다차원 선호도 분석법을 활용한 공군 주요 항공기의 기종별 특성

The Republic of Korea Air Force (ROKAF) is continuously improving operational systems for spare parts because their effective and efficient management of spare parts is closely related to ROKAF``s operational readiness. Spare parts for the ROKAF account for the largest portion of the Republic of Korea Armed Forces`` budget of spare parts. The purpose of this study is to diagnose effectiveness of current operational systems for spare parts so as to improve efficiency and maximize operational capability. This study uses Multidimensional analysis of Preference Data (MDPREF) to examine features of aircrafts operated by ROKAF based on indexes used in logistics of ROKAF. The indexes include available rate, cannibalization, supply action rate, supply support rate, customer waiting time, demand accommodation, equipment maintenance budget, zero balance, procurement lead time, requisition objective, and G-NORS. In particular, this study shows that maintaining the available rate for latest aircraft is more important than economic feasibility. Thus, procurement of spare parts should be prioritized on latest aircraft. The results from this study can be applied to inventory management policy for spare parts and should be connected to inventory practices for a more efficient implementation.
