Análise da produtividade em fábricas de painéis compensados plastificados

Abstract

The direct and indirect interaction of the forest sector with other industrial segments such as segments of the pulp and paper, furniture and construction industries, favored the strengthening of the timber industry and its economic and social development, providing significant employment generation and being helpful to the regional development. The plywood industries in the period from 2002 to 2007, were benefited by the foreign market, holding 90% of its production for this purpose, favored by the international price and exchange rates. In 2008, due to the global financial crisis that had been occurring in recent years which led to the fall in the price of exports and the emergence of economic barriers arose in relation to a company restructuring process productively, they returned to the domestic market, with the strengthening of production lines for new products such as laminated plywood. This study focuses on assessing the impact of the thickness of laminated plywood on the productive efficiency of enterprises of plywood. This analysis was performed in the companies of the Central Eastern meso, in Parana state. We collected data on productivity in the main process machinery for the plywood and conducted two experiments with experimental design of randomized blocks with subplots, evaluating time of manufacture of wooden blade and time spent on activity that occurred immediately before and after manufacturing. Based on work Borelli Pölzl (2002) indices were generated, which regulate the production efficiency of the companies sampled. The companies surveyed were working with a production shift, maintaining an average 60% idle and 20% losses in the production process. The average productivity of employees was 13 m3/ month, and lower productivity offset was analyzed for the 10 mm thick, is growing as we increased the value of the thickness. It was confirmed in this study the lower productivity of the press, independent of the thickness of the plywood, the signs of internal company production problems affecting its production efficiency, productivity not related to the type of machine as well as increased productivity corresponding to the increase the thickness of laminated plywood. As the magnitude of the productivity achieved in the module manufacturing production lines, the situation is technically worrying, showing low standardization of productive procedures.
