1. A method for automatically correcting book portion mismatches in a book binding operation, the method comprising:
receiving input signals from one or more online sensors corresponding to a sequence of first book portions being conveyed along a first assembly channel leading into a book binding stage and corresponding to a sequence of second book portions being conveyed along a second assembly channel leading into the book binding stage;
predicting a mismatch state between a first book portion and a second book portion based on the respective sequences and with respect to expected first and second sequences dependent on a defined book assembly batch;
determining an intervention event corresponding to the predicted mismatch state, from among a plurality of intervention events each respectively corresponding to one or more of a plurality of mismatch states; and
automatically executing the determined intervention event corresponding to the predicted mismatch state;
at least one of the plurality of intervention events comprising a selective routing of the first book portion and/or the second book portion associated with the predicted mismatch state from the respective assembly channel into a correction channel and reinsertion of the first book portion and/or the second book portion associated with the predicted mismatch state into the respective assembly channel corresponding to a modified version of the respective sequence,
wherein the method further comprises:
a model development stage comprising, for each of a plurality of input data sets received over time and comprising inputs from the one or more online sensors, correlating the input data sets, and any predicted mismatches and/or performed intervention events, with determined outcomes at a corresponding book binding stage; and
for a current book binding operation, predicting the mismatch state between the first book portion and the second book portion, and further determining the intervention event corresponding to the predicted mismatch state, based on the associated inputs from the one or more online sensors and by reference to correlated data sets from the model development stage.
