Abstract

The aim of the research was to create a mathematical dependence to justify the labor costs of moving a fallen tree by harvester to the zone of its bucking, depending on the variety of values of natural factors characterizing the operation of the harvester during the partial cut of the forest. For this research, the computer simulation model of the technological process of the forest harvester was created. Production experiments were carried out to test the model. The computer experiment was implemented on the model, and regression dependence was obtained. The results of this study showed that the relationship between the residual density of plantings and the execution time of the moving operations using regression dependence. The multiple coefficients of determination of the nonlinear model was 0.845. This value indicates that the change in the average time of moving a fallen tree to the zone of its bucking depends on changes in the factors included in the regression model, and this dependence is not accidental. The results can be used by research organizations when planning the production process of logging operations.
