摘要： 提出一种基于故障树模型的诊断方法，并基于该方法实现了一个验证性的诊断系统。基于故障树的层次诊断模型，提出了确定性推理方法和可能性推理方法及面向故障树的基于框架和广义规则的混合知识表示方法。最后在ＣＯＭ－ＰＡＱ４８６微机上，Ｗｉｎｄｏｗｓ环境下，用ｂｏｒｌａｎｄＣ＋＋实现了该诊断系统，并通过对一个电路系统实验台的诊断验证了方法的有效性。

Abstract: The paper presents a diagnosis method based on fault tree model andrealizes a diagnostic system. First, a hierarchical diagnosis model is presented and acertain reasoning strategy and a possible reasoning strateyg are proposed. Secondly, afault tree-objected and frame and generalized rule based hybrid knowledge representation method is presented. Finally, the diagnostic system is realized in BORLANDC+ +, using COMPAQ 486 with WINDOWS operating platform, and demonstrated bydiagnosing a circuit testbed.
