城市物流基地选址问题研究

本文将物流基地纳入城市交通网络中，以体现交通状况对物流基地选址的影响。在进行选址时，以运输费用和基地的投资、管理费用总和最小为规划者的主要目标，建立目标函数。选址的上层模型体现了运输费用和基地投资费用、管理费用最小的原则，下层模型体现了入选点的不同对交通流量分配的影响，下层模型是求解上层模型的基础。

The Study of Urban Logistic Terminal Location

This paper brought the urban logistic terminal into the urban traffic network to embody the effects the traffic status given to the logistic terminal location. In the process of location, this paper put forward the model on the target of minimum summation of terminal investment, transportation and management cost. The upper-level model embodied the principle of minimum summation of terminal investment, transportation and management cost. The lower-level model embodied the effects on traffic flux assignment from different candidate-location. The lower-level model is the base of solving the upper-level model.
