This thesis presents a simulation metamodel that is used to determine initial rotable pool inventories for F404-GE-400 engine modules onboard a deployed aircraft carrier. Millions of dollars can be saved annually by following the metamodel recommendations for changes and reductions in inventories, while at the same time maximizing F/A-18 squadron operational availability. Managers and leaders in the naval aviation and supply communities should use the metamodel as a tool to modify F404 engine module inventory allowance requirements. The metamodel is valid and provides a real means to address the problem of optimizing module inventory levels with operational availability that before would have been overwhelming and impossible to tackle fully. With the power of today's personal computers, combined with sophisticated simulation programs, simulating the F404 engine module repair process at the afloat Aviation Intermediate Maintenance Depot (AIMD) level is accomplishable. The simulation model is developed from real maintenance and usage data and provides a detailed and accurate representation of the repair process. The results of this thesis can be generalized and applied to a wide family of weapon systems. As military leaders struggle more and more with balancing readiness and limited funds, the metamodel presented in this thesis offers a visible decision-support tool.
