Operate Two Out of Three Machines


Multiple Machine Operation Logic with Preventive Maintenance and Different Failure Modes


This model illustrates logic to keep two out of three reliability components (e.g., machines) operating at any given time, while evening out the overall operating time among three machines. Each component includes four types of Preventive Maintenance (PM) schedules as well as random failure modes with auto-repair. PM can occur only when there are two operable machines.
