Evaluation of safety risk of major hazardous installations in coating enterprises based on set pair analysis
This paper proposes an evaluation model for the safety risk levels of major hazard installations in coating enterprises,and constructs an evaluation index system of major hazard installations from aspects of inherent risk factors and risk offsetting factors.The combined weighting was used to judge the weights of index at all levels,and the connection number function was established by set pair analysis to calculate the single connection number and overall connection number of each index.The safety risk level of major hazard installations was determined.The results show that this model can effectively solve the difficult problems of quantitative evaluation of major hazard installations.This model can not only analyze the existing safety situation of coating enterprises,but also make a reasonable prediction for the future safety trend of enterprises,which can provide theoretical support for the safety supervision and accident prevention of major hazard installations.
