QUEUING MODELS FOR ESTIMATING AIRCRAFT FLEET AVAILABILITY

The availability of a small fleet of aircraft in a flying-base, repair-depot combination is modeled and studied. A deterministic flow model relates parameters of interest and represents the state-of-the art in the planning of such systems. A cyclic queue model shows the effect of the principal uncertainties in operation and repair and shows the consequent decrease in the availability of aircraft at the flying-base. Several options such as increasing fleet size, investments in additional repair facilities, or building reliability and maintainability into the individual aircraft during its life-cycle are open for increasing the availability. A life-cycle cost criterion brings out some of these features. Numerical results confirm Rose's prediction that there exists a minimal cost combination of end products and repair-depot capability to achieve a prescribed operational availability.
