摘要
风险防治和隐患排查是城市安全的重要组成部分。由于各行业领域中潜在的风险类型和分布存在着很大差异,因此在风险防治工作中需要考虑差异性,并有针对性地制定行业风险防控措施。研究了城市安全生产风险的行业分布差异性,提出了行业安全风险结构的概念,在行业风险分布标准化的基础上定义了行业安全风险向量,基于信息熵理论给出了行业风险熵和风险特异度的量化指标。基于对数万个不同企业风险和隐患案例分析的结果,发现风险向量、风险熵、风险特异度等几个参数的确定有助于对安全生产风险进行行业内和行业间的对比研究,从而为行业安全风险分类监控提供依据。
Risk prevention and hidden danger identification are important to urban safety.According to current laws and regulations on safety production and emergency management in China,the responsible subjects of safety management are those departments that are directly involved in risks and hidden dangers.In a comprehensive city there are great differences in the types and distributions of potential risks among industries.These differences should be taken into account so that targeted risk prevention and control measures can be formulated accordingly.This paper studies the distribution differences of potential safety risks in industries,proposes a concept of industry safety risk structure,defines an industry safety risk vector,and gives the quantification indexes of industry risk entropy and risk specificity by means of information entropy theory.Based on the analysis results of tens of thousands of cases it is found that determination of safety risk vector,industry risk entropy,and risk specificity is conducive to the comparative study of safety risks within and between industries and provides a basis for the classified monitoring of industrial safety risks.
