MTBF & MTTR

KPIs, measured in seconds, which indicate, respectively, the reliability and maintainability of a plant or machinery.

MTBF (Mean Time Between Failure)

The average time between the occurrence of one failure and the start of the next. The higher it is, the more reliable the machinery is.

MTTR (Mean Time To Repair)

The efficiency of maintenance service. The lower it is, the more responsive maintenance is in solving problems.
