As an important quantificational index for maintainability, the predication method and algorithm of mean time to repair ( MTTR) are always dependent on experimentation and experience. 平均修复时间(MTTR,MeanTimetoRepair)作为一个重要的维修性定量指标,目前其预计方法及算法立足于大量的试验结果和经验估计。
By concentrating on Mean Time to Repair ( MTTR) rather then Mean Time to Failure ( MTTF), we find that quick recovery reduces recovery time and thus offers higher availability. 通过关注平均修复时间,而不是平均故障时间,发现快速的恢复减少了恢复时间,因而提供了更高的可用性。
