摘　　要：我国快递需求的快速增长和高速铁路规模的发展对高速铁路网络优化、运力合理配置及枢纽节点布局等持续经济运营问题提出了发展要求,也对运输组织和网络运行等提出了规模化的高要求,基于高速铁路客运运力复合利用视角,借助p-中位模型,以最大二次中转的成本最小化函数构建了我国高速铁路快运网络枢纽节点城市的选址模型,并使用禁忌搜索算法求解和利用矩阵表示法合理分配货流量。考虑我国实际高速铁路网络城市分布及城市内站点分布,将高速铁路与枢纽节点城市内中转车辆两种运输方式相结合,以2019年实际的高速铁路旅客列车运行时刻表为实例计算了枢纽站点、城市的枢纽运输成本,形成了高速铁路快运网络节点城市的枢纽成本位序和集散点集。In this paper,from the perspective of the compound utilization of high-speed railway passenger transport capacity,with the help of the p-median model,we constructed the site selection model of the hub cities in the high-speed railway express network of China with cost minimization as the objective under the two-transfers-at-most constraint,used the tabu search algorithm to solve the model,and reasonably arranged the cargo flow distribution via matrix representation.Next,considering the distribution of the cities on the actual highspeed railway network of China and the distribution of high-speed railway stations in these cities,we combined the transportation modes of the high-speed train and the transit vehicles in the hub cities,used the actual high-speed railway passenger train timetable in 2019 as the example to calculate the transportation cost of the hub stations and the cities,and formed the cost sequence and distribution point collection of the hub cities in the high-speed railway express network.
