Description: This paper describes an expert system computer program which will determine the optimum way to edge and trim a hardwood board so as to yield the highest dollar value based on the grade, size of each board, and current market prices. The program uses the Automated Hardwood Lumber Grading Program written by Klinkhachorn, et al. for determining the grade of each board based on the National Hardwood Lumber Association Rules. It checks several possibilities for edging and trimming each board to determine if the grade can be increased. If so, it determines whether the value of the board is also increased based on the current market prices. Based on these measures, the program makes a determination on how the board should be edged and trimmed. Currently, the program is capable of considering six grades: FAS, Selects, # 1 Common, #2 Common, #3 Common, and Below Grade.
