摘要
我國軍事戰略循「防衛固守、有效嚇阻」的構想，強化地空整體作戰、特戰與後勤支援等能力，而陸軍航空特戰指揮部的直升機部隊，由於機動性高可配合地空整體作戰，執行多種任務，故國防部將陸航直升機部隊列為兵力整建重點之一。本研究以陸航某型現役直升機為研究對象，由於該型機服役已超過20年，隨著操作時數的累積，故障狀況隨之增加，再加上零附件短缺及延遲交貨等因素，使備份件籌補數量難以滿足維護作業需求，常導致裝備停用與封存情形，進而影響妥善率。本研究運用系統動態學，找出關鍵因素及其互動影響關係，據以建構動態分析模型，並進行政策分析與模擬，探討軍售採購預算滿足率及安全存量政策調整，對於妥善率及封存機之影響趨勢，希望透過研究，提出相對較佳之政策，做為管理者政策制定參考。

Abstract
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 which include budget satisfaction rate and safety stock, and see the differences of the availability and the number of storage. Relevant policy recommendations will also be discussed in this paper.
