Research on gas safety entropy model based on gas accidents in China
Gas safety is an important part of the urban safe operation.The occurrence of gas accident brings great threat to people's life and property.The gas safety entropy(GSE)model and gas accident risk factor in-dex are built in this paper based on an analysis of 101 published reports of major gas safety accidents in China from 2011 to 2023.Furthermore,the safety entropy of the gas system is analyzed year by year using the entropy weight method,taking into account personal,physical,environmental,and management factors.The analysis re-sults indicate that the weight of error operation factors is 3.5 times and 7 times greater than that of illegal oper-ation and negative slack.The gas accident safety entropy presents a periodic change rule.The research results can provide objective and scientific theoretical support for the identification,risk assessment and safety man-agement of urban gas safety in China.
