Calculate the average time required to repair equipment or systems after a failure occurs. This helps in measuring system reliability and maintenance efficiency.
Learn how to use the Mean Time To Repair Calculator and understand its significance in maintenance planning
Mean Time To Repair (MTTR) is a key performance indicator in maintenance engineering. It represents the average time required to repair a system after a failure occurs. A lower MTTR indicates more efficient maintenance processes and better system reliability.
The formula used is:
MTTR = Total Downtime / Number of Failures
MTTR is crucial for:
If your equipment failed 5 times in a 100-hour period, and the total downtime was 12 hours, the MTTR would be 12/5 = 2.4 hours. This means, on average, it took 2.4 hours to repair each failure.
