摘要
机场市域铁路作为连接机场和城市的重要线路,其运营方案的设计对于机场和周边城市的发展至关重要,本文对机场市域铁路列车开行方案进行深入研究,寻找优化方案.首先,对机场市域铁路的功能定位进行研究,通过对比几种常用的交路类型,提出建立一套大小交路结合的开行方案.在此基础之上,以旅客等待时间最小和车辆走行公里数最小为目标函数建立一个多目标混合整数非线性规划数学模型,并用线性加权法求解该模型.最后,结合西安机场至富平市域铁路进行案例分析,使用Python调用Gurobi求解器,得到西安机场至富平市域铁路高峰小时开行14对大交路列车,7对小交路列车,小交路折返站设置在机场站和高陵站的最优列车开行方案.
Abstract
Airport metropolitan railway is an important route connecting the airport and the city,its operational design is crucial for the development of the airport and surrounding cities.In order to address this issue,this paper conducts an in-depth study on the operating plan of the airport metropolitan railway trains to find optimization solutions.Firstly,the functional positioning of the airport metropolitan railway is studied,and a set of operating plans combining large and small routes is proposed by comparing several commonly used route types.Based on this,a multi-objective mixed integer nonlinear programming mathematical model is established with the objective functions of minimizing passenger waiting time and vehicle kilometers traveled,and the model is solved using linear weighting method.Finally,combined with the case analysis of Xi'an Airport to Fuping Metropolitan Railway,Gurobi solver is invoked using Python to obtain the optimal operating plan of 14 pairs of large-route trains and 7 pairs of small-route trains during peak hours for Xi'an Airport to Fuping Metropolitan Railway,with small-route turnaround stations set at the airport station and Gaoling station.
