Gas safety entropy model research in Chinese urban gas system
Gas safety is an important part of the urban safe operation. The gas safety entropy (GSE) model and urban gas accident risk factor index are built in this paper based on an analysis of 101 published reports of major urban 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, object, environmental, and management factors. The GSE shows a periodic variation pattern with an average value of 0.082 and a period of 3–4 years. This result can provide a quantitative evaluation method for the urban gas accidents identification of hidden dangers and risk assessment.
期刊介绍：
The broad scope of the journal is process safety. Process safety is defined as the prevention and mitigation of process-related injuries and damage arising from process incidents involving fire, explosion and toxic release. Such undesired events occur in the process industries during the use, storage, manufacture, handling, and transportation of highly hazardous chemicals.
