The optimization of calibration of the computer model describing the flows in the water distribution network; Study of the example

摘要

The paper describes the issues of optimization of calculations performed during the calibration of a computer model describing the flow in the water distribution network. Optimization concerns the efficiency of these calculations which means not only the volume and speed of calculations, but above all, the optimal use of the measurements made during calibration to obtain the best, i.e. the most real value of the searched parameters/characteristics of the system components. The paper includes a short introduction which orders the range of methods of calibration and the area of calculation methods used in this class of issues, and then the description of an example where in the calibration process was used a computational tool called EPANET Calibrator developed by scientists – engineers of cooperating Brazilian universities. This tool is based on genetic...algorithm.
