The invention discloses a
semiconductor wafer manufacturing factory logistics jam prediction method and
system, and relates to the technical field of
semiconductor manufacturing
process optimization, and the method comprises the steps: collecting and preprocessing historical logistics data of a
semiconductor manufacturing intelligent factory, carrying out the spatial-temporal
feature fusion of the preprocessed data, generating high-dimensional representation data, and carrying out the prediction of the logistics jam of the semiconductor
wafer manufacturing factory. Performing coding
feature extraction processing on the high-dimensional representation data, extracting spatio-temporal features through a
time sequence dynamic sensing operation and a
spatial relationship self-adaptive operation, performing spatio-temporal
feature fusion processing, performing cross-
sequence feature integration on a
processing result and complex spatio-temporal features, and performing decoding prediction processing on the integrated features, and through a causal constraint attention mechanism and cross-sequence correlation modeling, predicting a logistics state
matrix sequence, and based on the logistics state
matrix sequence, carrying out congestion state determination. According to the method, high-precision prediction and quick response of logistics blockage of the
semiconductor factory are realized, and the problems of spatial-temporal characteristic splitting, response
lag and high
false alarm rate of a traditional method are solved.
