基于改进FAHP-Entropy法的危险品仓储安全评价

Storage safety evaluation of hazardous materials based on improved FAHP-Entropy method

为提升企业危险品仓储安全风险识别能力,针对危险品特殊属性及其仓储安全管理特点,提出基于改进的模糊层次分析法(FAHP)与熵权法(Entropy)的危险品仓储安全评价机制。首先,从人员、管理、物料与设备、环境4个方面建立评价指标体系;然后,基于改进的FAHP和Entropy法,确定指标的综合权重,并结合三角模糊数(TRFN)确定模糊关系矩阵;最后,以广东省某危险品物流企业为例,通过模糊评价模型得出最终安全评价结果。结果表明:该企业危险品仓储安全综合评价结果以及人员安全、管理安全、物料与设备安全、环境安全等4个一级指标评价结果均属于“较安全”水平,其中物料与设备方面评分最高。该安全评价机制基于改进的FAHP-Entropy模型,对比分析指标体系与评价结果,能够实现危险品仓储管理的关键风险因素识别,有助于提高企业危险品仓储管理安全水平。

Aiming at the special properties of hazardous materials and the characteristics of storage safety management,in order to improve the risk identification ability and management level of hazardous materials storage safety,an evaluation method for hazardous materials storage safety based on improved FAHP-Entropy was proposed.Firstly,the evaluation index system was established from four aspects:personnel,management,materials and equipment,and environmental effect.Secondly,the improved FAHP method was used to determine the subjective weight of the indicators,and the Entropy method was used to determine the objective weight of the indicators.Based on the concept of distance function,the subjective weight and objective weight were integrated to obtain the comprehensive weight of each indicator.Thirdly,TRFN and fuzzy statistics were used to determine the fuzzy relation matrix.Finally,the fuzzy evaluation model was established and used to get the final evaluation result.This safety evaluation model has been used to evaluate the storage safety of hazardous materials in a hazardous materials logistics enterprise in Guangdong.The comprehensive evaluation results of the enterprise's storage safety of hazardous materials and the evaluation results of four first-level indicators,including personnel safety,management safety,material and equipment safety,and environmental safety,all belong to the"relatively safe"level.Among them,materials and equipment have the highest score.Based on the improved FAHP-Entropy model,the safety evaluation model can realize the identification of key risk factors in the safety management of the hazardous materials storage by comparing analyzing the index system and the evaluation results.This is helpful to improve the safety level of the enterprise's hazardous materials storage safety management.
