针对开行方案编制模型复杂、求解困难的特点,从制定开行方案求解策略出发,以客运站所在城市为节点,研究快速客运网客运节点的等级划分方法。以节点的定量和定性属性作为聚类分析参数,采用变量聚类选取合适的分类变量,再通过样本聚类将节点进行分类,并以2008年日均旅客发送量前100位的客运节点为例进行分类,结合客运专线规划和既有线的实际运营情况修正聚类分析结果,最后制定基于节点等级的旅客列车开行原则,为开行方案设计奠定基础,降低问题的求解规模和难度。
In view of the complicated programming model and difficult solution, this paper starts from the solution of developing project and takes the city where the terminal is located as a node to study the method of classifying the passenger nodes of express passenger network. Taking the quantitative and qualitative attributes of nodes as clustering analysis parameters, using variable clustering to select the appropriate classification variables, and then classifying the nodes by sample clustering. Taking the top 100 passenger nodes in 2008 as the example, According to the planning of passenger dedicated line and the actual operation of existing line, the result of cluster analysis is revised. Finally, the principle of opening passenger trains based on node level is worked out, which lays the foundation for the design of open plan and reduces the scale and difficulty of solving the problem.
