基于GSPN的车电系统可靠性建模与分析

摘要

Based on the analysis of fault patterns of Integrated Vetronics Systems (IVS), Generalized Stochastic Petri Net(GSPN) is used as a theory tool and a new reliability model of IVS based on GSPN is proposed. The dynamic curves of availability are obtained by simulation experiment and the affect of every subsystem on the whole availability of IVS is analyzed. The proposed model can provide theoretical reference for analysis, design and optimization of reliability in IVS.%在深入分析车电系统故障模式的基础上,以广义随机Petri网为理论工具,提出一种基于GSPN的车电系统可靠性模型.通过仿真实验得到了系统可用度指标的动态变化曲线,分析了各个功能子系统对车电系统整体可用度的影响.该模型可为新型车电系统可靠性的分析、设计与优化提供理论依据.
