**Mean time between failures**— (MTBF) is the predicted elapsed time between inherent failures of a system during operation.[1] MTBF can be calculated as the arithmetic mean (average) time between failures of a system. The MTBF is typically part of a model that assumes the… …2

**Mean time between coincidences**— The mean time between coincidences (MTBC) is used in safety engineering and is defined as the reciprocal of the average frequency of dangerous coincidences:MTBC=frac{1}{lambda {d = frac{2}{lambda mu au } …3

**Mean time between coincidences Formula**— The mean time between coincidences (MTBC) is used in safety engineering and is defined as the reciprocal of the average frequency of dangerous coincidences: Categories: Safety engineeringReliability engineeringEngineering stubs …4

**Mean time to repair**— For other uses, see MTTR (disambiguation). Mean time to repair (MTTR) is a basic measure of the maintainability of repairable items. It represents the average time required to repair a failed component or device.[1] Expressed mathematically, it… …5

**Mean time between outages**— In a system the mean time between outages (MTBO) is the mean time between equipment failures that result in loss of system continuity or unacceptable degradation. The MTBO is calculated by the equation, where MTBF is the nonredundant mean time… …6

**Mean time to failure**— No artical exists on Wiki, please create one. In short Mean Time to Failure (MTTF) is the time taken for a part or system to fail for the first time. A very brief formula for the Mean Time To Failure of an event which occurs with probability P is …7

**Mean time**— Time Time, n.; pl. {Times}. [OE. time, AS. t[=i]ma, akin to t[=i]d time, and to Icel. t[=i]mi, Dan. time an hour, Sw. timme. [root]58. See {Tide}, n.] 1. Duration, considered independently of any system of measurement or any employment of terms… …8

**Mean time**— Mean Mean, a. [OE. mene, OF. meiien, F. moyen, fr. L. medianus that is in the middle, fr. medius; akin to E. mid. See {Mid}.] 1. Occupying a middle position; middle; being about midway between extremes. [1913 Webster] Being of middle age and a… …9

**Mean time to first failure**— Mean time (to) first failure (MTFF, sometimes MTTFF) is a concept in reliability engineering. It describes time to failure for non repairable components like an integrated circuit soldered on a circuit board. .[1] For repairable components like a …10
