1.4.1 Reliability Metrics for a Technical Item
ОглавлениеCommon reliability metrics for an item include
1 The mean time‐to‐failure (MTTF)
2 The number of failures per time unit (failure frequency)
3 The probability that the item does not fail in a time interval (survivor probability)
4 The probability that the item is able to function at time (availability at time )
These and several other reliability metrics are given a mathematical precise definition in Chapter 5, and are discussed and exemplified in all the subsequent chapters.
