Structure Survivability Evolution Analysis of Long Distance Water Conveyance Network under Sequential Attack
摘要
Abstract
To explore survivability evolution law of long distance water conveyance system under the deliberate attack,the evolution simulation model is constructed based on the graph theory and the theory of complex network.The long distance water delivery network is established according to its composition,the sequential attack way is determined by analyzing the characteristics of the node and edge attacked;the node clustering coefficient is calculated and the node betweenness centrality is insured to describe the destruction of the node,and use it as the selection criteria of Sequential attack target node.The survivability and key node degree of water network are defined on the basis of water conveyance system efficiency of node attack;Finally,a simulation example is given and the results are as follows:Sequential attack path from the center to the edge of the network,the network survivability is gradually reduced until the network paralysis under the deliberate attack;The whole water conveyance network key nodes is 65,39,50,38 which has greatest impact on system survivability and should focus on monitoring and optimization.This method can provide theoretical guidance for the analysis of the long distance water resources protection and emergency surveillance system关键词
