Abstract.<\/em><\/strong> <\/em>Modelling of optimal hydraulic pipeline for regional and interregional water supply systems is highly relevant because of water scarcity in some parts of Russia. For a multi-extreme optimization problem to which this problem relates a local extremum is not sufficient and an absolute extremum is not possible since it would take a massive amount of computing power to solve. The purpose of the research is to develop a method, algorithms and software system for computer modelling of large branched water pipeline systems with higher-order optimality. The basis of the method is to divide the synthesis problem with flux and potential variables (Kirchhoff’s circuit) into two phases; it allows us to significantly reduce the computation time and resource requirements. The first phase determines the network structure while the second one identifies values of hydraulic parameters. The proposed methodology, algorithm and software are designed for computer modelling of branched water pipelines systems of regional and interregional water supply as well as for large-scale irrigation systems.<\/p>\n\n\n\n
