| 摘 要： | 综合运用图论和复杂网络理论，构建了长距离输水系统网络拓扑结构图，选取破坏效率较高的节点攻击，分别在输水系统网络拓扑结构信息未知、部分已知和全部已知的情况下展开随机攻击、条件攻击和蓄意攻击，进行了3种攻击策略下输水系统抗毁性的仿真试验，并在网络拓扑结构信息完全获取的情况下采用度、介数和接近中心性3种特征参数量化节点重要性，分析了输水系统对不同节点重要度参数的抗毁性响应。研究结果表明:不同攻击策略下的破坏效率呈现为蓄意攻击>条件攻击>随机攻击，对拓扑网络结构的信息获取程度越大，攻击效率越高；完全信息攻击下的输水系统抗毁性受节点的介数影响较大，受节点的度影响较小。本研究可为长距离输水系统的重要设施识别及保护提供理论支撑。

| Abstract: | Graph and complex network theory were used to construct the network topology of long-distance water delivery system. Node attack was selected due to its higher destruction efficiency. Under the condition of having unknown, partially known and fully known about the network topology, the attack strategies of random attack, conditional attack and deliberate attack were implemented respectively, and then the invulnerability of the water delivery system under different attack strategies was evaluated. The degree, betweenness and closeness centrality were furtherly used to quantify the node importance under the condition of having fully known about network topology, then the response of water delivery system invulnerability to different node importance indexes was analyzed. The results show that deliberate attack is the most efficient while the random attack has the lowest efficiency, and as information acquisition increases, the attack efficiency increases correspondingly. Node betweenness has the greatest impact on water delivery system invulnerability while node degree has the least impact. This study can provide theoretical support for the identification and protection of important facilities in long-distance water delivery systems. |
