面向多运输任务的节能单负载AGV路径规划研究

节能路径规划已被证明是提高自动导引运输车(automated guided vehicle,AGV)使用过程能效,促进生产车间节能的一种可行方法.目前从路径规划角度开展的AGV能耗优化研究主要面向单项运输任务,很少涉及多项运输任务.为此,以单负载AGV为研究对象,建立了面向多运输任务,以运输距离和能耗为优化目标的节能A...

Energy-efficient path planning for a single-load AGV executing multiple transport tasks

Energy-efficient path planning has been proved to be a feasible approach to improve the energy efficiency of an automated guided vehicle(AGV)and promote the energy saving of a manufacturing workshop.Current research on AGV energy consumption(EC)optimization from the perspective of path planning mainly focuses on a single transport task,and rarely involves multiple transport tasks.To fill the gap,with a single load AGV as the research object,an energy-efficient AGV path planning model is established,which is oriented to multiple transport tasks and takes transport distance and EC as the optimization objectives.Then,a two-stage solution method is proposed.In the first stage,the energy-efficient AGV path planning is executed for the load transport stage associated with each transport task,and the possible no-load transport stages,to obtain the corresponding optimal paths.In the second stage,the non-dominated sorting genetic algorithm-II is adopted to determine the optimal transport task execution order and select the best transport path for each transport stage.Finally,the case study verifies the energy-saving effect of the presented model.
