摘　　要：从化工园区内工厂布局角度来看,化工园区属于典型的有向加权网络。构建了化工园区危险品事故的有向加权网络模型,评估化工园区发生爆炸事故时,引发多米诺效应的风险。根据化工园区的网络结构特征,设计了寻找有向加权网络中心节点的算法,评估网络节点即化工园区中仓储库区单元的安全强度。找出多米诺中心后,对其进行严防死守甚至移除,可以有效阻断化工园区危险品事故发生多米诺效应的路径。建立的化工园区危险化学品事故的有向加权网络演化模型为规避化工园区爆炸事故引发多米诺效应严重后果提供了理论依据。From the view of factory layout, chemical industry park is a typically directed weighted network. The paper builds the finite directed weighted network model to assess the risk to trigger a Domino effect, when chemical industry park have the explosion or fire accident. Based on the structure of chemical industry park, the paper designs the algorithm to seek the center of finite directed weighted network, and evaluates the security degree of network node, i.e., the chemical industry park＇s storage reservoir unit. After determining the Domino center, the policymaker can effectively monitor and then block the path of Domino effect in the chemical industry park. The network evolution model of hazardous chemical accident with Domino effect can provide the theory support to avoid risks caused by Domino in the chemical industry park accident.
