Abstract

This paper is part of the Battle of the Water Calibration Networks (BWCN) organised during the 12th annual Water Distribution Systems Analysis conference (WDSA 2010) in Tucson, Arizona. The BWCN calibration problem is formulated and solved as a multiobjective optimisation problem with the objectives being the minimisation of different types of absolute relative errors. The implicit constraints are comprised of mass and energy balance equations written for the extended period simulation model of the analysed system and the five fire flow steady-state conditions. Calibration parameters are the grouped pipe roughness coefficients, two valve coefficients for one DMA, and a speed factor for one pump. Prior to calibration, the analysis of the pipe network topology has been performed. The hydraulic system results are spatially decomposed and simplified leading to substantial computational savings (without loss of accuracy) and enabling an easier analysis of results. The above calibration problem is solved using a multiobjective genetic algorithm. The results obtained on the BWCN case study demonstrate good agreement between the predicted and observed values.
