Resumo
Increasing population united the behaviour of man carefree about the environmental
preservation has led to a scarcity of natural resources. A key resource for human
survival has been directly affected by these desmazelos, water. Based on this context
arises as a commitment to operational excellence of water supply systems, seeking
greater efficiency in the establishment of operational rules. To this end, the general
objective of this research is to develop a study of water distribution networks model
calibration, because it is believed to be the best technique for tracking this problem by
adjusting the physical parameters that have changed over time and dictate strategies.
This work aims to develop a technique based on the inverse of calibration using GAs as
a tool for optimization, using multiple goals: pressure and flow. The parameters
adjusted were roughness coefficients and coefficients of losses by leaks. To evaluate the
proposed methodology were employed two networks often used in literature. The first
network employed is a theoretical system proposed by Tucciarelli (1999) and was used
to evaluate the behavior of multiobjectives methods and their parameters. The second
network is located in Campo Grande (MS) has been studied by Cheung (2004) and
Soares et al. (2004). This example is a real system that had its data measured in situ and
presents all the complications inherent in the calibration real problems. The results were
very satisfactory, since the optimization multiobjective shown to be able to improve the
accuracy of the calibration of the model.
