Availability, Reliability, Maintainability, and Capability

Reliability deals with reducing the frequency of failures over a time interval and is a measure of the probability for failurefree operation during a given interval, i.e., it is a measure of success for a failure free operation. It is often expressed as R(t) = exp(t/MTBF) = exp(λt)
