dc.description.abstract | Asset management in hydraulic infrastructures aims for the long-term sustainability of water distribution and
wastewater networks. Strategic maintenance planning has thus been deeply analyzed in the literature for indi vidual water and sewer pipes. However, water utilities do not plan and perform replacement activities on in dividual elements, but rather on coherent aggregations of neighboring pipes. We have developed a decision
support system (DSS) to help water utilities design intervention programs for hydraulic infrastructures. It in tegrates a two-stage algorithm that groups water supply and sewer pipes into practical and efficient replacement
works, based upon their proximity and their priority of renewal. A multi-objective genetic algorithm optimizes
the work programs configurations while integrating the water company’s strategic policy into an innovative
multi-objective function. We have applied our methodology to a large water company in Spain and illustrated
this application with a sensitivity analysis to determine how the company’s strategic criteria influences the
resulting work configurations. | es |
