✦ Synopsis

Two-unit series subject to shut-off rules have been treated before. For increasing system availability a new model is considered. The model is composed of a main subsystem which has two units and another secondary subsystem. When one unit of the main subsystem fails, then the other standby unit starts to operate. If both units of main subsystem are unoperable, then the main subsystem shuts off the secondary subsystem. For this model, the system availability is given by the Morkov renewal process. Then we obtain the mean inter-occurrence shut-off time and the steady-state probability that the system is under shut-off.
