A formalism for analyzing the reliability R of an interval for system probability of failure and its confidence C from the component R-C intervals is outlined as follows: Obtain the network representation of the system, in which the (dependent) path failure probabilities are indicated relative to their component failure probabilities. Derive by an algorithm such as STOP a representation of the system by disjoint paths and their state probabilities. The system probability of failure is a sum of these. Declare an R-reliable interval for each component probability of failure and express a confidence in that interval. For a declared R-reliable interval for system probability of failure derive the confidence in that interval. This general formalism is developed with reference to aircraft engine component retirement-for-cause.
