Portfolio management of sanitation projects in the PCJ Basin Committees: multicriteria method for hierarchization

High costs and limited financial resources make it essential to prioritize sanitation projects. Multicriteria methods, for individual or group decisions, constitute modern tools to rank project portfolios. Currently, there are many methods available in the scientific and technical literature. In Brazil, the Hydrographic Basin committees constitute the institution for decentralized decisions to manage projects portfolios. This article proposes a multicriteria model of decision support for prioritizing a portfolio of sanitation projects within the scope of a basin committee. As a case study, a portfolio of 14 projects is used, which is the subject of a public notice for the application of financial resources from FEHIDRO and/or collected by charging raw water in the Piracicaba, Capivari and Jundiai (PCJ) basins. The method Promethee II was used with the graphic extension GAZA. The model provided a detailed analysis of the potentialities of the alternatives. It was possible to visualize not only the ordering, but also all the overcoming properties of each alternative by the matrices and the graphs presented.
