Luo Hongke describes the establishment of a nonlinear cost change structure and transportation path model for transportation mode selection in the transportation network. According to the characteristics of building flow and complex network theory, ZengR et al. Transform the influencing factors in the transportation process into border rights. Then calculate the average shortest path to guide the selection of transportation routes, and provide a basis for the selection of transportation routes. ZhangL et al. A mathematical model of emergency logistics with timeliness was established to achieve the purpose of minimum delivery time, and the model was solved by immune ant colony optimization method. DaiJ introduced the minimum time and maximum flow theory to establish a basic model, determine the basic idea of the road transportation route selection of the earthquake disaster emergency logistics system, clarify the path and freight volume constraints, and establish the earthquake disaster emergency road transportation route selection model logistics system
