校园公共自行车站点选址研究——以天津大学北洋园校区为例

Research on Site Selection of Public Bicycle——Taking Beiyang Campus of Tianjin University as an Example

在分析公共自行车布局研究不足的基础上,建立了基于Gis和遗传算法的校园公共自行车站点选址模型。从学生满意度和企业的成本两方面出发,确定了校园公共自行车站点的选址目标及影响因素;利用Gis定量分析可在地图上表现的影响因素,得出候选站点;引入中值模型结合遗传算法,得到最终站点;建立单调度中心无时间窗约束的调度优化模型,结合遗传算法在Matlab上实现。

Based on the lack of analysis of urban public bicycle layout research,a public bicycle site location model based on Gis and genetic algorithm is established.From the aspects of student satisfaction and the cost of the firm,the location selection objective and influencing factors of the campus public bicycle station are determined.The influence of the spatial analysis function of Gis can be used to quantitatively analyze the influencing factors that can be expressed on the map.The best site location can be obtained by using median model combined with genetic algorithm.A scheduling optimization model with no time window constraint in single scheduling center is established,combing with genetic algorithm and Matlab.
