To improve the safety supervision level of special equipment,a coupled model for special equipment safety risk warning analysis called SEM-ANP-CM is constructed by combining structural equation modeling(SEM),analytic network process(ANP),and cloud model(CM).Based on weighted membership values,the warning levels are divided into five levels:no warning,fourth level warning,third level warning,second level warning,and first level warning.The coupling model was applied to the safety risk warning analysis of special equipment in North China,and the results showed that the weighted membership values of Beijing,Inner Mongolia,Tianjin,and Hebei were between[1.5,2.5),belonging to the fourth level warning state.Shanxi had the worst safety status,with a weighted membership value between[2.5,3.5),belonging to the third level warning state.
