WebJan 16, 2024 · MTBF = Number of hours of operational time / Total number of failures. Mean Time to Repair (MTTR) Mean Time to Repair (MTTR) applies only to repairable items … WebIf the MTBF is known, one can calculate the failure rate as the inverse of the MTBF. The formula for failure rate is: failure rate= 1/MTBF = R/T where R is the number of failures and T is total time. Once an MTBF is calculated, what is the probability that any one particular device will be operational at time equal to the MTBF?

WebJul 7, 2024 · How is MTBF and MTTR availability calculated? Availability 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.
