| 摘 要： | 把一种基于贝叶斯网络的故障树分析法应用于飞控系统俯仰控制功能的可靠性评估中，突破传统故障树分析法的局限性——各部件独立、状态为二值，不但可以计算系统的可靠性指标，而且可以定量给出某个事件或某几个事件在系统可靠性中所占的地位，找出系统的薄弱环节。

| Abstract: | Researching the application of Bayesian networks to the reliability assessment of pitch channel of flight control system for the limits of traditional fault tree analysis method---components must be independent with two states. The new method can not only compute the reliability indices, but also quantitatively analyze the weights of certain components in the system reliability to find the vulnerable position in the system. |
