The Impact of Maintainability Analysis on Aircraft Design

This paper describes an analytical model that may be used to determine the impact of maintainability (operational and resource requirements) on aircraft system design. The major advantage of analytical computer oriented models is the depth and detail of investigation that can be accomplished as a basis for design decisions. The model, designated SOURCE (Simulation of Utilization, Resources, Cost, and Efficiency), is designed to accept empirical data to determine realistically the interrelationships between maintainability and aircraft design characteristics.
