| 摘 要： | 为建立可变工作环境下分布式系统可靠性模型，提出受控混合随机Petri网，即用连续库所中的托肯控制离散变迁的变迁率．以此反映工作环境对部件可靠性的影响，从而推理出环境对系统可靠性的影响．在此模型的基础上，采用蒙特卡罗方法进行不同环境下系统可靠性仿真求解，解决了可变工作环境下分布式系统的可靠性建模及其分析问题．最后，以一个C^4ISR系统为例说明了该方法是一种考虑可变工作环境影响的分布式系统可靠性分析的可行方法．

| Abstract: | In order to build a system reliability model which works in variable stochastic Petri net is proposed. It uses tokens in continuous places to control the reflects the effect of work environment to the component reliability. Thereby the wo system reliability is expressed. Based on this model, Monte Carlo method is used system reliability in different environment. Reliability modeling and analysis of dis environment, controlled hybrid environment are solved. Finally, a C4 ISR system illuminates feasibility of this method. |
