For reasoning advantage with Bayesian network theory in resolving the uncertain events, a new damage assessment method is proposed to military engineering with Bayesian network. As the system characteristics and requirements to protection engineering damage assessment, system modeling approach is put forward with decomposition,conversion and integrated rules, system analytical framework is established for modeling in military engineering damage assessment after the introduction of Bayesian network theory. On the basis of determining the network nodes variable to military engineering damage assessment,network structure and parameters are determined with simulation data,which are used to find the implied probability of dependency relationships and knowledge representation,the confidence model is built in military engineering damage evaluation. An example verifies the validity in damage assessment and reasoning with Bayesian network.%应用贝叶斯网络理论在解决不确定性事件方面的推理优势,提出了基于贝叶斯网络的军事工程毁伤评估新方法.根据军事工程毁伤评估的系统特征与要求,提出了分解、转换、综合的系统建模规则,并引入贝叶斯网络原理,建立了运用贝叶斯网络进行军事工程毁伤评估系统建模的分析框架;在确定军事工程毁伤评估网络节点变量的基础上,以仿真计算数据为样本,确定网络结构和网络参数,寻找隐含的概率依赖关系和知识表达,构建军事工程毁伤评估置信模型.通过实例验证了用贝叶斯网络进行军事工程毁伤评估与推理的有效性.
