Desempenho operacional de uma serraria de pequeno porte do Município de Alegre, Espírito Santo, Brasil

Abstract

Sawmills are the most important wood industries in the Southern of the Espírito Santo State. The aim of this research was to analyze the operational performance of a small sawmill in Alegre, Espírito Santo state, Brazil, which process Eucalyptus sp. logs. The analysis was based on the study of lumber yield, operational efficiency and work delay ratio. The average lumber yield was 53.6% ranked as good for a small log hardwood sawmill, according to the literature. The average operational efficiency was 2.77 m3/worker/shift, and was ranked as low, even for small Brazilian sawmills, due to not classified logs, layout inadequacies, machinery bad conservation and low automation level. The average productive work was 69.6% and did not achieve the minimum rank of 75% suggested by the literature, because of the referred problems, and other ones. In general, for such sawmill the operational situation was considered poor, but it has potential to be improved.
