基于GIS的多粒度复杂网络模型

为提高城市路网失效传播分析和可靠性分析的准确性,研究了路网发生故障的3种失效形式.在此基础上,基于复杂网络理论,提出了一种多粒度复杂网络模型；通过构建粒度空间,将城市交通广义路网表达为多粒度复杂路网.为检验模型的有效性,以成都市区路网为例,建立了道路的多粒度复杂网络模型；基于该网络结构,进行了路网失效传播分析以及分别针对随机攻击和蓄意攻击的路网可靠性分析.研究结果表明,城市道路多粒度复杂网络能更准确地进行路网失效传播分析和可靠性分析,为进一步研究城市交通网络故障的动态演化提供了有利条件.

Multi-granularity Complex Network Model Based on GIS

For the purpose of enhancing the accuracy of the failure spreading and reliability analyses of an urban road network,three kinds of road failure were studied.Based on this,a multi-granularity complex network model was proposed based on the complex network theory,and a generalized network of urban transit was expressed as a multi-granularity road complex network by building granularity space.Experiments were carried out to validate the model by building the multi-granularity road complex network of Chengdu City,and then the failure spreading analysis and the reliability analysis towards random failure and malice failure were conducted.The results show that the multi-granularity complex network model is efficient to the failure spreading and reliability analyses of urban road networks to provide the advantage for the further study of fault dynamic inversion for urban road networks.
