| Summary: | 碩士 === 國立虎尾科技大學 === 工業工程與管理研究所 === 102 === In this paper, we develop the closed-loop sustainable green supply chain network design related problems that possess uncertainty, the two-stage stochastic programming method was applied to construct a mathematical planning model. Considering logistics flows, leasing reverse logistics site selection, capacity expansion and technology investments of existing and potential facilities, and the uncertainty occurred in customer demand and return quantity. The concept of environmental cost was incorporated, environmental taxes were levied against carbon emissions, the total costs are divided into economic costs and environmental costs.
Moreover, the feasibility of the two-stage stochastic programming method was verified then compared with the model of certainty. Findings show that the sustainable supply chain design results in consideration to uncertainties in demand and recycled quantity possessed better robustness. In terms of reverse logistics planning, returned products are handled in two ways, recyclables and acquisition. The effect of changing recycling rates and acquisition rates on net profit was discussed through parameter analysis.
