Abstract: To improve the production control performance of the manufacturing system, a hybrid control model based on architecture of MultiAgent System (MAS) was constructed. This model consisted of three layers: the management Agent layer, the cell Agent layer and the execution Agent layer. The management Agent layer was in charge of scheduling, coordinating and managing all Agents. Collaboration among the cell Agents of cell Agent layer was implemented by a common database. The execution Agents were responsible for the hardware of the control system. According to the local resources information and current status, they accepted the tasks assigned by the cell Agents and resolved the tasks. Agents in the same layer were in distributed structure. The production control system based on MAS improved realtime characteristics and robustness of the manufacturing system. Finally, the validity of the model was demonstrated by an experiment on the laser tailored blank welding production control system.
