Abstract:

In order to study the effect of buffer space setting on operation coordination of handling equipment in automated container terminals, an integrated scheduling optimization model is established based on the new handling technology of “Double trolley Quay Crane+AGV+Buffer bracket + Automated Rail Mounted Gantry Crane” by using the theory about flexible flow shop with limited buffer. The genetic algorithm which generates initial solution by NEH heuristic algorithm is designed to solve the model, and the corresponding equipment scheduling optimization scheme and completion time are obtained. By comparing the results of GA and PSO, it is shown that the model and the algorithm proposed in this paper are effective. Furthermore, the make span under different restriction of the buffer space and different number of AGVs are analyzed, and the optimal buffer capacity and the optimal number of AGVs are given. The analysis results show that the buffer space plays an important role in improving equipment coordination and reducing optimizing operation time.
