Análise do rendimento e eficiência na produção de dormentes de Eucalyptus grandis Hill ex Maiden em serraria de pequeno porte

Abstract

Many industries of lumber in Brazil still have undeveloped and low productivity structure, and its survival in the market depends largely technical efficiency of production processes. It is essential to analyze all stages of the production process which is characterized in the material balance and assessing the performance of the industry. Studies on yield and efficiency in the production of sleepers are scarce. Considering that this is a production process that started many years ago, it is critical that research be conducted in this area, which can bring very important for the timber industry results, mitigating the generation of waste and increasing yield and efficiency thereof. Analyzed before the results can be said that the diameter class of 25 - 35 cm is the most suitable for the production of sleepers compared with other classes analyzed. The examination of flatness and taper factors for production of railway sleepers for this study was not significant in explaining yield diameter classes. Overall, the increase in diameter of the logs has resulted in increased operational efficiency. Thus, the mill was classified as satisfactory performance, based onefficiency and throughout the productive work.
