Abstract
[Objective]Currently,in the practice of consumer product safety risk assessment,the risk matrix method is mainly used at home and abroad to determine the risk category,and serves as reference for decision-making;however,this method has limitations in risk level determination.[Methods]Tries to introduce the idea of Bayesian Networks(BNs),and puts forward a kind of improved consumer product safety risk assessment method,which can solve the limitations of the risk matrix method in risk determination.[Results]By comparing the risk matrix method and BNs,the advantages of the application of the BNs in the risk assessment of consumer product safety are elaborated in detail,and the optimization and improvement of the typical EU consumer product risk assessment method(RAPEX)is shown with the help of a simple case study of the BNs.[Conclusion]The use of the BNs idea can optimize the RAPEX risk matrix method,providing quantitative and auditable risk level determination results,which not only enhances the science and reliability of risk management decisions,but also improves the efficiency of the use of regulatory resources.关键词
