摘　　要：对容错计算机系统的可靠性进行评估是一项重要而困难的工作。为容错计算机系统的各个组成部件建立了部件级故障模型,并以此为基础建立了整个容错计算机系统的可靠性测评模型。基于所建立模型,我们提出了分布式仿真的思想,它把系统的各个部件仿真为网络上的一个站点,并增设一台服务器来对整个系统的可靠性性能进行统计和分析。仿真结果验证了建立模型的正确性和方法的有效性。Evaluation for reliability of fault-tolerant computer systems is important and difficult. The paper first describes the failure model for components of computer system. Then the evaluation model of the whole system is established. Based on the established failure model, a distributed simulation model is given,which uses one computer to emulate one component and a server to process data of the whole system. The computers and the server are connected by a network, they corporate to finish the emulation of the whole fault-tolerant computer systems. Numerical results verify the validity of the evaluation model and effectiveness of the emulation method.
