Research on the Intelligence Control of the Laser Welding Manufacturing System Using Multi-Agents

The laser welding flexible manufacturing system (LWFMS) is a complex flexible manufacturing system which contains several robots and several workstations. In order to ensure the laser welding quality, an effective control model with intelligence is necessary. Based on the characteristics of the laser welding manufacturing system, a multi-agent system model has been built up on this system. The built model consists of three levels: the higher level, the middle level and the lower level. The production supervisory agent in the higher level manages the other level´s agents. The middle layer consists of task management agent and system monitor agent which assign the tasks received from the high level to the lower agents. The lower level composes of exertion agents. The model proposed in this paper enhances the intelligence of the laser welding system and ensures the welding quality.
