Cooperative multi-agent reinforcement learning for multi-area integrated scheduling in wafer fabs

International Journal of Production Research, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 18

Published: Oct. 23, 2024

The existing scheduling methods of wafer fabs focus on single area, achieving local optimisation while failing to realise global due neglecting the coordination multi-area. Therefore, it is necessary consider complex opposing relationships between multi-area caused by constraints such as batch processing, re-entrance, and multiple residency times within areas conduct integrated shorten production cycle time. For this issue, paper proposes a cooperative multi-agent reinforcement learning for scheduling. Aiming at dynamic batching considering arrival lots in multi-area, algorithm presented learn optimal policy firstly. Subsequently, framework raised achieve Furthermore, an adaptive exploration strategy constructed enhance capability solution space time re-entrant property. Moreover, share enhanced Double DQN employed improve generalisation adaptability multi-agent. Finally, experiments demonstrate that proposed method has better comprehensive performance compared previous area-separated methods.
