基于多层次灰色关联分析的道路危险货物运输企业安全管理综合评价

Comprehensive Evaluation on Safety Management of Road Dangerous Goods Transportation Enterprises Based on Multi-level Gray Relational Analysis

对危险货物道路运输企业开展安全综合评价研究,有助于提高企业的安全管理水平,进而减少道路安全事故的发生。本文基于对危险货物道路运输安全风险因素的分析,运用AHP法构建了危险货物道路运输企业安全综合评价指标体系,并对各评价指标赋予了权重。结合实例,运用灰色关联分析模型计算出每一个被评价企业与虚拟的"最优企业"之间的关联度大小,从而确定出各个被评价企业安全管理水平的优劣次序,为危险货物道路运输企业安全综合评价提供了参考。

It is helpful to improve the safety management level of enterprises to carry out the comprehensive evaluation on safety management of the road transport enterprises of dangerous goods, and to reduce road safety accidents. Based on the analysis of the risk factors of road transport of dangerous goods, this paper constructs a comprehensive evaluation index system for the safety of the road transport enterprise with the AHP method, and gives the weight of each evaluation index. Combined with the instance, the correlation size between each evaluated enterprise and the virtual ＂best enterprise＂ is calculated by using gray relational analysis model, so as to identify the pros and cons of the safety management level of each evaluated enterprise, with providing reference for comprehensive safety evaluation of road transportation enterprises of dangerous goods.
