可靠性可定义为可依赖性(dependability),国际电工委员会(IEC)将可依赖性定义为 "可用性性能及其影响因素:可靠性能、可维护性能和维护支持性能"。以前,人们通常用平均无故障时间(MTBF)来表示可靠性,而平均修复时间(MTTR)则表示可维护性,影响设备的效率。 可靠性的另一个定义是产品或系统执行其设计的特定功能的能力,...
MTBF 是一个广泛使用的指标,用于衡量设备故障之间的平均间隔时间。它说明了设备一般运行多长时间后才会出现故障。计算 MTBF 的方法是用总运行时间除以给定时间内的故障次数。MTBF 值越高,表示可靠性越高。 2. 平均修复时间(Mean Time to Repair ,MTTR) MTTR 衡量发生故障后修复设备所需的平均时间。它有助于企业评...

Mean Time Between Failure (MTBF) Failure in Time (FIT) Mean Time to Repair (MTTR) Mean Time to Failure (MTTF) Below you’ll find a synopsis of each of these measures. Mean Time Between Failure (MTBF) Mean Time Between Failure (MTBF) measures the amount of time...
MTBF is the inverse of failure rate. What is Mean Time To Restore (MTTR)? Total elapsed time from initial failure to the reinitiating of system status. Mean Time To Restore includes Mean Time To Repair (MTBF + MTTR = 1.) What is Root Cause Failure Analysis (RCFA)? A technique for ...

What are the Foundations and Benefits of Site Reliability Engineering? The basic principles of Site Reliability Engineering are easy to explain, but take some work to apply. We start with the foundational understanding that today's computer systems and platforms have an inherent complexity that is ...
