PURPOSE: A system for analyzing the water supply pipe network based on the GIS(Geographic Information System) is provided to improve the efficiency of the water supply management by calculating the water supply quantity loaded on each pipe. CONSTITUTION: The system comprises a water supply pipe network DB(10), a pipe network management system(20), and a pipe network analysis system(30). The water supply pipe network DB, a basic data for operating the water supply management system, is largely divided into a figure DB and an attribute DB. The pipe network management system has the function of grasping the location and resource of the water supply facilities, of outputting a drawing from the water supply pipe network DB. The pipe network analysis system calculates discharge, fluid pressure, leakage quantity, and so on, which are loaded on each water supply pipe. |
