Researchers have developed a novel approach called TN-DCR (Transport-Network-Aware Dynamic Congestion Representation) to optimize route scheduling in semiconductor fabrication plants. This system uses a directed graph of historical transport segments to predict delivery times and congestion risks. By integrating structural route information, network-wide congestion context, and bottleneck exposure, TN-DCR feeds into regressors and classifiers that estimate queue and transfer times. This information is then used in a risk-constrained scheduling model to minimize predicted delivery time while bounding extreme congestion probability. In closed-loop evaluations, this method resulted in a 16.4% reduction in mean delivery time and a 22.6% decrease in internal resource waiting time, with throughput remaining largely unchanged. AI
