Abstract:

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.
