基于网络层次分析法的石油化工设施安全风险评估

Security Risk Assessment of Petrochemical Facilities Based on Analytic Network Process

为评估石油化工设施的安全风险,提出了一种基于网络层次分析法的安全风险评估模型。在构建石油化工设施安全风险网络层次分析模型的基础上,采用Saaty标度法对安全风险参数进行量化,利用SD软件对安全风险参数进行排序。仿真结果表明,网络层次分析法考虑了安全风险参数之间的相互作用和相互影响,能改进基于线性组合关系的递阶层次分析模型的不足,评估结果可为石油化工企业制定安全风险管理措施提供决策依据。

To assess security risk of petrochemical facilities,a model of security risk assessment based on analytic network process is proposed in this paper.On the basis of establishing analytic network model,Saaty scale method is adopted to quantify security risk parameters,and SuperDecision software is used to calculate the parameter’s rank ordering.Simulation results show that analytic network process considers the mutual interactions of security risk parameters,and could modify the shortage of hierarchical lineraty assessment model,which could provide decision-making references for petrochemical plants to make security risk management countermeasures.
