为提高客运交通系统的运行效率，分析不同类型客运需求与各等级枢纽间的关系，考虑不同层次枢纽服务能力的约束，构建了基于层级选址模型的区域客运枢纽分层布局优化模型，使用CPLEX优化软件求解，最后设计算例验证了模型和算法的有效性。结果表明，与不分层的中位模型相比，分层模型能得到可达性更高的布局方案，考虑最大、最小服务能力约束后可达性有所下降，但更符合实际。面对客运需求的增长，枢纽规划部门应适当进行枢纽扩能和布局优化调整。

To improve the efficiency of the passenger transport system, a model for regional passenger hub layout is proposed. The relationship between different passenger hub and passenger transport demand is analyzed. A hierarchical model with capacity constraints is built and solved by CPLEX. Numerical example is given to validate the model. The results show that hierarchical model is superior to non hierarchical median model for accessibility. In addition, the minimum and maximum capacity constraints lead to accessibility decline yet make the model more realistic. Hub planning department should expand the capacity of hubs and adjust hub layout in the face of the passenger transport demand increase.
