Researchers have developed a novel time-lag-aware deep reinforcement learning approach to optimize scheduling in prefabricated module factories. This method specifically addresses the significant delays caused by post-operation processes like concrete curing and testing, which can inflate production times by up to 67% if not accounted for. The adapted dual-attention deep reinforcement learning solver incorporates lag-aware dynamics, anticipatory lag features, and liveness-masked embeddings to achieve a strong solver-free scheduling performance, reaching within 4% of constraint-programming references and outperforming traditional dispatching rules and genetic algorithms.
