Analysis of the volume differences on primary registration of raw timber by production sites and measurement principle

The main aim of this thesis was to analyze the differences in the volume of first intake of raw timber, according to production sites and measurement principle. There were compared the volumes of primary documents of income and evidence produced timber called summary for growth - assortments and volumes of prin-ted output, based on a production-registration software harvester. In the data pro-cessing was discovered major factor in emergence of differences, for which had to be revised methodology for data evaluation. Due to production indiscipline of the forwarders operator was not possible to assess the volume differences according to the Forest stand groups, but had to be chosen method of data assessment ac-cording to production units. Another factor contributing to the emergence of vo-lume differences was harvester operator. The operator didn´t carry out regular kalibrati-on of harvester measuring system and during entering into production-registration software showed substantial insubordination. In operation, authorities also failed production control of all participants of comprehensive contract. It was especially control of technological procedures. All measured values showed significant differences in the volume. Condition of LCR, claiming differences +- 2% and it meets only 11% of them. There was evaluated the total differences, followed by trees and various assortments. The resulting differences could influence conversi-on coefficient, which was same for all of the assortments of coniferous trees, which certainly doesn´t reflect their quality
