EnglishThe selection of the most effective course of action for pipe rehabilitation is crucial to avoid the uncontrolled deterioration of water distribution systems (WDS). Moreover, it provides a rare opportunity to modify some elements of the existing infrastructure in order to meet the present service requirements. For instance, a rehabilitation plan could be aimed at simultaneously improving system reliability, pressure levels and/or leakage reduction. In this work WDS rehabilitation is formulated as a multi-objective optimization problem where decision variables for each pipe are "do-nothing" or "replace" by selecting from a set of commercial pipe diameters. It is shown that the solutions returned by a multi-objective genetic algorithm (MOGA) in such a complex decision scenario although good, could not be easily used to support decision making. A prioritization strategy is developed and presented which is based on MOGA solutions and provides an effective tool for both analysts and decision makers.
