  • 摘要:Aiming at the problem of urban water supply network protection under terrorist attack, a new comprehensive value evaluation method for important nodes of water supply network is proposed. Combined with the characteristics of terrorist attacks, Epanet and Aloha were used to simulate the changes in the efficiency of the water supply network and the consequences of secondary disasters after the node was destroyed, and a comprehensive value evaluation model based on the node's own value, system value and indirect value was constructed. Taking an urban water supply network in Hubei Province as an example, the results can get the following conclusions: ①Compared with the buried water pipeline, the water supply plant as the source of the urban water supply network is the key target of terrorists; ②the calculation results show the comprehensive value of different water plants The gap is huge, and the comprehensive value of water plant 3 is nearly 5 times that of water plant 4; ③ the greater the comprehensive value of the water plant, the greater the terrorist attack revenue and the higher the probability of attack. Therefore, when responding to terrorist attacks, the comprehensive value should be High water plants provide more protection resources.
