A repairable system contains three components. Components 2 and 3 are in parallel and both are required for subsystem success. Component 1 is in series with the parallel combination of 2 and 3. If the system fails, no further failures can occur until the system is placed back in service. Lambda subscript 1 equals 0.3 space f divided by y r, lambda subscript 2 equals 0.5 space f divided by y r, lambda subscript 3 equals 3.5 space f divided by y r and mu subscript 1 equals mu subscript 2 equals mu subscript 3 equals 50 space r divided by y r.
