Abstract:

In order to ensure the safety of the multimodal transportation process of China Railway Express, the WBS-RBS method was selected to identify risks in the entire process of mutimodal transportation of China Railway Express. The traditional WBS-RBS risk matrix assignment algorithm was then improved based on the intuitionistic fuzzy language set, and WBS-RBS intuitionistic fuzzy risk matrix was established. Then, based on the score function of the intuitionistic fuzzy number, combined with the projection method to fuse expert information, the IFWA operator was selected to calculate and rank various risks. Finally, the "Zhengzhou-Alashankou-Aktau Port-Baku Port-Stuttgart" route was selected for the case study,strategies and suggestions for ensuring the safety of multimodal transportation of China Railway Express are put forward from the aspects of international communication, operation management, technical operations, and information connection. The results show that the level of information communication during ticket handover and the level of customs clearance operation management at Alashankou port station, and the social order during basic operation at Stuttgart station are all obvious risks.
