Abstract
The "Simplified grading selection method" (Szász és Burján 1975) developed decades ago by the Forest Research Institute (FRI) and founded upon an earlier range of selection methods and evaluations of the diameter at breast height for logging became obsolete and necessitated updating and modernization. This was adjusted to the prevailing current logging data in order to make valuable original data useful and useable for the design and evaluation of current logging practices. We developed a simple solution for this: the so-called two-step proportioning method. However, the use of FRI tables requires the need to know the quality of tree stands as well. For this purpose, we utilized the trunk rating system in the Forest Planning Guide, making some adjustments to suit the task at hand. The resulting selection structure multiplied by current average prices determined average revenue. Our method proved suitable for different levels of aggregation including national, forest company, and forest subcompartment levels. The process can be considered as a „sales-centric quality classification” of stands. To calculate the overhead cost of logging operations, we utilized the suitable portion of the developed cutting organizational plan (Szasz, 1979), and named the modified version the "Sopron series analysis method".
