Visual production scheduling technology for the complex product assembly process

To solve the problems such as unreasonable assembly planning, tough dynamic scheduling, lacking of process monitoring and information management tools in complex product assembly, the visual production scheduling technology was proposed. By analyzing the characteristic of complex product assembly process, the visual modeling method of assembly process based on workflow was presented, and the scheduling model of complex product assembly was raised on the basis of assembly process model. Aiming at the assembly plan scheduling, heuristic scheduling algorithm was proposed. Aiming at the disturbance problem, the dynamic scheduling algorithm was raised. Furthermore, visual assembly scheduling method and information management method were discussed, and visual monitoring of assembly process, dynamic scheduling as well as scheduling information management were realized. The proposed technology and method were proved effectively by actual applications.
