A system consists of two subsystems, "A" and "B". Subsystems A and B have the same MTBF. The MTTR of subsystem A is 0.5 hours. The MTTR of subsystem B is 1.5 hours. Given the equal subsystem failure rates, the system MTTR is calculated by taking the average of the subsystem MTTRs, resulting in a system MTTR of 1.0 hour.
