基于贝叶斯网络推理算法的故障注入技术应用

Fault injection technology based on Bayesian network inference algorithm

故障注入是测试性验证试验的关键步骤。针对被测对象中位置不可达的故障难以注入的问题,提出了一种基于贝叶斯推理算法-多树传播算法的故障等效方法,通过对某型坦克炮控系统常见故障的分析,得出位置不可达故障的等效故障,通过对等效故障进行注入,实现了对位置不可达的故障的注入,验证了方法的有效性。

Fault injection is a critical step in testability verification test. For the question that the fault can't reached in the object which would be measured,we proposed an equivalent method of the fault which based on Bayesian inference algorithm- Multi tree propagation algorithm,by analysis the Gun Control System common faults,we draw up the equivalent fault of the unreachable one,by injecting equivalent fault,we achieve injecting the unreachable one,the application shows the correctness of the method.
