为了研究灾害在基础设施网络间的传播情况,提出一种基于复杂网络的基础设施网络关联响应的计算方法.给出基础设施系统的网络模型描述规则,并以华中地区某城市的供水和供电系统为例建立了基础设施系统关联响应模型.给出了网络关联响应因子的定义,研究了城市供水网络和供电网络在随机失效和蓄意攻击下关联因子的变化,结果表明:攻击发生时,关联响应因子先增加后减少,随机攻击时的关联因子比蓄意攻击时要大.
In order to study the transmission of disasters between infrastructure networks, this paper proposes a method to calculate the association response of infrastructure networks based on complex networks, and gives the network model description rules of infrastructure systems. Based on the water supply and power supply system of a city in Central China, As an example, this paper establishes an association response model of infrastructure system.It gives the definition of network association response factor, and studies the change of association factors under random and intentional attacks on urban water supply network and power supply network. The results show that when the attack occurs, the association response The factor increases first and then decreases, and the correlation factor in random attack is larger than the deliberate attack.
