介绍了地空导弹火力单元操作训练.给出了火力单元操作训练评估的贝叶斯网络模型.针对地空导弹火力单元操作训练实际,结合贝叶斯网络优点,建立了地空导弹火力单元操作训练的贝叶斯网络评估模型,并运用贝叶斯网络推理软件对模型进行推理,验证了模型的可信性. The operation training of surface-to-air missile fire unit is introduced.The Bayesian network model of fire unit operation training evaluation is given.According to the actual operation training of ground-to-air missile fire unit and the advantages of Bayesian network, Training Bayesian network assessment model, and use Bayesian network reasoning software to reason the model to verify the credibility of the model.
