Phased Mission Analysis of Maintained Systems. A Study in Reliability and Risk Analysis

摘要

A methodology that analyzes phased missions and all branches of an event tree and can take into account repair of the system during its mission and the effects of component models with general distributed lifetimes and repair times was developed. The introduction of the concept of period of a component makes it possible to separate the analysis of the system behavior from that of the component behavior. As a result the calculation of the probability of mission success is very simple. However, calculation of component unavailability becomes intricate, particularly if no negative exponentially distributed lifetimes and repair times are applied.
