Analysis of Safety State of Dangerous Goods Transport System Based on Catastrophe Theory

On the basis of catastrophe theory predecessors studied, the paper uses catastrophe theory to talk over accidents causation models of dangerous goods transport, analyzes basic elements of accident and their interrelations, all factors are concluded to be within the dangerous goods transport accident system of "human-machine-environment". According to the exploration, the risk degree of dangerous goods transport system is divided into safety, critical, dangerous state, and establish model of safety decision-making and safety measures. Construct mathematical model of safety degree and safety state. Catastrophe theory can be used to reveal safety state of dangerous goods transport and identify key risk factors, to take measures to the key risk factors which can improve the safety situation. So as to enhance the system's safety status and avoid accidents of dangerous goods transport.
