초록
It is important to maintain on operational availability of aircraft during wartime. The KF-16 fighter, the backboneof the ROKAF (Republic Of Korea Air Force), has a single engine. Therefore, the engine has a critical influence onoperational availability. The purpose of this study is to estimate optimal levels of spare part inventories concerningboth engines and modules. That is provided by linear programming methods utilizing a developed meta-model. Fordrawing out the meta-model, we develop a simulation model which can consider wartime demands. In the previousstudy, 2k factorial design method is used to check the influence of each independent variable. That method requiresrelatively many scenarios because every extreme value combination of independent variables should be checked. However, this study adopts NOLH (Nearly Orthogonal Latin Hypercube) as an experimental design. By adopting NOLH,this study increases not only efficiency but also accuracy. That is proven by comparing the validity of the developedmeta-model on both experimental designs. This study also utilizes the OptQuest simulation tool in ARENA to derivethe optimal level of spare stocks. By comparing the result of OptQuest to that of the developed meta-model, the validityof this study is secured.
