The Integrated Application Of Network Analyst On Water Supply System In Shenyang City

Water is indispensable to human survival. In China, water shortage is highly serious and the quantity per capita is only a quarter of the world average. Water resource scarcity has been one of the key factors retarding the economic growth and building of a well-off society in an all-round way. In rencent years, The water supply industry in our country has developed greatly .But at the same time,so many questions in water supply networks to be solved. With the development of computer technology and management science, providing decision support for water supply optimal control and applying DSS in the water service field were the direction of municipal water service management. GIS can analyses the accidents of the water supply network and assists the administrators to deal with the mishap, which improves the managing level and the efficiency of unexpected things.The thesis is based on the above-mentioned problems, the main work are:First, studied and discussed the application of GIS in different fields carefully. Generalized the features of Water supply industry.All water and its ancillary facilities,and transport network,are the objects of GIS studying.Second, had a comprehensive study on GIS network analyst, including: the types of networks and its application fields,the structure of network data, the topology of elements,and connectivity in elemwnts.The focus is solving the shortest path,which is the key issues of network analyst.Finally, introduce the process of building two types network modles combination of practical problems based on the water supply data of Shenyang City. And then, analyse the problems by Find Disconnected,Find Loops,Finding a best route,Findind a service area etc.
