| 摘 要： | 以铁路货运网为基础,构建了铁路地理网和铁路运输网,运用复杂网络理论分析编组站的布局特征,研究得出了编组站的度、介数、脆弱性、出入度与出入强度、强度相关性等网络指标.基于铁路地理网的统计结果显示,我国编组站的平均度为4.36,介数与度是正相关的,丰台西、山海关、向塘西等编组站的脆弱性较为突出.基于铁路运输网的统计结果显示,编组站的平均入度为11.3,平均入强度为3 331.7,平均出度为11.2,平均出强度为3 478.9,入强度与入度、出强度与出度均呈现正相关趋势.编组站强度相关性研究显示铁路运输网属于非同类混合网络,出入强度较高的编组站倾向于与其他出入强度较低的节点连接.

| Abstract: | This paper constructs railway geographic network and railway transport network based on railway freight network,uses complex network theory to analyze the layout properties of marshalling yard,studies the marshalling yards degree,betweenness,vulnerability,in-degree,out-degree,in-strength,out-strength,neighbor in-strength,and neighbor out-strength.Based on railway geographic network,the average degree of marshalling yard is 4.36,betweenness and degree are positively correlated,the vulnerability of Fengtaixi,... |
