Based on intelligent agent technology, a new method for dynamic scheduling of chip manufacturing production lines is proposed, which integrates feeding scheduling, workpiece scheduling, and equipment maintenance scheduling. Firstly, a dynamic scheduling model based on intelligent agents is proposed, which includes management agents, feeding agents, workpiece agents, equipment agents, transportation agents, and personnel agents. The feeding intelligent agent is used to achieve feeding control, and workpiece scheduling is achieved through negotiation between the workpiece intelligent agent and the device intelligent agent. Equipment maintenance scheduling is achieved by the device intelligent agent. The mechanism has been explained in detail in terms of scheduling control algorithms and other aspects. This mechanism can achieve real-time control and dynamic scheduling at the workshop level based on the system operation status. Finally, experiments have shown that this method effectively reduces the impact of equipment failures and other disturbance factors on system operation.
