集的基本原理构造出了一种用于规则提取的新方法,其中包括了用于对故障决策表,即故障字典,进行属性约简的改进算法和属性值的顺序约简算法。该方法能够迅速从故障字典中提取出诊断规则,并揭示出故障信息内在的冗余性。最后实例应用的结果表明了该方法的有效性,尤其是在不完全信息情况下的有效性。

| Abstract: | The acquisition of diagnosis rules is a ke y problem in the rule-based distinction and location of fault sources.Aimed at t he above problem,a novel approach for rule acquisition based on rough sets theo ry is proposed.The improved algorithm for the attribute reduct and the orderly attribute value reduced algorithm are constructed on the fault decision table,i .e.fault dictionary,which can rapidly draw the diagnosis rules from the fault dictionary and reveal the inward redundancies in the fault information.Finally ,the experimentation show the effectiveness of the approach,es-pecially under incomplete information circumstances. |
