Process optimization management of hazardous materials transportation based on fishbone diagram and fault tree

In order to improve the management quality of hazardous materials transportation and identify the security management weak link of hazardous materials transportation process, a new method combining with fishbone diagram and fault tree was proposed to improve the hazardous materials transportation process management. Firstly, all the influence factors of hazardous materials transportation process management were systematically analyzed by fishbone diagram method. Then, according to the logic relation of these influence factors, the fishbone diagram was transformed into a fault tree analysis model. By calculating structure importance of the fault tree, the importance degree sort of the influence factors was gained and then the main influence factors such as transportation declaration system defects, multi-department information communication blockade and cross enforcing law were determined. In the end, it provides the corresponding process optimization management strategies of hazardous materials transportation. The research conclusion shows that it can efficiently solve the outstanding problem in hazardous materials transportation process management and prevent hazardous materials transportation accident. In addition, it provides a new idea for using the quantity analysis model to the process optimization management.
