spectively. The first post-hoc test with Kruskal-Wallis revealed that the average efficiency of sawnwood production decreased significantly with time. The second post-hoc test with Mann-Whitney showed that the average technical efficiency in different production scale varied significantly, however, the power capacity and wood species had no effects on technical efficiency.
