英文摘要：
This paper studies a supply chain configuration (SCC) problem for a green product family in consideration of guaranteed service time and emission constraints. Several alternative options can be employed to implement the functions of each stage and safety inventory is adopted to satisfy stochastic demands. An SCC model is formulated to optimize the service time and option selection decisions to minimize the overall cost of the supply chain. The structural properties of the model are addressed and the problem is decomposed into two subproblems, namely, the service time decision problem and option selection problem. For the service time decision problem, the structural properties of the supply chain network is carefully studied, based on which a spanning tree-based algorithm (STA) is presented to solve the problem optimally. For the option selection problem that is proven to be NP-hard, a particle swarm optimization algorithm (PSO) is adopted to efficiently solve the problem. Consequently, a hybrid algorithm (STA+PSO) is developed to solve the SCC model. The numerical results show that the hybrid algorithm can efficiently and effectively solve the SCC model. The emission constraints on green products have significant effects on the supply chain cost and the emissions of the products; while the guaranteed service time also remarkably influences the supply chain configuration.

本研究从供应链角度研究绿色产品生产运作管理，在服务时间和碳排放的双重约束下，优化供应链各环节的生产运作方式，对供应链进行优化配置。供应链由多个节点组成，而且不同的节点都可以选择不同的运作模式进行生产，不同的模式意味着不同的生产产品、碳排放和服务时间。该研究构建了一个考虑服务时间和碳排放双重约束的供应链配置模型，并开发了一个混合算法对该模型进行了求解。
该研究研究了多个节点和多个企业合作情况下，绿色产品供应链的协作和优化配置问题，为供应链企业提供了应对互联网情况下的配货时间约定和环境管制的决策方法，为供应链各环节的运作管理提供了决策支持，同时也为政府如何制定针对供应链的环境支持提供了决策依据。
