Abstract：To cope with the overcrowdingproblems of gates， yards and road transportation networks caused by unbalanced arrival of ports during the peak hours of the import and export container block. It is proposed that under the effective appointment system， by dividing the appointment time window and the reservation share of a certain period of time. the principle of maximizing the benefit is adopted， and the dispatching plan of the port deliver and pickup Containers that reaches the task at each dock yard is optimized. The model is solved by a genetic algorithm with improved design. Finally， the effectiveness of the model and algorithm is verified by an example. The results of the example show that the constructed model can effectively reduce the total number of trucks and the usage time of all trucks which can improve the economic benefits for the port and transportation enterprises.
