A method for controlling an industrial process. The method includes outputting a plurality of parameters from a process for manufacture of a substance. The method also uses each of the plurality of parameters in a computer aided process, which compares at least two of the plurality of parameters against a training set of parameters. The training set of parameters is generally predetermined. A step of determining if the at least two of the plurality of parameters are within a predetermined range of the training set of parameters also is included. Additionally, the method includes outputting a result based upon the determining step.
