기존 연구에서 서비스 시간 분포를 포아송 분포나 지수분포를 이용하여 전개하던 재고시스템에서 일반서비스 시간분포를 갖는 수리가능 재고 시스템으로 확장한 연구임.
This paper presents an efficient method for the problem of determining the spare inventory level of a multi-echelon repairable-item inventory system. We consider the system with two levels of inventory, two levels of service and with a general service time distribution. We propose an algorithm that determines the spare inventory level to satisfy the minimum fill rate with the minimum cost. Experimental results show that the algorithm is accurate and efficient.
