区域公交的多车场车辆调度优化

在运营企业费用最少的基本模型基础上,以乘客等待费用最少为目标函数讨论多车场车辆调度问题,并建立相应模型。基于逆差函数算法对模型求解,设计两种方法进行求解:一种是人工插入空驶车程,求解过程中加入乘客等待时间的限制;另一种是通过由逆差函数为基础设计的PT-Manager仿真软件进行算法优化,对实际案例进行参数标定以及求解。结果表明:该模型逆差函数算法求解过程简单、结果直观,PT-Manager仿真软件能够帮助公交调度人员进行车辆调度及优化,对现有的车辆调度以及多车场的发展有一定的指导意义。

Optimization of Vehicles Dispatching Model for Multiple Depots in Regional Traffic

On the base of the fundamental model whose objective was to minimize the company’s costs,multiple depot dispatching problem was discussed and then the corresponding model was established,in which minimizing passengers’ waiting expense was considered in the objective function.Then deficit function was used to solve the objective function,which can be solved in two different ways: firstly,manual work was used to insert the deadheading trips to restrict the passengers’ waiting time;secondly,PT-manager simulation software which was built on the base of deficit function was introduced to simulate and analyze.In order to make a statistic explore the actual data was introduced.The results proved that the using deficit function to solve the proposed model is simple and accurate.PT-manager simulation software could provide guide and optimization for bus dispatching staff,which also could provide referential significance to the current bus dispatching and the development of multiple depot dispatching.
