Nova abordagem para a análise multiobjetivo final dos estudos de inventário hidrelétrico de bacias hidrográficas

Abstract

This thesis proposes a new approach for the final decision making of the River Basin Hydropower Inventory Studies to select the best alternative to explore the hydropower potential of the basin. This new approach quantifies and incorporates new criteria needed to exploit the hydropower potential still available in Brazil: the negative socio-environmental impact outside the basin and the environmental benefit due to the implementation of hydropower plants with a more sustainable bias. This new approach also proposes to change the current multicriteria method to select the best alternative (weighted sum), seeking to reduce the difficulty of defining the information required by the method. Three promising methods are proposed: VIP Analysis, ELECTRE III and ELECTRE IV. An application in a case study is performed considering the two new criteria and the three proposed multicriteria methods. At the end there is a discussion concerning the selection of the most appropriate multicriteria method for the final studies of Inventory Studies, taking into consideration the opinion of specialists/decision makers
