摘要
文章讨论了一个带表决机的三重冗余(TMR)计算机的硬件-软件系统。假定系统的三个相同的处理机及表决机的寿命均服从指数分布,软件系统的失效率是与软件系统残留错误数有关的一个常数,所有的修理时间服从一般分布。从而求得了感兴趣的可靠性指标。
in this paper the reliability of a triple modular redundant (TMR) computer hardwaresoftware system taking account of voter's failure is analysed. It is assumed for the system that the lifetimes of each processor and the voter obey exponential distributions,the software system failure rate isa constant which depends on the remaining errors,and the repairtimes of hardware and software systemobey arbitrary distributions. Some useful reliability measures are given.
