摘要
对于有人值守的可维修冗余显控系统,传统的静态可靠性建模分析方法容易忽略维修性与测试性对系统可靠性的影响.论文结合实际项目,采用动态建模分析方法对有人值守的同构双冗余热备显控系统进行建模与仿真分析,分析了故障检测覆盖率、维修率和共因失效率对热备显控系统可靠度的影响.仿真分析表明提高故障检测覆盖率、选择适中维修率、减少软硬件共因失效率,可以进一步加强冗余系统的可靠性.
Abstract
For manned repairable redundant display and control systems,traditional static reliability modeling and analysis methods tend to overlook the impact of maintainability and testability on system reliability.This article combines practical projects and uses dynamic modeling analysis method to model and simulate a manned isomorphic dual redundant hot standby display and control system.It analyzes the impact of fault detection coverage,maintenance rate,and common cause failure rate on the reliability of the hot standby display and control system.Simulation analysis shows that improving fault detection coverage,selecting moderate maintenance rates,and reducing software and hardware common cause failure rates can further enhance the reliability of redundant systems.
