中文摘要：

为了合理设计制造／再制造混合系统中的集成物流网络结构，综合考虑网络中正向物流和逆向物流的设施集成与运输整舍，以及产品需求量和废旧产品回收量的随机性，提出了一种制造／再制造集成物流网络优化设计的两阶段补偿随机规划模型，用以确定网络中各种设施的数量及其位置，并在由此构成的各条物流路径上合理分配物流量，目标是使计划期内的净成本最小。算例验证了随机规划模型的有效性。

英文摘要：

The problem of designing an appropriate integrated logistics network structure for a hybrid manufacturing/remanufacturing system was investigated. Considering the integration of facilities and combined transportation of forward and reverse logistics in the network as well as the randomicity of the demanded quantities of products and the returned quantities of used products, a two--stage stochastic expected model with recourse was developed for designing such a network. Accordingly, the number of various facilities, their locations and the reasonable allocation of the corresponding goods flows within the network can be decided upon. The objective is to minimize the net cost over the planning horizon. Finally, the validity of the model was illustrated by a numerical example.
