【摘要】：通过构建危险品运输超网络模型,分析了网络之间的相互作用和影响,继而建立了危险品运输网络模型生成方式;通过引入危险品运输网络"最短路径"、"平均最小风险路径距离"和"网络最大连通子图"概念,提出了"网络风险效率"和"最大连通度"抗毁性测度模型;根据网络流量特性,构建了危险品运输网络介数模型。以危险品运输网络为例进行仿真,仿真结果表明:危险品运输网络抗毁性表现为对随机攻击的鲁棒性和蓄意攻击的脆弱性,抗毁性更接近于无标度网络;其抗毁性是由少数节点和边维系的,且网络对节点攻击的抗毁性低于对边攻击的;网络最大连通度性能优于网络风险效率,适当增加系统冗余性可提高网络抗毁性。
[Abstract]:By constructing the hypernetwork model of dangerous goods transportation, the interaction and influence between the networks are analyzed, and then the generation mode of the dangerous goods transportation network model is established. By introducing the concepts of "shortest path", "average minimum risk path distance" and "network most Dalian pass subgraph", the invulnerability measurement models of "network risk efficiency" and "maximum Dalian pass degree" are put forward. According to the characteristics of network traffic, the network medium model of dangerous goods transportation is constructed. Taking the dangerous goods transportation network as an example, the simulation results show that the survivability of the dangerous goods transportation network is the robustness to random attack and the vulnerability to intentional attack, and the invulnerability of the dangerous goods transportation network is closer to that of scale-free network. The invulnerability of the network is maintained by a few nodes and edges, and the survivability of the network to the node attack is lower than that of the side attack. The most Dalian penetration performance of the network is better than that of the network risk efficiency, and the network invulnerability can be improved by properly increasing the system redundancy.
