乌鲁木齐地铁1号线列车开行方案研究

Study on train operation plan of Urumqi Metro Line 1

根据乌鲁木齐地铁1号线路特点及初期预测的客流分布特征,从乘客出行成本与运营成本两个方面考虑,以列车行车间隔与满载率为约束条件,建立了非线性双目标整数规划模型。采用线性加权法对目标函数优化并进行了求解算法的设计。结合初期预测客流对乌鲁木齐地铁1号线进行了开行方案的求解,得出的列车开行方案明显优于现行方案。

Based on the characteristics of Urumqi Metro Line 1 and the characteristics of passenger flow distribution predicted in the initial stage,the nonlinear two-objective integer programming model is established from the perspectives of passenger travel cost and operation cost,with train interval and full load rate as constraints.The linear weighting method is used to optimize the objective function and the algorithm is designed.Based on the preliminary passenger flow forecast,the running plan of Urumqi Metro Line 1 is solved,and the train running plan is obviously better than the current one.
