| 摘 要： | 在基于模型的故障诊断中，并非由候选产生出的所有ｈｉｔｉｎｇ集都是真实的故障解，同时，各可能ｈｉｔｉｎｇ集的发生概率也不尽相同。为此，本文提出了一种对不可能ｈｉｔｉｎｇ集进行剔除及对可能ｈｉｔｉｎｇ集进行概率排序的诊断方法。

| Abstract: | In model based diagnosis,not all the hitting sets generated from candidates are the real fault results,and on the same time,the probabilities of different hitting sets are different.From this point,a method is presented to delete the impossible hitting sets and sequence the probability of possible hitting sets.The effectiveness and the accuracy for diagnosis are improved with the method,particulally in the case that the accuracy is given. |
