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. 收起
