Abstract

This article proposes the use of water quality indicators to evaluate water distribution companies employing a multicriteria analysis that encompasses the Grey theory and the TOPSIS method. The main benefit of the framework is the generation of a final comparative ranking, which may assist managers, regulatory agencies, investors, users, society, and providers themselves in visualizing the quality performance of the companies analyzed. The results of applying the proposed framework to Brazilian companies proved robust after a two-step sensitivity analysis, which involved varying weights and excluding criteria.
