基于本体论与贝叶斯式网络的舰炮武器系统故障诊断方法研究

摘要

针对舰炮武器系统在故障诊断过程中存在不确定性以及新故障知识不易添加的问题，提出了一种将本体论与贝叶斯网络相结合故障诊断方法。利用本体的知识表示方法建立关于舰炮武器系统的本体模型，然后将此模型转化为贝叶斯网络模型，最后利用贝叶斯网络进行舰炮武器系统故障方面的不确定性推理。利用此方法可以有效解决舰炮武器系统复杂故障现象问题。%Against the problem of nodeterminacy and new fault knowledge is not easy to add in the process of fault diag‐nosis ,a new method is put forward by combining ontologies and bayesian network .The representation of ontology knowl‐edge is used to built the ontology model about the naval gun weapon system .Then this model is converted into a bayesian network model .Finally the bayesian network is used for naval gun weapon system failure of uncertainty reasoning .This method can effectively solve the problem of complex naval gun weapon system fault phenomenon .
