초록

본 연구에서는 재생산 기업의 회수 인센티브와 소매점에서의 회수 인센티브를 고려하여 최적 총 주문량과 이 두개의 최적 인센티브에 대한 결정을 연구한다. '회수율은 기업이 제공하는 인센티브와 밀접한 관련이 있다.'는 가정하에 이 회수율을 두 경로로 가는 각각의 함수로 표현하였다. 재고 모델로는 확정적인 EOQ(경제적 주문 수량)모델을 사용하여 기업의 최소 비용함수를 수식으로 표현하였다. 또한 이 모델을 가지고 볼록성(convexity)을 증명하여 기업이 수여하는 최적 인센티브와 소매점이 수여하는 최적 인센티브 그리고 총 주문수량(보충량)을 최적화하였다. 그리고 각각의 매개변수들을 민감도 분석하여 각각의 결정변수의 변화 추이를 살펴보면서 매개변수와의 관계를 알아보았다. 기업과 소매점은 비용을 감소시키기 위해 인센티브를 낮추려 한다. 하지만 이것은 회수량을 감소시켜 새로운 제품 생산량을 증가시킴으로 비용을 증가하게 한다. 이 논문은 국내외 재생산 기업이 이러한 상충관계(Trade off)를 고려하여 최적 인센티브와 최적 주문량을 결정하는데 있어 도움이 될 것으로 기대한다.

In this paper, we develop the cost minimization model to select two incentives and total order quantity with consideration of remanufacture company's return incentive. Return rate is sensitive to the incentive that the manufacture company offers. Using a EOQ(Economic Order Quantity) model of a cost minimization, we show concavities of the model about two incentives and total order quantity respectively. According to the proposed algorithm using the concavities, we find out the optimized incentive prices and total order quantity. Through numerical study, we examine sensitive analysis of the incentive price and order quantity for each parameter when the return rate is sensitive to incentive. Company lessens incentive to reduce total price. However, this makes the total price increase due to a diminution of return quantity. We expect that domestic or overseas remanufacture businesses are able to decide optimal incentive and total order quantity by this research.
