摘要
以上海市轨道交通运营网络和规划网络为例,基于复杂系统理论首先分析其网络特征值,然后研究网络受到随机攻击和蓄意攻击时的可靠性,发现规划网络能够更加有效地抵御攻击,但是整个上海轨道交通网络面对蓄意攻击时表现出脆弱性,应加强保护关键节点和关键线路。最后对比两个网络节点失效和线路失效后的情况,结果表明:站点和线路的重要性随着网络的完善而不断改变,关键节点逐步转变为郊区乘客进入中心城区的换乘车站,而关键线路则由一二四号线逐步转变为连接浦东新区的线路。
Taken shanghai currently operating network and plan network as an example and based on the theory of complex systems, this paper first analyzes network characteristic values. The reliability of the network is then ana- lyzed under a random accident and an intentional attack, finding that plan network can resist attacks more efficient- ly. But the Shanghai rail transit network shows great vulnerability in the face of deliberate attacks, it is supposed to strengthen the protection of key nodes and lines. Finally this paper compares important nodes failure and line failure of the two networks, the results show that the importance of nodes and lines changes with the network improvement ; key nodes change into the transfer stations that suburban passengers go through when go to city center; key lines transform from Linel ,2,4 into lines connecting Pudong new area.
