Research on University Laboratory Safety Risk Assessment Based on AHP-EWM-TOPSIS model
According to the inspection key points of the Laboratory Safety Inspection List of Universities (2023 edition) issued by the Ministry of Education,40 evaluation indicators were selected,22 key indicators were optimized and screened by Delphi method,and subjective and objective weights were calculated scientifically by AHP and entropy weight method. The final weight is determined by integrating subjective and objective weight assignment methods. Finally,TOPSIS method is used to evaluate the safety risk of 15 experi-mental centers in a certain school,and the evaluation ranking results are obtained. After the actual situation analysis,the laboratory safety risk assessment method based on AHP-EWM-TOPSIS model is constructed,which corrects the subjective bias,realizes the sys-tem hierarchy and objective assignment for comprehensive analysis of index weights,and solves the problem of comprehensive evalua-tion under multiple indicators.
