摘要
对于强实时双机系统，应该建立考虑影响系统可靠性因素较多的模型。本文，在给出可用度改进因子（ＡＩＦ）的定义基础上，建立了强实时双机系统的可靠性模型，用于综合考虑故障判别成功率（Ｃ）和故障判别时间（１／β）对系统可用度的影响，研究结果表明：应分别建立强实时和弱实时双机系统的可靠性模型，不能将二者混淆。
For hard real time Dual Computers System(DCS),considered more factors reliability models should be set up.In this paper,based on the definition of Availability Improvement Factor(AIF),the reliability model of hard real time DCS is presented,which can be integrated the effect of failure judge success rate and failure judge time on system reliability.The conclusions show:the reliability model of hard real time and soft real time DCS must be built separately,which can't be confused.
