계획 생산 시설과 주문 생산 시설을 갖는 일렬 생산 시스템에서 재고 할당 및 수요 통제 전략의 통합적 구현 = Coordination of inventory rationing and admission control in a two-stage make-to-stock and make-to-order tandem system

국문 초록 (Abstract)

본 논문은 계획 생산 시설과 주문 생산 시설로 이루어진 일렬 생산 시스템을 다루고 있다. 계획 생산 시설은 주문 생산시설이 필요로 하는 부품을 생산하며, 또한 부품 현물 시장이 존재하여 기업은 의사 결정을 통해 부품을 판매한다. 본 논문은 기업의 수익을 최대화할 수 있는 주문 수요 통제와 부품 재고 할당 전략을 통합적으로 구현하는 문제를 다루고 있다. 본 논문에서는 이 문제를 마코프 의사 결정 문제로 접근하여 최적 전략의 함수적 특성을 분석하고 이를 토대로 두 가지 휴리스틱을 제안하였다. 본 논문은 최적 전략과 휴리스틱의 수행도를 비교하는 수치 실험을 수행하였고 확률 프로세스의 변동성이 주문 수요 통제 전략과 재고 할당 전략에 미치는 영향을 시뮬레이션을 통해 분석하였다.

다국어 초록 (Multilingual Abstract)

This paper considers a manufacturer with make-to-stock and make-to-order production facilities. The MTS facility produces a single type of component and provides components for the MTO facility. The MTS facility also faces demands from the market with the option of to accept or reject each incoming demand. We examine the structure of the optimal inventory rationing and admission control policy so as to maximize the manufacturer's profit, and present two types of heuristics. We implement a numerical experiment to compare the performance of the optimal and heuristic policies, and a simulation study to examine the impact of the stochastic process variability on the inventory rationing and admission control.
