高科技軍事裝備為現代戰場決勝之關鍵因素，對於空軍而言，戰機乃是最重要的軍事資產。為了確保戰機妥善可用，完善的維修系統是重要的關鍵因素。有鑑於此，如何解決確保戰機妥善之複雜問題乃是機場指揮官最重要的課題之一。本研究運用系統動態學之觀點建立一套戰機維修系統模型(MAMS)，不僅可藉由本研究所建立之系統行為模擬來評估現行戰機維修制度的適用性、建立器材安全存量的參考數據、規劃維修人力的有效基準、以及訂定理想預算的支用水準等等，並可經由大量系統參數的模擬測試，發掘影響戰機可用度之關鍵因素。 模擬結果發現，本研究所建立的模型最終可達動態平衡，且符合現行戰機維修制度的行為。透過政策參數之改變，可以預測戰機可用度是否滿足作戰任務需求，此外，藉由敏感性分析測試，獲得影響戰機故障率的決定性臨界值，藉以預測武器系統維修運作之發展，提供後勤整備規劃的依據。本研究所建立的模型可正確、有效地探索動態系統行為模式，作為專案決策者之決策支援工具。 Advanced technology military equipment is a key factor to achieve victory in a war. For the Air Force, military aircraft is one of the most important assets. In order to ensure military aircraft mission readiness, developing a perfect maintenance system is crucial. Hence, how to deal with the complicated problems affecting mission readiness is one of the most challenging issues. This research applies the System Dynamics to establish a Military Aircraft Maintenance System (MAMS). MAMS system behavior simulation can be used to assess the applicability of current military aircraft maintenance systems, establish reference parameters of safe material stock levels, preplan an effective foundation of maintenance manpower, and obtain an adequate budget level. MAMS’ vast systems parameter simulation capabilities can aid in determining key factors which influence the military aircraft availability. The model established by this research achieved dynamic balance by utilizing system simulation and considering current military aircraft maintenance systems. By adjusting the decision-making parameters, the system can forecast if military aircraft availability meets the operational mission requirements. In addition, sensitivity analysis can be used to obtain the decisive threshold value influencing malfunction rate, and also forecast the development of military aircraft essential for logistics planning. Hence, the model proposed by this research is capable of exploring dynamic system behavior accurately and effectively, making it a viable decision making support tool in project management.
