摘要
深入研究一般petri网建模理论的基础上,对petri网进行了改进,建立了改进petri的系统可靠性模型。在改进的可靠性模型中不考虑零件的强度退化,在最底层零部件运用广义应力-强度干涉模型获得最底层的零部件动态可靠度,通过底层零部件的动态可靠度计算整个系统的动态可靠度,最后通过实例证明了该方法的可行性和对系统动态分析的优越性。
On the basis of in-depth study of the general petri net modeling theory, petri net is improved, and the improved petri system reliability model is established. For the improved reliability model, the intensity degradation of the parts are not considered. The generalized stress-strength interference model are used in the bottom parts to test their dynamic reliability, and by which the dynamic reliability of the entire system is calculated. Finally, an example is used to prove the feasibility of the method and the superiority of the system dynamic analysis.
