Abstract: Aiming at the integrated scheduling problems of AGV and processing equipment and considering the conflict-free path planning of AGV, a scheduling optimization model was established based on the maximum completion time, AGV running time, and total machine load. And a scheduling optimization model was proposed based on time window and Dijkstra's multi-objective adaptive clustering genetic algorithm. According to the characteristics of the algorithm in different iteration periods, a cross-recombination strategy including adaptive individual cross-probability was proposed. Adaptive population mutation probability was designed. An environmental selection strategy was introduced based on the number of grid divisions and the distances of the expanded grid. The simulation results verified the feasibility and superiority of the algorithm.

摘要: 针对AGV与加工设备的集成调度问题,在考虑AGV无冲突路径规划的情况下,建立了以最大完工时间、AGV运行时间及机器总负荷为优化目标的调度优化模型,提出一种基于时间窗和Dijkstra算法的多目标自适应聚类遗传算法。根据算法在不同迭代时期的特点,提出一种包含自适应个体交叉概率的交叉重组策略;设计了自适应种群变异概率;引入基于网格划分数和扩容网格距离的环境选择策略。仿真结果验证了算法的可行性和优越性。
