摘要:

煤炭运输网络是包括铁路、公路、水路运输等多种方式的复杂网络,处于动态、开放的环境中并受各种不确定因素影响.为了更好地测度煤炭运输网络抵御破坏的能力,提高煤炭运输网络的结构鲁棒性,本文基于煤炭运输网络特性,在分析影响结构鲁棒性的内部和外部因素的基础上,定义了煤炭运输网络的结构鲁棒性,建立了煤炭运输网络结构鲁棒性评价指标体系,并以山西煤炭运输网络为算例进行仿真分析.结果表明,煤炭运输网络对于边随机破坏和按照度攻击,表现出较好的里程可达鲁棒性和效能鲁棒性;随机攻击节点和按照度攻击节点时,网络的结构熵鲁棒性变化不明显;对网络进行攻击的同时以一定的概率修复网络,网络呈现出较好的恢复鲁棒性.

Abstract:

Coal transportation network is a complex network including railway, highway, waterway and other transportation modes. It is in the dynamic and open environment and vulnerable to the uncertain factors. To effectively measure the ability of coal transportation network to resist destruction, and improve the structural robustness of coal transportation network, this paper defines the structural robustness of coal transportation network based on the characteristics of coal transportation network and analyzing the internal and external factors influencing structural robustness. It also establishes the evaluation index system of structural robustness of the coal transport network and takes Shanxi coal transportation network as an example for simulation analysis. The results indicate that the coal transportation network shows better robustness of mileage up and performance robustness for stochastic damage to the edge and attack in accordance with the degree. When the attacking nodes are random distributed or the nodes are attacked in accordance with the degrees, the changes of robustness in network structure entropy are not apparent. When attacking the network with repairing network with a certain probability at the same time, the network shows a good recovery robustness.

Key words: integrated transportation, structural robustness, robustness evaluation, coal transportation network, recovery robustness, performance robustness, evaluation index
