초록
It is difficult to determine an optimal inventory level of aircraft engine and modules to achieve the ta rget operational availability since F100-PW-200 & 229 engines of the F-16 & KF-16 aircraft are consisted of 5 modules with different failure rates and costs. This study presents a decision model, combining an integer programming problem and a regression metamodel. Data for the metamodel was attained from results of a simulation model, that represents operational and repair process of F-16 and KF-16. The objective function of an integer programming problem is maximizing the operational availability, rep resenting pessimistic circumstances. Finally, an integer programming problem with a metamodel can make an optimal decision of the inventory level.

Finally, an integer programming problem with a metamodel can make an optimal decision of the inventory level.
