<p>PURPOSE:To perform hydraulic analysis at a high speed with a high precision by a small-sized computer by preserving data only for main pipes of the whole of a region as overall hydraulics data in a data base and using branch pipe data of the analysis object and overall hydraulic data to perform hydraulic analysis of main pipes and branch pipes in the object region. CONSTITUTION:At the time of hydraulic analysis of the water supply pipe network consisting of main pipes and branch pipes, data only for main pipes of the whole of the region is preserved as overall hydraulic data in a data base, and branch pipe data of the analysis object region and overall hydraulic data are used to perform hydraulics analysis of main pipes and branch pipes of the object region. That is, hydraulic analysis is performed with a small number of main pipes in all regions and branch pipes in the analysis object region.</p> |
