中文摘要: 道路运输网络级联失效指在道路运输网络中少数几个节点或路段发生故障,会通过节点之间或路段之间的连接关系引起其他节点或路段发生故障,发生连锁效应,从而导致道路运输网络出现级联失效。本项目通过构建级联失效模型,确定级联失效影响源,识别脆弱节点或路段,结合北部湾城市群物流道路运输网络特点进行可靠性优化研究,达到提出控制级联失效方法,提高物流道路运输网络可靠性的目的。首先,对北部湾城市群物流道路运输网络现状进行研究;其次,根据城市群道路运输网络相互依赖、关联程度高、内部动力学特征复杂的特点,深入剖析物流道路运输网络级联行为动力学演化过程和规律特征,揭示级联行为生命周期,识别级联过程中的脆弱点和路段;再次,对级联失效影响源进行辨识,确定影响因素并排序;最后,建立级联失效模型,确定模型算法,优化各种影响源下北部湾城市群物流道路运输网络可靠性,识别物流道路运输网络中的脆弱节点和路段、分析潜在瓶颈。

英文摘要: Cascading failures of the transport network means a few nodes or links in the transport network are failures which will transmit other nodes or links when the chain reaction occur, so cascading failures may occur. This project will determine the impact of the cascade source and identify vulnerable nodes or links by constructing cascading failure model. Study the logistics and transport networks' reliability of Beibu Gulf city group to find better ways to control the cascade failure and improve logistics and transport network reliability. Firstly, research the Status of Beibu Gulf city group logistics networks. Secondly, in-depth analysis of the Beibu Gulf city group logistics network cascade behavior based on the transport network of interdependence , a high degree of association , the internal dynamics characteristics of complex features. Thirdly, identify the impact of cascading failure source to determine the factors and sorting. Finally, a cascading failures model and its algorithm will be established under the special conditions to study the various sources effect on the reliability optimization of the transport networks. Then identifying vulnerable transport network nodes and links and analyzing potential bottlenecks.
