基于改进解释结构模型的爆炸性粉尘作业场所风险评价

为了对爆炸性粉尘作业场所进行风险评价,从环境、设备、组织管理三个层面分析爆炸性粉尘爆炸作业场所的安全隐患。采用改进解释结构模型(ISM)分析各个风险因素之间的二元关系,构建3级递阶结构模型,将模型中各层级的影响因素赋予权重值并整合计算,得到权重分析表。结果表明:粉尘爆炸作业场所的风险因素主要分为表层因素、中间因素和深层因素三个层面,这三个层面主要与企业的积尘措施、动火作业制度、安全意识和安全检查制度有关。创新性地在传统解释结构模型的基础上进行权重的赋值计算,将定性和定量分析的方法相结合,在很大程度上弥补了传统方法的弊端,所得到的结果更具科学性。

Study on Risk Factors of Metal Dust Explosion Accidents Based on ISM and AHP

In order to evaluate the risk of explosive dust workplaces the hidden dangers of explosive dust workplaces are analyzed from three aspects of environment, equipment and organization and management. The improved Interpretative Structural Model(ISM) is applied to analyze the binary relationship among risk factors, and construct a three-level hierarchical structure model, in which the influencing factors of each level in the model are given weight value and integrated calculation to obtain the weight analysis table. The results show that the risk factors of dust explosion workplace are mainly divided into three levels, surface factors, intermediate factors and deep factors and these three levels are mainly related to dust accumulation measures, fire operation system, safety awareness and safety inspection system. The assignment of weights is carried out novelty on the basis of traditional interpretation of structural modes, combined with qualitative and quantitative analysis methods, it can largely remedy the drawbacks of traditional methods, and the results obtained are more scientific.
