| 摘 要： | 为指导城市物流设施的规划和建设,针对城市物流系统是个多层次结构、不同层次的节点间存在物流量流动、不同层次节点的选址互为影响的特点,提出城市双层配送网络布局模型.在考虑大型物流节点向小型物流节点的中转配送关系以及大型节点的规模仓储成本的基础上,对物流园区(Logistics Park,LP)层节点和配送中心(Distribution Center, DC)层节点进行联合布局.采用求解边际成本对模型分段线性化的启发式算法,对非线性模型进行求解.以某市为例对模型进行验证,结果表明该模型具有良好的适用性.

| Abstract: | In order to provide guidance for planning and construction of the city logistics facilities, in view of the fact that city logistics system is a multilayer structure and there is the goods flow and location influence between upper and lower layer nodes, a location model for city double hierarchy distribution nodes is proposed. In this model, the sites of Logistics Parks (LP) and Distribution Centers (DC) are located jointly considering expressed transferring distribution relations from upper nodes to lower nodes and scale cost of the large nodes. A piecewise linearization heuristic algorithm under computing the marginal cost is applied to solve the nonlinear model. An application checking calculation about a city for this model shows that the model has a good serviceability. |
