摘要
针对多辆自动导引运输车在实际场景中的调度问题,为提高车间作业系统的效率,文中以AGV运行时间最短为目标,将多种群遗传算法引入到两阶段路径规划策略。先离线生成最短路径库缩减问题规模,降低在线调度的运算负担。当离线路径库不能满足调度要求时,再通过多种群遗传算法在离线路径库的基础上进行全局的路径规划。初步实验证明,该策略较好地提高了AGV调度系统的效率和鲁棒性,是一种能适用于不同地图的通用调度策略。
Direct at the scheduling problem of several automated guided vehicles in real scene,multi group genetic algorithm is introduced to the two-stage path planning strategy to improve the efficiency of the workshop operation system,which aims at the shortest run time of AGV. First,the shortest path library is generated in the off-line phase,which is used to reduce the scale of the problem,and then reduce the computing burden of online scheduling.When the off-line path library cannot meet the requirements of scheduling,the global path planning is carried out on the basis of the off-line path library,by invoke the multi-population genetic algorithm. The preliminary experiments show that this strategy has well improved the efficiency and robustness of AGV scheduling system,and it is a general scheduling strategy suitable for different maps.
