Patent ID: 7672745

Claim:
A method comprising: receiving into a computer-readable memory a plurality of article characteristic values associated with a set of articles having a range of variation as to a plurality of article characteristics resulting from iterations of a process, wherein each of the iterations corresponds to a process condition set of a plurality of process condition sets and wherein each process condition set of the plurality of process condition sets is associated with one or more process optimization criteria; receiving a selection of a predictor characteristic from the plurality of article characteristics; determining a regression model between the predictor characteristic and a selected remaining article characteristics of the plurality of article characteristics; associating points or regions of the regression model with corresponding process condition sets of the plurality of process condition sets; generating and displaying on a display device a diagram of the regression model and the points or regions corresponding to the process condition sets; and displaying at least one of the one or more process optimization criteria in association with identifiers corresponding to the process condition sets.
