一种求解最小故障集的集合运算推理方法

A Reasoning Method with Sets Computation Used for Solving Minimum Fault Sets

在基于模型的诊断推理中，诊断是分两步进行的，一是与领域有关的冲突识别，二是与领域无关的候选产生。本文定义了测点元件影响集的概念，提出了由测点元件影响集与测点的二值测量结果直接求解最小故障集合的方法。该方法与现有模型诊断方法完全不同，诊断只需一步完成。

In the model based diagnosis reasoning, the diagnosis is divided into two steps to proceed. One is conflict recognition with relation to the domain and the another is candidate generation without relation to the domain. In this paper, the concept of component sets affecting measurement points(CSAMP) is defined. By means of CSAMP and the two value measunement points, a method is presented to directly solve the minimum fault sets, which is quite different from the traditional model based diagnosis. The diagnosis is only finished in one step.
