摘　　要：安全风险评估对于确定工厂的风险等级,采取有针对性的措施降低安全风险具有重要意义。基于安全风险因子表(SRFT),提出了一种基于加权模糊Petri网(WFPN)的安全风险评估方法,根据安全风险评估因素之间的不同关系,建立了两种安全风险评估WFPN模型,并提出了基于矩阵运算的安全风险推理方法。结果表明,正确确定和建模风险因素之间的关系对安全风险评估具有重要意义。Safety risk assessment is of great significance to determine the risk level of the factory and take targeted measures to reduce the safety risk. Based on the safety risk factor table(SRFT), a safety risk assessment method based on weighted fuzzy petri net(WFPN) is proposed. According to the different relationships between safety risk assessment factors, two safety risk assessment WFPN models are established, and a safety risk reasoning method based on matrix operation is proposed. The results show that correctly determining and modeling the relationship between risk factors is of great significance to safety risk assessment.
