英文摘要：

Considering the characteristics and restrictions on the container transportation with dumping trailers, the vehicle routing optimization model is built based on the research of the vehicle routing optimization problem and the related algorithm. The model analyzes the vehicle routing optimization problem under hard time constraint, and the model was solved by the simulated annealing algorithm. It is proved that the model can solve the traction vehicle scheduling problem of the dumping trailers transportation. Finally, the model is applied to the actual case, and it is proved that the simulated annealing algorithm is feasible and effective.
