Master Thesis represents comparison between two different firewood production chains MCK (chainsaw - splitter- circular saw) and MRCA (chainsaw - cut-split processor) for production of short (25 cm) and long (33 cm) firewood in two organizational forms of work – with extra worker (I + 1) and without one (I + 0). Our objective was to find out differences between systems in productivity level, noise exposure of worker and production cost of work. The recordings took place at home ground locations. We prepared by quantity and diameter structure two similar piles of timber (Fagus Sylvatica L.), which were measured and marked in advance. We found out 34 – 50 % higher production rate by MRCA system than in MCK system, also the production was higher while producing longer firewood. The noise exposure level was higher at MCK system (LCpeak = 135,8 dB(C), LAeq.kor =99,2 dB(A)) and lower at MRCA system (LCpeak = 128,46 dB(C) ter LAeq.kor = 92,69 dB(A)). The worker is most burdened while working with chainsaw, circular saw and cut-split processor. The production cost of work was higher while operating with MCK system (16,0-85,6 €/volume meter), on the other hand MRCA system had lower production cost (6,5-42 €/volume meter). Average firewood production cost, working with MRCA system, was between 10 and 15,1 €/volume meter and between 30,4 and 36,8 €/volume meter while working on MCK system.
