摘要

燃气安全是城市安全运行的重要组成部分。本文在分析2011 - 2023年中国已发表的101份重大城市燃气安全事故报告的基础上，建立了燃气安全熵模型和城市燃气事故风险因子指数。在此基础上，综合考虑人、物、环境、管理等因素，采用熵权法对燃气系统的安全熵进行了逐年分析。GSE呈周期性变化，平均值为0.082，周期为3 ~ 4年。该结果可为城市燃气事故隐患识别和风险评价提供定量评价方法。

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.
