摘要
为提高城际公交的运营效率,对不同线路的运营车辆进行了跨线调度研究.从系统的角度分析了车辆跨线调度的可行性,构建了各发车场站的逆差函数,通过同城市的不同场站之间及同场站的不同线路之间的跨线调度,最大化削减了城际公交线路运营的车队规模,从而节约了客运企业的运营成本.对城市Y、Z之间的城际公交线路,维持线路正常运营所需的最小车队规模为38辆,而经过跨线调度优化后,仅需32辆,优化了运营车辆数目.本研究可以有效提高运营车辆的利用率,最大程度减少运营成本.
To improve the operational efficiency of inter-city bus lines, cross-line scheduling is studied for operational vehicles belonged to different lines. From the perspective of system, the feasibility of cross-line scheduling is analyzed. Deficit function is constructed for each depot to maximally cut operating fleet size on inter-city bus lines by cross-line scheduling between different depots in the same city and scheduling within the same depot for different lines. Thereby, operating costs of transport enterprise are saved. Intercity bus lines between City Y and Z are cross- line scheduled to optimize the number of operational vehicles.Results show that the minimum fleet size is 38 vehicles keeping the lines operating normally, and only 32 vehicles are required after scheduling optimization. It can effectively improve the utilization of operational vehicles and minimize operating costs.
