| Summary: | 碩士 === 國防大學 === 資源管理及決策研究所 === 105 === The principle of our military strategy follows the concept of “Strong Defense Posture, Effective Deterrence” and strengthens the capability of air-ground operations, Special Forces, logistic support, etc. Since the Army Aviation and Special Forces Command’s helicopters have high mobility and can work with the air-ground operations; therefore, it could implement a variety of tasks. As a result, the Ministry of National Defense uses the helicopter troops as a part of restructuring of the armed forces.
This research focus on the type of Army Aviation helicopters, as this type of helicopters has been serving for more than twenty years accumulating operation hours. The Army Aviation units are facing the problems of spare parts shortage and delivery delay. Consequently, the spare parts inventory is hard to meet the maintenance requirement, which let the aircraft be grounded or even be put into storage. We apply system dynamics to find out the cause-effect relation of critical variables and build a system dynamic analysis model. As a result, this model can be used to simulate different policies, and see the differences of the availability, the number of storage, the spare parts demand and supply, the man-hour demand and the delay time of aircraft removal from storage. The policies, include budget satisfaction rate, safety stock, one for one exchange rate, domestic repair ratio, and storage period. Relevant policy recommendations will also be discussed in this paper.
