초록
본 논문은 고객으로부터 주문을 받아 제품을 생산하는 제조 기업을 다루고 있다. 주문 생산에 필요한 부품은 공급업체로부터 조달받으며, 주문인도기간은 Erlang분포를 따른다. 기업은 내부로부터의 부품 수요뿐만 아니라 부품 시장으로부터의 수요도 충족시켜야 한다. 따라서 제조 기업은 주문 제품 판매와 부품 판매라는 복수의 수익원을 갖게 되는데, 이로 인해 부품 재고의 배급 문제에 직면하게 된다. 본 논문은 주문인도기간 변동성이 부품 보충 정책과 주문 및 부품 수요 통제 전략에 미치는 영향을 분석하였다. 또한, 본 논문에서는 수치 실험을 통해 주문인도기간의 변동성이 달라질 때 기업의 수익과 주문량에 미치는 파급 효과를 모형의 모수 값들 관점에서 분석하였다.
Abstract
This paper considers a make-to-order manufacturing company. Components required for the MTO production are acquired from the supplier whose lead time process follows an Erlang distribution. In addition to the internal demand from the MTO production, the firm faces demands from the component market, which raises the issue of inventory rationing. The firm has two types of revenue streams; processing MTO orders and selling components. We examine how the lead time variability can affect the component replenishment, MTO demand control, and component inventory rationing. We also investigate the impact of lead time variability on the firm's profit. To this end, we implement a numerical experiment which studies how the optimal average profit and optimal order quantity are changed by the lead time variability.
