摘要
对于密集存储库中经常出现的同层多台四向穿梭车避堵的组合调度问题,文中提出了一种基于排队论及时间序列分析为基础框架的多车组合调度策略。该策略可以在任务下发的同时实时识别路况信息,结合初始路径进行路径规划,并将潜在障碍形成的交通冲突类型进行归类讨论;结合排队论和时间序列的分析,针对不同冲突类型采取最优的规划策略,从而在任务执行时规避碰撞与拥堵风险。该策略目前被有效运用在实际密集存储库项目中,由项目的任务运行情况显示,该组合调度算法可以有效规避多台四向穿梭车同时作业时的冲突情形,为自动化存储提供了一种新的安全高效的组合调度策略。
To address the combined scheduling challenge of multiple four-way shuttle buses operating on the same floor and to prevent blocking,a multi-vehicle combined scheduling strategy based on queuing theory and time series analysis has been proposed.This strategy is capable of real-time identification of road information upon task issuance,initial path planning,and classification and discussion of traffic conflict types caused by potential obstacles.By integrating queuing theory and time series analysis,the strategy employs optimal planning for different conflict types to avoid collisions and congestion during task execution.This strategy has been effectively implemented in an actual dense warehouse project,where the task operations demonstrate its ability to effectively prevent conflicts when multiple four-way shuttle buses operate simultaneously,thus providing a novel,safe,and efficient combined scheduling solution for automated warehousing systems.
