To overcome the problem of high idling rate and low utilization rate of tractors in loading and unloading at the current stage, the design of the vehicle scheduling problem under the sharing strategy in the freight order circulation system was studied from the freight relationship between service points. With the total mileage of the tractor as the objective function, the vehicle scheduling model with shared strategy was constructed and optimized based on simulated annealing algorithm. Simulation analysis was carried out with two small transport enterprises in Shandong Province as a case. Compared with the common vehicle scheduling mode, the no-load rate, unit freight cost, unit fuel consumption and tractor utilization rate of the shared mode were optimized by 79.6%, 50%, 22.6%, and 171.4%, respectively. The shared strategy swing and hang vehicle scheduling model and its solving algorithm were feasible and effective. In addition, it has good effect in reducing no-load stroke and improving fuel efficiency.
