Web8 aug. 2024 · MTBF = Total operational time ÷ Total number of failures. Total operational time (Run time): = Planned production time – Stop time. (3600 hours – Stop time) = (3600- 458) =3142 hours. Now, Total Operational Time of last month = 3142 hours, Total number of failures of last month = 6 times. MTBF of last month = (3142÷6) hours.

Web20 sept. 2024 · 1 - Calculation of the mean time between failures (MTBF) The time lapses from one failure to the next can be calculated using the sum of the running time (uptime) divided by the number of failures. MTBF = Total uptime / # of Breakdowns. For example, out of an expected running time of ten hours, it ran for nine hours and failed for one hour ... WebAvailability measures both system running time and downtime. It combines the MTBF and MTTR metrics to produce a result rated in ‘nines of availability’ using the formula: Availability = (1 – (MTTR/MTBF)) x 100%. The greater the number of ‘nines’, the higher system availability. In mission-critical environments such as data centres ...
