| Summary: | 碩士 === 中原大學 === 工業與系統工程研究所 === 105 === The current rise in environmental awareness has resulted in a stricter government regulation on environment protection. Therefore, the trend towards green supply chain has become a common trend. In the manufacture-retailer supply chain, transportation activities produce the largest proportion of carbon emissions. Therefore this research improves the usage level of return vehicle to make supply chain more sustainable. Using the Just in Time (JIT) concept, we propose a high-frequency and low-volume transportation network which enables a quicker response of the supply chain. The system allows goods to arrive just in time, and thus reduce the inventory cost. We design the research for two return vehicle scenarios. In the first scenario, goods are transported from the DC to the retailer and the return vehicle carries the recyclable packaging material from retailers back to the DC. In the second scenario, the goods are delivered in a circular loop from the manufacturer to the DC, thus reducing the inventory. With the above established supply chain network concept, we use ILOG CPLEX12.4 software to derive the minimum carbon emission and minimum total cost green supply chain.
