宏观层次的区域轴-辐式快运网络枢纽节点城市的布局是一个复杂的多指标综合评价问题。文章首先阐述了主成分分析法(PCA)的基本原理及实际操作步骤,然后结合某省实际,在分析影响快运网络枢纽节点城市布局的经济因素基础上,利用主成分分析法建立了评价模型,并据此用spss软件计算出各节点的重要度来进行枢纽节点的布局,计算结果证明了该方法的有效性。
Macro-level Regional Axis-Sporadic Express Hub Network The layout of a city is a complex multi-index comprehensive evaluation problem. In this paper, the basic principles and practical steps of PCA are first described. Then, based on the analysis of the economic factors that affect the urban layout of express hub nodes, this paper establishes the evaluation model by using principal component analysis (PCA) Based on this, the importance of each node is calculated by spss software to make the layout of pivot nodes. The calculation results prove the effectiveness of the method.
