Risk Evaluation of Hazardous Chemical Road Transportation Accidents Based on a Combined Empowerment-Cloud Model
Source abstract
Abstract
To improve the accuracy of the risk evaluation results of hazardous chemical road transportation systems, an accident risk evaluation model based on the combined weight-cloud model is proposed to address the problems of ambiguity and randomness in the risk factors for hazardous chemical road transportation accidents. First, incorporating the risk factor identification results, the risk evaluation index system for hazardous chemical road transportation accidents is established. On the basis of determining the subjective and objective weights of the indices by using the analytic hierarchy process and entropy weight method, the comprehensive weights of the evaluation indices are calculated by the linear weighting method. Then, the weighting results are combined with the cloud model to calculate the risk level of the evaluation indices at all levels and to output the results in the form of a risk cloud diagram to visually determine the risk level of hazardous chemical road transportation. Finally, the model is applied to evaluate the accident risk in an example. The results demonstrate that the model is both practical and applicable in the evaluation of the risk of hazardous chemical road transportation accidents. The evaluation results can provide a valuable reference for hazardous chemical road transportation enterprises to prevent accidents.
