| 摘 要： | 构建了铁路物流中心规模设计优化的双层规划模型.上层规划考虑了铁路运输成本、公路运输成本及建设成本,使系统总成本最小;下层规划使用变分不等式模型描述用户选择铁路物流中心的均衡态.采用EDO算法进行求解.算例验证了模型及算法的可行性与有效性.

| Abstract: | The bi-level programming model ted. The railway transportation cost, high in the upper level to minimize the system level to describe the railway logistics cente is applied to solve the model. The feasibili trated with a numerical example. of size determination of railway logistics centers is construc- way transportation cost and construction cost are considered total cost. Variational inequality is proposed in the lower rs equilibrium choice behavior of customers. EDO algorithm ty and effectiveness of the model and its algorithm are illus- |
