Abstract
Informatization has been becoming an effective and efficient measure for urban infrastructure management to heighten its effect. This paper defines urban infrastructure management and describes the framework of its informatization in the viewpoint of life cycle. On the basis of above definition and description, this paper presents the model of the informatization for urban infrastructure planning, construction, and management based on Web GIS and DSS, which involves the informatization for the infrastructure management of energy sources system, water resources system, communications system, posts and telecommunications system, environment system, and disaster-preventing system. Then the functions of the model are analyzed. Finally, as an example, informatization for the management of urban wastewater treatment infrastructure is analyzed to discuss the functions of above model. The applications of the model would heighten the management level of urban infrastructure, which would reduce the cost of urban infrastructure construction and maintenance, as well as improve its service level.
