基于系统动力学的危险化学品运输风险因素研究
Research on risk factors of hazardous chemicals transportation based on system dynamics
摘要
Abstract
In order to reduce the frequency of hazardous chemicals transportation accidents and avoid the risk of hazardous chemicals transportation,based on the system dynamics model,a risk factor index system of hazardous chemicals transportation was constructed from the four dimensions of man-machine-environment-management,the AHP method was used to assign the index weights,and parametric equations were built combining the causal relationship between risk factors.Vensim was used to simulate the change trend of the risk level of hazardous chemicals transportation,and the influence of the changes in the value of single factor variables and the weight value of the man-machine-environment-pipe subsystem on the whole model was determined.The results show that the changes in risk factors such as weak safety awareness,equipment failure,and the weight changes of the four subsystems of man-machine-environment-management will affect the risk level of hazardous chemicals transportation,and the impact degree of the four subsystems of man,machine,environment and management.The results can provide a certain reference for reducing the risk in the process of hazardous chemicals transportation and formulating the prevention strategy of hazardous chemicals transportation accidents.关键词
