초록

장기간 사용하지 않는 군수 수리부속품으로 인한 국방예산의 낭비가 발생하는 반면에 야전부대에서 재고부족으로 필요한 수리부속이 적시에 보급되지 못해 문제가 되고 있다. 초과재고의 발생 원인은 민간분야처럼 다단계 군수지원체계에서 하위공급망에서 상위공급망으로 갈수록 수요정보왜곡에 의한 채찍효과 때문인 것으로 알려져 있다. 하지만 군수정보체계 개선 이후 채찍효과의 가장 직접적인 원인이었던 사용자부대의 수요정보를 군수사가 공유할 수 있음에도 불구하고 초과재고 현상이 지속적으로 발생하고 있고 기존의 연구만으로 재고부족 현상은 설명할 수 없다. 또한 기존의 연구는 주로 적정 재고량을 예측하는데 중점을 두었으며 예산과정의 특성(예산주기, 조달기간, 인가저장 유무)은 크게 관심을 두지 않았다. 따라서 본 연구의 목적은 시스템 다이내믹스 이론과 시뮬레이션 기법을 통해 군수지원체계에서 예산과정에 의해 발생하는 정보왜곡과 이로 인한 초과재고 및 재고부족 현상을 분석하는 것이다.

Unused spare parts of military equipments which have been kept in the warehouse for a long term have been recognized as wasting of defense budget which also decreased people's confidence in the field of national defence. It is known that overstock is caused by information distortion and bullwhip effect from downstream to upstream in the logistic support as is like business cases. After upgrading the logistic information system, it is possible for Army Logistics Command(ALC) to know demand information of end-user which is the key factor to reduce bullwhip effect. However, inventory is still overstocked and stock-out at the same time. Previous studies have not accounted for these phenomenons and have mainly focused on forecasting inventory level instead of budgetary process(budget period, PROLT, ASL/N-ASL). Thus, this study focuses on the information distortion, overstock and stock-out which caused by budgetary process in the logistic support with system dynamics and simulation.
