A decision support method for environmental impact assessment using a fuzzy logic approach

This paper presents a decision support method for environmental impact assessment, using a fuzzy logic computational approach. It aims at offering stakeholders a way to operate fuzzy and crisp variables and make inferences from resultant values of the systemic indicator as well as environmental, cultural, social and economic thematic indicators. The method was tested in the Environmental Protection Area of Anhatomirim (Santa Catarina state, Brazil) forecasting alternative future scenarios for the adaptation of a highway route and paving project.
