Asset Reliability
Mean Time Between Failures (MTBF)
The fundamental metric of asset reliability predicting the expected operating duration between machine failures.
Mathematical Formula
Standard Formula
Total Operating Uptime Hours / Number of Unplanned Breakdown Failures
World-Class Industry Benchmark:
Higher is better. World-class targets exceed 800 to 1,200 operating hours for discrete manufacturing cells.
