Let stage i have direct success probability .
The passage around this formula
An agent can recover only if the system generates a discriminating observation. Let stage i have direct success probability . If failure occurs, let be the probability it is detected, the probability the cause is diagnosed correctly, and the probability repair succeeds without creating another material defect. A simplified effective stage reliability is
