摘　　要：威胁估计是基于客观事实和规则的因果推理判断,而贝叶斯网络提供了一种自然的表示因果关系的手段。通过对威胁估计过程的理解,全面分析了影响威胁等级的评估参数,建立了威胁估计的贝叶斯网络模型,并采用动态贝叶斯网络推理方法进行威胁估计。实例仿真结果验证了该方法的实用性和有效性。Threat assessment is an inference based on the truth and rules,and that Bayesian network provides a method for natural casual description.After comprehending the process of threat assessment,evaluation parameters are studied completely and the model of dynamic Bayesian network is constructed.Based on the model,a recursive inference algorithm of dynamic Bayesian network is used to calculate the threat values.The simulation shows that the methodology is not only practicable but also effective.
