摘　　要：为了建模并分析铁路快速货物运输网络(REFTN)性能,提出L空间下铁路快速货运无向无权复杂网络(UUCN)建模方法、节点重要度综合评价指标和基于综合重要度节点失效的网络鲁棒性分析方法;依据中国铁路快速货运列车时刻表和车站间日均交互车流等数据,建立UUCN-REFTN模型,并分析其拓扑特性和静态鲁棒性。结果表明:现阶段我国REFTN具有典型的小世界、无标度和同类匹配特性;节点的随机失效对网络的鲁棒性影响较小,节点遭受最大综合重要度破坏比遭受最大度数破坏和遭受最大介数破坏使得网络变得更脆弱,当遭受最大综合重要度破坏的车站占比达到38%时,网络完全崩溃。In order to model and analyze performance of REFTN,method of modeling undirected and unweighted complex network of REFTN(UUCN-REFTN)in L-space,comprehensive importance evaluation index of nodes and network robustness analysis method considering node failure based on comprehensive importance indexes were proposed.Based on timetable and wagon-flow data,UUCN-REFTN was established and its topological characteristics and static robustness were analyzed.The results show that REFTN has typical small-world,scale-free and congeneric matching characteristics at present in China.Random failure of nodes has less impact on network robustness generally,and largest-comprehensive-importance attack makes it more vulnerable than largest-degree attack and largest-betweenness attack.When proportion of stations under largest-degree attack reaches 38%,the network will completely collapse.
