基于半马尔可夫模型的民用机载容错系统可靠性分析

Reliability Analysis for Fault-Tolerant Systems of Civil Airborne Systems based on Semi-Markov Model

基于容错技术设计的民用机载系统可以达到高可靠性,而采用了大量的冗余配置及重构技术,使得该可靠性模型往往变得相当复杂。传统的故障树分析方法已经不适用。利用半马尔可夫过程理论对基于容错技术设计的机载系统进行可靠性建模,并对系统可靠性模型进行必要的化简,可以减少许多计算量并使该模型更加符合实际使用要求。

Civil airborne systems based on fault-tolerant technology design can get a high level of reliability,but lots of redundance allocation and reconfiguration mechanism make reliability complicated severely.The traditional fault tree analysis method is not applicable.Using semi-Markov process theory to build reliability model for Civil airborne systems based on fault-tolerant technology design and simplifying model necessarily is in order to reduce amount of calculation,and it meets actual operating requirements.
