| 摘 要： | 提出了一种基于有向图的FBS-因果模型，对FBS-因果模型的形式化描述、建模步骤进行了详细研究，对模型的有关假设、定义及其应用范围等进行了分析，总结性地给出了2种基本的故障诊断策略：序贯测试确定性故障修复法和最大后验概率候选故障源更换法。最后对抽象实例进行验证，结果表明基于有向图的FBS-因果模型的故障诊断测试是实用的，也是有效的。

| Abstract: | In this paper, a Functional Behavior ＆ Structure Causal Diagraph Model （FBSCDM） is presented. First the FBSCDM formalization, modeling procedure and the model＇ s and condition, definition and field of application are studied ; then two fundamental fault diagnosis strategies generalized ： sequencing diagnosis definite faulty recovery method and most posterior probability suspected fault set replacement method. Finally according to an illustration, it is proved that the FBSCDM is practical, and effective for fault diagnosis test modeling. |
