Agent technology is widely used in intelligent manufacturing and digital workshop as a new method to solve complex, dynamic and distributed artiϐicial intelligence application problems. This paper ϐirstly summarizes the application steps of Agent technology in 3 aspects of modeling, simulation and monitoring of intelligent manufacturing system on the basis of a brief description of multi-agent system. Then, based on reinforcement learning theory, a multi-agent collaborative algorithm SRL_M3DDPG based on state representation learning is proposed.Finally, the algorithm model is tested and applied to the smart shop scheduling problem. The learning curve of the SRL_M3DDPG algorithm in the example remains relatively stable after the 3400th round, and the maximum completion time of the scheduling is 29. Comparing with other composite scheduling rules, the delay rate of this paper’s algorithmic model is the lowest, which is only 15.47%, which indicates that the algorithm is able to signiϐicantly reduce the delay rate of the workpiece. In addition, this paper’s algorithm achieves better results in adaptive intelligent manufacturing workshop scheduling, ϐinding the shortest machining completion time of 221 unit time, which can adapt to the dynamic intelligent manufacturing workshop environment.
