Using ELECTRE TRI to support maintenance of water distribution networks

problems encountered in the context of the maintenance management of water supply are evidenced by the lack of decision support models which gives a manager overview of the system. this paper, therefore, develops a model that uses, in its framework, the multicriteria outranking method electre tri. the objective is to sort the areas of water flow measurement of a water distribution network, by priority of maintenance, with data collected from an automated system of abnormalities detection. this sorting is designed to support maintenance decisions in terms of the measure more appropriate to be applied per region. to illustrate the proposed model, an application was performed in a city with 100 thousand water connections. with this model it becomes possible to improve the allocation of maintenance measures for regions and mainly to improve the operation of the distribution network.
