Tasks are performed sequentially MTBF is used in the calculation of the Availability, which in turn is used to calculate overall equipment effectiveness (OEE): Example: Series system (most packing lines) Availability of an individual plant item (series system) Av 1 = 1 – MTTR/(MTBF + MTTR) (Where MTTR = mean time to repair = average time to return a failed component to service) MTBF = MTTF + MTTR. The title should be “TTR is more important than TBF (for most types of F)” Why?Because taking the statistical mean of TTR or TBF makes absolutely no sense, whatsoever.Incidents and events simply are not comparable in that way, and even if they were, the time an event starts is infinitely negotiable. MTBF, or Mean Time Between Failures, is a metric that concerns the average time elapsed between a failure and the next time it occurs. Rate of occurrence of failure (ROCOF) It is the number of failures appearing in a unit time interval. Mean time to repair is most commonly represented in hours. save Save MTBF-MTTF.ppt For Later. Maintenance time is defined as the time between the start of the incident and the moment the system is returned to production (i.e. Article by Stephen Foskett. Thus, an MTBF of 300 denoted that once the failure appears, the next failure is expected to appear only after 300 hours. MTBF data should be a required line item in an RFQ (Request For Quote).
