Integrated Scheduling of Flexible Job Shop Considering AGV Quantity Configuration
The automatic guided vehicle(AGV),as a crucial equipment supporting production logistics in flexible job shop,has been widely adopted in the production organization of many enterprises.The quantity configuration of AGV directly impact the implementation of workshop transportation tasks and the smooth progress of production tasks.Addressing the issue of suboptimal AGV quantity configuration in flexible job shop,leading to delayed response to transportation tasks or underutilization of AGV re-sources,this article aims to minimize the maximum completion time and AGV quantity.It establishes an integrated scheduling model considering AGV quantity configuration and designs an improved NSGA-Ⅱ algorithm based on three-level encoding of pro-cesses,processing equipment,and AGVs for solution generation.Through numerical experiments and analysis,the optimal AGV quantity configuration and integrated scheduling solution for flexible job shop are obtained.This provides theoretical support and practical guidance for enterprises to efficiently and rationally manage and schedule production equipment,aiding in relevant deci-sion-making processes.
