摘要
构建考虑信息精度和广度的网络级联失效模型,引入节点、连边容量参数来控制节点、连边冗余能力,对失效节点和过载节点采用基于连边冗余能力的不同负载分配策略进行负载分配,以此探究航空运输网络在不同攻击信息攻击下级联失效特性。构建航空运输网络并进行仿真实验,以此来研究航空运输网络在面对不同攻击信息时所表现出的抗毁性能力。结果表明:攻击者不需要完全掌握网络全部信息,所获信息只要超过特定阈值,即可使网络破坏性达到最大,且攻击信息精度比攻击信息广度对网络抗毁性影响更大。
This paper builds a network cascading failure model considering information accuracy and breadth,introduces node and connection side capacity parameters to control node and connection side redundancy,and uses different load distribution strategies based on connection side redundancy for load distribution of failed nodes and overloaded nodes,so as to explore the failure characteristics of air transport networks under different attack information attacks.The air transport network is constructed and simulated to study the invulnerability of the air transport network in the face of different attack information.The results show that the attacker does not need to fully master all the information of the network.As long as the information obtained exceeds a specific threshold,the network destructiveness can be maximized,and the accuracy of attack information has a greater impact on the network invulnerability than the breadth of attack information.
