公交车调度方案设计

1、公交车调度方案设计 公交车调度优化模型设计  摘要  本文所要解决的是公交车调度的问题，首先根据所具备的数据资料以及要求，考虑到乘客等车时间的限制，建立了1个线性模型，使所求得的调度方案更符合题目要求。然后，从乘客与公交公司的利益出发，设定1系列的指标，利用模糊评价的方法来对调度方案进行综合分析与评价。其次，把这个调度问题抽象成为1个数学规划模型，通过到本城市公交车站实地调查访问，得到运营数据的采集方法。最后，利用计算机模拟的方法对模型进行了检验，同时对模型的优缺点进行了分析，并提出改进方向。在模型1中，对问题1建立了求最大客容量、车次数、发车时间间隔等模型，运用

2、决策方法给出了各时段最大客容量数，再与车辆最大客容量比较，得出载完该时组乘客的最少车次462次，从便于操作和发车密度考虑，给出了整分发车时刻表和需要的最少车辆数61辆。模型2建立模糊分析模型，结合层次分析求得模型1带给公司和乘客双方日满意度为（0.941，0.811）；根据双方满意度范围和程度，找出同时到达双方最优满意度（0.8807，0.8807），且此时结果为474次50辆；从日共需车辆最少考虑，结果为484次45辆。对问题2，交待了综合效益目标模型及线性规划法求解。对于问题3，借助了查阅资料和搜集数据。关键词  公交调度；层次分析；满意度。abstract this text
