【摘要】 将用于事务处理操作的容错计算机抽象为由独立同分布部件组成的多态k-out-of-n:G系统,本文针对这一类事务处理型容错计算机建立系统模型,考虑系统在不同工作状态等级下维修率存在差异,利用状态转移方程推导得到系统可用度的表达式,进一步地提出基于故障注入的MTTR测试方法通过实地测量来获取不同工作状态等级下的系统维修率,并设计了故障集以及测试方法。更多还原

【Abstract】 Fault-tolerant computers used for transactions processing can be abstracted as multi-state k-out-of-n:G system which consist of independent identical distribution components.Such kind of transactions processing fault-tolerant system is modeled in this paper with considering the difference of maintenance rates at different working state levels.An availability deduction method is proposed based on state transition equations.A MTTR measurement method based on fault injection technique is proposed to gain maintenance rates and the fault set and test method is designed as well.更多还原
