C3I系统中基于Petri网的可靠性仿真建模

C3I系统是一个复杂的可修系统,采用通常的解析法和马尔科夫过程法难以求出C3I所需的可靠性参数.故障树能够很好的对复杂系统的故障发生进行定性的分析,而随机Petri网(SPN)能够描述复杂系统状态变化的动态过程,并且能够按照概率进行定量的计算.因此提出将故障树转换为随机Petri网,建立C3I系统的可靠性仿真模型,就可以对C3I系统的可靠性进行定量与定性相结合的仿真.最后建立了一个简单的防空C3I系统可靠性的随机Petri网模型,用Monte-Carlo法仿真验证了该方法的正确性.

Reliability Modeling of C3I System based on Petri Net

C~3I system is a kind of complex repairable system.There are some limitations of usual analytic method and markov chain method.The fault tree analysis has the merit of qualitative analysis of the failure of the complex system.At the same time,SPN can describe the dynamic process of the transformation of the complex system's states,and can calculate the possibility of failures.So this paper put forward a new way to set up the simulation Model of C~3I by turned the fault tree into SPN.In the end,this paper establishes the SPN model of a simple C~3I system on aerial defence and simulates the model to validate the new way by the measure of Monte-Carlo.
