英文摘要	The Automatic Guided Vehicle (AGV) sorting system is a new way of sorting. Path planning is the key part to improve sorting efficiency of the system. In the existing methods, the multiflow network path planning method obtains optimal paths by transforming path planning problems into integer linear programming problems and solving them. However, due to the huge amount of calculation, it is hard to ensure the real-time performance and use the method in practice. In this paper, a Calculation Time Prediction-based Multiflow Network path planning method (CTPMN) is proposed to deal with the problem. Firstly, a new operating model is proposed, in which the time window of the AGV moving can be set according to the predicted calculation time of the path planning method. And then a support vector machine-based algorithm is used to learn the predicted calculation time based on the size of sorting area, number of sorting tasks and the maximum task distance. In addition, a task decomposition strategy is put forward to eliminate the constraint that the destination of any two tasks in the multi-flow network method cannot be the same. Finally, the effectiveness of the proposed method is verified by simulation experiments.
