Abstract
Numerical simulation is used to analyse machine strength
grading of sawn timber. Starting from correlations
between grade determining properties and measured grading
properties, sets of values of properties are generated
and machine grading simulated including the determination
of settings and application of the settings to another
generated sample.
Results are obtained concerning the statistical effect of
sample size to the accuracy of grading and yield to
various grades. Also the lower tail of strength
distribution of various grades was analysed with the
conclusion that the highest grade has relatively better
strength distribution than the lower grades.
