摘　　要：针对导航系统动态可靠性分析问题,讨论了基于Monte Carlo仿真的动态可靠性事件序列采样方法,给出了Shannon信息熵采样准则;以SimPRA软件为分析平台,建立了导航系统动态可靠性仿真模型,并完成了导航系统的动态可靠性分析。仿真分析结果验证了动态可靠性分析的优越性及可行性。It focuses on the dynamic reliability assessment of navigation system. Firstly, the sampling cri- terion of the scenarios was studied based on the Monte Carlo simulation and the sampling criterion was given by calculating Shannon information entropy. Then the model of the dynamic reliability of navigation system was built based on SimPRA （simulation-based probabilistic risk analysis）and finished the dynamic reliability analysis. The results show that dynamic reliability assessment is advantage and effectiveness in engineering.
