시스템 다이내믹스 모형을 통한 공급능력 확장과 반품정책에 대한 연구 = A Study on the Capacity Augmentation and Return Policy in a Supply Chain - Applying a System Dynamics Model

다국어 초록 (Multilingual Abstract)

The purpose of this study is to analyze the effect of the use of return policy on the supplier`s decision on the capacity augmentation under the two-echelon supply chain considering the constraints of supply capacity. Specifically, this study, based on the system dynamics model, aims to compare the results of performances of the supply chain with a return policy with that of the supply chain without a return policy. We consider the total cost, the fill rate as supply chain performance and capacity gap and extra capacity as suitability of capacity augmentation. The simulation results show that the use of return policy significantly affect the supplier`s capacity augmentation. This result implicates that the return policy helps timely expansion of supplier`s capacity, so it can be used as a strategic tool for assisting the balance between supply and demand in the supply chain.
