摘要
为解决断面客流空间分布不均衡程度较高的城市轨道交通线路上不同交路区段中列车相互制约、不能以最小列车运行图周期周转的问题,基于"运行图周期分析法"理论来确定不同交路区段中列车运行图周期,将其作为计算运用车数和固定运营成本的依据。以列车开行数量、行车间隔以及编组数为决策变量,以乘客在站候车时间成本、车辆固定运营成本以及虚糜运能成本最小化为目标函数,建立多目标非线性混合整数优化模型。通过将各项成本换算为总成本,原模型简化为单目标优化模型并进行实例分析。结果表明,列车大小交路开行方案相较常规交路开行方案,总成本有明显下降,从而验证了模型的可行性与有效性。
On the urban rail transit with imbalanced distribution of cross section passenger flow,the operations of trains on different routes are incompatible and the trains cannot run at the minimum cycle of the train working diagram.To solve this problem,the train working diagram cycle analysis method is applied to define the train working diagram cycle,which is used as the basis of fleet and fixed operation cost calculation.A multi-objective nonlinear mixed integer programming model is established by selecting the passenger in-station waiting time cost,fleet fixed operation cost and capacity waste cost minimization as the objective functions.Different costs are converted into a total cost and the original model is optimized as a single-objective model,which is then verified with actual cases.The results show that,compared with the classic operation plan,the long and short routing operation plan helps reduce the total cost.The model is proved to be feasible and valid.
