ABSTRACT:
A method and apparatus are disclosed for evaluating the performance of a Linear Program model of an operation. The significant properties of the current invention include the use of a historical record or operating data as a means to improve the evaluation of the Linear Program model quality. The historical record of operating data also allows a more reliable means for calculating corrected Linear Program model coefficients. Related applications are disclosed for viewing graphically both the uncorrected and the corrected Linear Program model's performance. Statistical methods are disclosed as further aids in understanding both the uncorrected and corrected Linear Program model's performance.
