The aim of this paper is to contribute for the improvement of the Portuguese performance assessment system,
through the development and application of a complementary methodology to define sectoral and global indices of sanitation service performance in order to evaluate the sustainability of a given wastewater utility. This methodology allows a truly quantitative evaluation in which each performance indicator represents a criterion to be considered and judiciously weighted. The sectoralindices are calculated as a weighted linear combination of the normalized scores of each performance indicator, which is one of the most common aggregation procedures available in the context of multicriteria evaluation. The criteria normalization process essentially based on fuzzy sets defined for each indicator. A sensitivity analysis of indices values to different weighting methods was also performed.
The Centre for Territory, Environment and Construction (CTAC) is a research unit of the School of Engineering of University of Minho (UMinho), recognised by the “FCT – Fundação para a Ciência e Tecnologia” (Foundation for Science and Technology), associated to the Department of Civil Engineering (DEC), with whom it shares resources and namely human resources.
Currently CTAC aggregates 25 researchers holding a PhD of which 20 are faculty professors of the Civil Engineering Department. Read more
