Metodologia para avaliação do grau de sustentabilidade utilizando a lógica fuzzy: aplicação na indústria madeireira

Abstract

The economic needs of industries as well as the necessity of preservation of the environment require a development of its activities in a way that is environmentally responsible and, consequently, with the proper use of natural resources. The economy of the state of Pará is based on agriculture, livestock and vegetable and mineral extraction being the last one represented, mainly by wood. Certainly, it will contribute to the sustainable use of forest resources, an assessment that quantifies the subsystems environmental, economic and social, that are the basis of sustainability. Studying the segment of improvement and exportation of wood it was used fuzzy logic in a proposed methodology for determining the degree of sustainability that, in this study, may vary on a scale from 0 to 10, quantifying not only the condition of sustainability itself, but also indicating which subsystems or components need to be improved. The determination of public policy for the forestry sector can be performed using the same methodology, since that the necessary legal adjustments are made.
