Spatial Aided Decision-making System for E-Government

1.1 basic concepts of Spatial Decision-making System Geographical Information System (GIS) is a new subject which rose in the 1960s, and is combined with computer science and geographic information science, and is also a technology system, it analyzes and manages geographic data contains spatial information using system engineering and information science theory under the support of software and hardware, and meets the need of planning, management, decision-making and researches. Decision Support System (DSS) generated in the 1970s, it is added to model base and management system based on Management Information System (MIS), is a computer system aiming at doing decision-making, and it provides decision support environment of analysis, model construction, decision-making simulation, decision evaluation for managers. With the development of its support scientific theory, DSS not only absorbs expert systems, fuzzy logic, neural networks, genetic algorithms, rough set techniques, etc, but also uses method base and its management system, knowledge base and management system to support intelligent decision-making. Spatial Aided Decision-making System consists of spatial decision support, a number of interdependence and interaction elements of spatial databases. It is an organic whole for spatial data processing, analysis and decision-making. It is a really new information system on the basis of the combination of conventional decision support system and geographic information system. It transforms spatial data, extracts facts and relations which hides in the spatial data and expresses these using forms of graphics, tables, character, provide scientific and reasonable decision-making support for all kinds of applications in the real-world finally. In order to adapt to the needs of information technology and enhance the level of administrative efficiency and decision-making, then realize optimization restructuring for government organizational structure and workflow, establish the government and the public electronic interactive channels, at last to achieve the development of national economic and social information, the government manage administrative departments use modern information technology roundly which is a new mode of management and 22
