| 摘 要： | 惯导系统的安全性是影响整个飞行器安全的重要因素.在利用动态故障树对惯导系统进行安全性分析时,针对马尔科夫链的组合爆炸和无法分析事件服从非指数分布系统的问题,引入了Monte - Carlo方法.提出了一种基于改进的最小割集的动态故障树分析方法,该方法通过改进最小割集的生成方法,确定相应的分析流程,综合了二元决策图、马尔...

| Abstract: | The security of inertial navigation system is the key factor to determine the safety of missile.During the adoption of the dynamic fault tree(DFT) to analyze the security of inertial navigation system,Markov chain has the state explosion problem and is only applicable in the case of exponential distributions,Monte-Carlo method is introduced to solve those problems.An improved approach based on the minimal cut-sets is proposed,through ameliorating the method of minimal cut-sets generation and determining app... |
