RESUMO

The water supply quality is very important to the healthy of urban nucleus populations around the world. This is the reason why many researches focus on such theme. Besides this, recent terrorist attacks occurred in USA and Europe, have incited the old apprehension related to possible deliberate intrusions of contaminants into the water supply networks, making evident the importance of the effective vigilance of such systems. This work investigates the optimal monitoring network for detection of deliberate intrusions of pollutes and/or contaminants at concentrations and/or quantities enough for propagation inside the networks, on the point of view of multiple objectives. The method here proposed represents an extension to earlier proposals and is demonstrated with the support of networks from literature. Based on the concept of auxiliary network proposed by Kessler et al. (1998), a multiobjective genetic algorithm is used in order to consider the levels of service in terms of the consumed volume, time period and length of the network reached before detection. Pollution matrixes are built for the levels of service considered and the multiobjective genetic algorithm SPEA applied in the identification of the non-dominated solutions, according to the Paretto optimality concept. The results demonstrate the potential of the method in the identification of such solutions
