    The Ultimate Grading and Remanufacturing System (UGRS) is the latest generation of advanced computer programs for lumber grading. It is designed to be a training and research tool that allows grading of lumber according to 1998 NHLA rules and remanufacturing for maximum dollar value. A 32-bit application that runs under all Microsoft Windows operating systems, UGRS provides a sophisticated graphical user interfaces that shows the board and includes all defects and cuttings, grading information, the remanufactured board, and final results. Potential application include online evaluation of lumber grades, research on the effects of grading rules on lumber grades and dollar value, training of graders, and studies of yield optimization and the potential value of lumber due to remanufacturing operation.
