摘要
应用双模型混合Petri网描述与分析容错计算机系统。在分析容错系统的可靠性时,把复杂的混合Petri网模型简化为GSPN模型,并利用GSPN与马尔可夫链同构的性质,来计算系统的可靠性。
Hybrid Petri nets is used to describe and analyse the fault-tolerant computer systems. By using HPN, static architectures of the fault-tolerant computer systems and dynamic behaviors of fault generation and promulgation are properly described, and the effect of transient error on reliability analysis of fault-tolerant computer systems can also be eliminated. The HPN model is simplified to GSPN model, and then GSPN model is converted to Markov chain to calculate the reliability of the systems.
