Availability of Aircraft Subject to Imperfect Preventive Maintenance

This thesis studies the impact that imperfect preventive maintenance has on the availability of aircraft and, as a result, the decrease in operational effectiveness. We further consider the practicality of using an imperfect preventive maintenance model for determining preventive maintenance scheduling. Simulation was used to recreate the operational environment in order to study the effects that levels of imperfect preventive maintenance have on the aircraft during execution of an actual fleet tactic.
