Optimisation of timber harvesting work of Logset 5H medium power harvester

摘要

This article analyses field measurements of harvestor operation activities with the aim to search for optimum production conditions of the machine from the point of fuel consumption and operation efficiency. All applied measurement and calculation approaches are based on the methodology for the evaluation of the natural principle of minimax. This principle is one of the most complex decision-making principles in deploying technologies in these activities with minimum energy costs for machine operation, and with regard to the economy of operating these techniques. The measured and calculated values revealed that considering the stated criteria the optimum conditions of the tested machine occurred when a harvested stem had a volume between 0.2 and 0.4 m3.
