Abstract
The Log Recovery Analysis Tool (LORCAT) is a simulation tool that allows users to examine the impact of changes in the hardwood log-sawing process on sawn volume, grade recovery, and profit. LORCAT was designed to be simple to use and requires a minimum of user data entry. While the results of LORCAT have been informally compared to sawmill results by users, no formal validation of results has yet been performed. This study compared LORCAT’s simulated recovery results to that of an actual sawmill. For the 42 hardwood log samples we examined, we found no significant statistical difference in the total sawn volume produced. However, significant differences were found with the number of boards produced, which resulted from differences in the accuracy of targeting the opening-face board size.
期刊介绍：
Forest Products Journal (FPJ) is the source of information for industry leaders, researchers, teachers, students, and everyone interested in today''s forest products industry.
The Forest Products Journal is well respected for publishing high-quality peer-reviewed technical research findings at the applied or practical level that reflect the current state of wood science and technology. Articles suitable as Technical Notes are brief notes (generally 1,200 words or less) that describe new or improved equipment or techniques; report on findings produced as by-products of major studies; or outline progress to date on long-term projects.
