Research on Safety Management of Inland River Dangerous Chemicals Transportation System Based on System Dynamics and Principal Component Analysis

This paper proposes a new method to study the safety of inland river hazardous chemical transportation under dynamic conditions based on the principles of system dynamics by analyzing the related theories of hazardous chemical transportation and comparing the traditional static hazard assessment methods. The system dynamics model of the inland river hazardous chemicals transportation system is constructed in this paper. According to Vensim_PLE, relevant data are obtained by changing the growth rate of the safety input of various factors. Using the principal component analysis (PSC) analysis data to verify the accuracy of the model and study the impact of various factors on the safety of the transportation system. The result shows that human factors and management factors have a greater influence on the safety of the transportation system. It is important to change the input indicators of human factors and management factors to improve safety.
