In recent years, to adapt to the rapid growth of container throughput, the new loading and unloading technology of double cycling is beginning to be used in ports, because it can improve the loading and unloading efficiency of the terminal. However, the ports are currently lack of a corresponding and suitable container yard storage strategy, and according to the characteristics of the new loading and unloading process of double cycling, this paper proposes two strategies of the separate stacking strategy of import and export containers in the same vessel with different container areas and the mixed stacking strategy in the same vessel with the same container areas. The mixed stacking strategy of the same vessel with the same container area can be divided into two methods: the same vessel with the same ship-bay positions and the same vessel with different ship-bay positions, and the cost of the latter method is higher than the former, because the yard cranes and the trucks need to move back and forth frequently. Therefore, this paper focuses on the comparison and analysis of the two strategies of the same vessel with different container areas and the same vessel with the same ship-bay positions. The FlexTerm simulation modelling test shows that it is not easy to generate traffic congestion and the loading and unloading operation time is shorter if the strategy of the same vessel with different container areas is applied.
