摘要: 自动导引车(AGV)在生产车间的应用,给车间调度带来许多额外的需要解决的实际问题,如运输任务AGV分配、AGV电量约束、AGV数量约束等,使得其调度问题更加复杂和困难。针对多AGV运输工件的作业车间调度的特点和约束条件,建立了考虑充电约束的多AGV运输工件的作业车间调度模型,通过虚拟设备的方法设计了工件分配和AGV运输任务的两段染色体编码,设计了工件分配和AGV任务分配的集成解码方法,并设计了改进遗传算法进行求解,进一步分析了AGV数量、AGV电量和运输时间等因素对优化目标的影响,最后通过作业车间典型算例仿真验证了模型与算法的有效性。

Abstract: With the application of Automatic Guided Vehicle (AGV) in the production workshop,new practical problems such as AGV assignment,AGV power constraint and AGV quantity constraint have been brought in production management of the workshop.According to the characteristics and constraints of job shop scheduling with multiple AGVs,the job shop scheduling model considering multiple AGVs with  charging constraint was established.The two segment chromosome coding of job assignment and AGV transportation task was designed through virtual equipment.The decoding method integrating job allocation and AGV task allocation was designed,and an improved genetic algorithm was designed.The influence of AGVs quantity,AGV power and transportation time on the optimization objective was further analyzed.The model and algorithm were verified by simulation using job shop instances.

Key words: job shop, scheduling, automatic guided vehicle, transportation, charging
