The optimal bucking system consists of the following modules: File, Run, View, and Help.
User input to the computer-based bucking system includes species, butt diameter, and the number of grade zones for each tree to be bucked.
Since tree-stem and bucking solution data are saved in the database, the system allows the user to view and print out the data for other uses.
The logger is an experienced crosscutter and has many years of experience on bucking operations with the logging company in the region.
[V.sub.ijkl] = the lth tree-stem of value or volume yield under the ith species group, the jth bucking method, and kth butt diameter class,
About 60 percent of bucking patterns generated by the computer were different from the patterns bucked manually.
The effects of three interactions among species group, butt diameter class, and bucking method were tested on gross value and volume yield of bucked logs per tree.
Although there was no significant statistical difference, the optimal computer-based bucking system resulted in a 13.8 percent increase in potential gross log value.
