Optimal Replacement Policy for the F-15 Aircraft Engine Modules

Abstract

The F-100 engine, used on the F-15 aircraft, differs from previous engines in that it is modularized. Certain of the engine modules must be removed in order to perform maintenance on others. As an example, the fan module must be removed to repair the core module. If an unfailed module is removed to facilitate maintenance on another module, it may be worthwhile to replace the unfailed module rather than reinstall it. Such a replacement is termed opportunistic maintenance. The purpose of the study was to determine if an algorithm could be developed which would determine when opportunistic replacement is optimal and when it is not. An algorithm was developed and programmed in FORTRAN. Variables addressed include transportation, packing, manpower, parts, depot overhaul costs and module failure tests.
