公交车调度优化模型

The Optimizing Model on the Dispatch of Buses

研究了随着时间和空间上客流不均衡性的变化 ,车辆应如何调度的问题 ,建立了多目标规划的模型。实现了“有早出 ,有晚出” ,车辆有多有少的调度计划。在保证一定效益和顾客满意的情况下 ,使在岗车辆的总运行时间最短。所有的计算都在计算机上实现 ,得出了调度时刻表 ,最少的车辆数为 4 2 ,顾客与公交公司的满意程度比为 :0 .6 8∶0 .4 6 .

This passage discusses the problem of how to determine the timetable of the buses on a certain route under the condition of known statistical data of passenger flow at various stops during every time period. Under normal conditions, bus companies arrange for the vehicle dispatching timetable on the basis of investigated data with the succession method during work days to make a group of buses file in and out during operation period while we have mainly done the research on the uneven variation of the passenger flow in time and space, the research on the laws of how to dispatch buses and we have established a target planning model which has realized the dispatching plan of some early and some late and when there are more, when there are fewer. Under the circumstances of ensuring certain benefits and the satisfaction of passengers, overall operating time of the buses in operation has been made the shortest, the dispatching timetable has been got, while the number for the least buses is 42 and the ratio of satisfaction between passengers and bus companies is 0.68:0.46.
