摘　　要：在离散网格环境下设计基于自动导引车辆(automatic guided vehicle,AGV)的物流分拣系统,基于中央控制器的集中控制策略,采用Label Correcting算法对AGV进行动态路径规划,基于交叉口不停留策略对系统内AGV进行交通控制。仿真实验结果表明:所提出的分拣系统能够适用于大规模的物流包裹分拣;路径更新间隔时间对分拣系统运行性能和仿真运行效率具有显著影响,路径更新间隔时间越小,系统运行性能越好,但仿真运行所耗时间越长,在实际应用中越无法保证实时性的要求。因此,在实际应用中确定路径更新间隔时间时,需综合考虑系统运行性能和仿真运行效率两方面指标。In this study,an automated guided vehicle(AGV)-based logistics sorting system is designed in a discrete grid environment.Based on a centralized control strategy of the central controller,the dynamic path planning of AGVs is performed using the Label Correcting algorithm.Moreover,the no-lingering strategy is used at intersections to control the traffic of AGVs in the system.Simulation results show that the proposed sorting system can be applied to large-scale logistics sorting.The update interval of paths has a considerable impact on the performance of the sorting system and the efficiency of the simulation.A shorter update interval signifies improved performance of the system,and the longer simulation runs.However,real-time requirements cannot be ensured in practical applications.Hence,the performance of the sorting system and efficiency of the simulation must be comprehensively considered when determining the update interval of paths in practical applications.
