Abstract:

Computer-based systems and methods of determining product parameters, performing process control, and/or classifying products are provided. These computer-based systems and methods analyze previous responses to different iterations of one or more tests and, based on this analysis, predict responses to future tests. The predictions are based on a classification and regression tree analysis. Also provided are computer-based systems which are pre-programmed with the results of at least one such analysis and which perform product parameter determination, process control, and/or product classifications based upon those results. The methods and computer systems are particularly well-suited for use in the context of manufacturing galvanneal-coated steel products (e. g. , strips, sheets, plates, rods, wires, and the like), though it is understood that the methods and computer systems are not limited to use on such semi-finished products or their methods of manufacture. To the contrary, these methods and computer systems can be successfully applied to processes of manufacturing any product irrespective of its form.
