碩士 === 國立東華大學 === 運籌管理研究所 === 100 === Closed-loop supply chain is a series of activitiesbetween forward and reverse logistics. However, uncertainty issues widely occur in the network such as the demand of the remanufacturing products obtained from the consumers, the amount of the recycled goods supplied from the consumers, and others.In order to attain the saving of the materials and the improvement of the reuse value, integrate forward and reverse logistics must be efficiently. Thus, the control of uncertain parameters is extremely importantin supply chain network. This study conducts a supply chain network location model under uncertainty. It is important to allocate the facilities with the extremely expensive sunk cost which it can not relocate in a short period under uncertainty in order to maximize the business effect. We use a robust optimization approach to solve uncertaintyfactors of the model. Numerical results also show the effect of the uncertainty in the supply chain network and provide the guide of facility location.
