| 摘 要： | 动态重构系统安全机理分析的主要困难在于系统的复杂特性，这种复杂特性集中表现在动态重构系统功能主体的动态变化。这种动态变化导致了难以获得系统的安全机理，即导致危险产生的系统故障状态演变过程。首先分析了动态重构系统功能主体变化带来的多状态空间的分析问题；然后在多状态空间的问题基础上提出了一种危险引导的系统多元故障分析方法，从而分析系统安全机理，获得多状态空间下的系统故障状态演变过程。最后以动态重构航电系统为实例，对这种动态重构安全机理分析方法进行了应用说明。

| Abstract: | The key point of dynamic reconfiguration system safety mechanism analysis is the system complex characteristics. The characteristics are reflected in the dynamic change of the functional subject. This change leads to difficulty in obtaining the dynamic reconfiguration system safety mechanism which is the system failure state evolution process leading the system to hazard. This paper first analyzes the multi-state space problem caused by functional subject changing of the dynamic reconfiguration system. Then a hazard guided multi failure analysis method is proposed based on the problem above. This method could help analyze the system safety mechanism, and obtain the development process of system failure state. At last, a study on a dynamic reconfiguration avionic system is conducted to illustrate this system safety mechanism analysis method. |
