The Value Versus Volume Yield Problem for Live-Sawn Hardwood Sawlogs

The potential conflict between value and volume maximization in sawing hardwood sawlogs by the live sawing method was analyzed. Twenty-four digitally described red oak sawlogs were sawn at the log orientation of highest value yield. Five opening face sawlines were iteratively placed in the sawlog at 1/4inch intervals and lumber grades, volumes, and values from completely sawing the log at each opening face position were determined. Volumes were computed for several sawing positions of interest: maximum and minimum volume, minimum opening position, mean volume, and centered solution. Dollar values and distances from minimum opening position were also determined for these sawing positions of interest. Statistical comparisons of these variables showed that the conflict between value and volume yield was significant. A potential average loss of $2 per sawlog was indicated if volume yield was maximized at the expense of value yield. Results also indicated that a precise knowledge of internal defect location is appar
