摘要
余度容错技术是随着计算机系统可靠性的需求而产生和发展的。为了避免共性故障的产生,实现飞控计算机系统各性能指标,研究非相似双余度飞控计算机系统结构。应用广义随机Petri网建立该飞控计算机系统的模型,利用马尔可夫链来计算和分析该系统的可靠性,在分析结果的基础上,提出系统研究方案的可实施性。
Redundancy fanlt-tolerant technology has emerged and developed with the need of computer system reliability. In order to avoid the correlated faults and realize the performance indexes of flight control computers, the architecture of the dissimilar dual-redundancy flight control computer system is researched. Generalized stochastic Petri net （GSPN） is applied to set up the model of flight control computer system, Markov is used to calculate and analyze the reliability of the system. And practical research approach is proposed based on the analysis results.
