Modelagem fuzzy para avaliação de desempenho ambiental do gerenciamento de resíduos sólidos industriais

Abstract

This Thesis develops an instrument for evaluating environmental performance in management of industrial solid waste. The practices verification consider the industrial product life-cycle through indicators and indices based on the National Policy on Solid Waste parameters and related concepts such as reverse logistics, Cleaner Production and Ecodesign, and standards like ISO 14000 series such as environmental management systems, integrating environmental aspects in product design and development, environmental labels and Environmental Performance Evaluation. The central Thesis’ aim, that was to develop an environmental evaluating model, contains this panorama, which calls on a fuzzy modeling tool to assist organizations in making decisions. Two methodological research groups covered the dicussions and the instrument construction called Environmental Performance Index of Industrial Solid Waste Management (IDEA PNRS+L): qualitative and quantitative. This fuzzy modeling is composed of 26 indicators and 23 index, conceived in top- down soft decision tree form. The index calculation - composed of fuzzy rules, variables and their inferences - included a group of specialists respondents view, through a survey, to adjust the variables influence degrees of each index. In the simulations, testing and application of the created instrument in an industry to assess their potential, IDEA PNRS+L was sensitive even to small variations of the input data, plausible and reliable, to reproduce the behavior established in the initial configuration. Concluding, the fundamental parameters that formed the theoretical framework were quite comprehensive and allowed the construction of Environmental Performance Evaluation called IDEA PNRS+L, appropriated for industrial arbitration. Simultaneously, the rules, government initiatives concepts and accurated environmentally professional attitudes supported by avant-garde products and services concepts were recuperated.
