MTTR stands for Mean Time To Repair and MTBF stands for Mean Time Between Failures.

• MTTR is the average time taken to repair a failed component or system.

• MTBF is the average time between failures of a component or system.

• MTTR is usually measured in hours or days, while MTBF is also measured in hours or days.

• MTTR is an important metric for assessing maintenance efficiency, while MTBF is used to predict the reliability of...read more

MTTR (Mean Time to Repair) measures repair time, while MTBF (Mean Time Between Failures) measures operational uptime.

• MTTR is the average time taken to repair a system after a failure occurs.

• MTBF is the average time between consecutive failures of a system.

• For example, if a machine fails and takes 2 hours to repair, its MTTR is 2 hours.

• If a machine operates for 100 hours and fails 5 times, its MTBF is 20 hours (100 hour...read more
