The Research On Decision Support System Of Haidian Zone

HDYDSS is made up of six subsystems including Leader's Querying system, Economy Inspecting system, Economy Judging system, Economy Alerting system, Economy Forecasting system and Public Management system, all of which effectively organize the data of Haidian Zone and make full use of them. Analysts can build target system to analyze the data and make analysis reports; Leaders and decision-makers can query analysis reports and see analysis results; Administrators can authorize different functions to different users through a fine-grained access control system. HDYDSS gives strong support for leaders'decisions of Haidian Zone and is highly praised by users.At first, this paper introduces related knowledge and recent research about Decision Support System. Then it discusses the demands, design and implementation of HDYDSS. After that, it analyzes the performance bottlenecks, software structure and code styles of current system, gives some methods to solve these problems such as adding cache to current system and making performance comparison. Finally, this paper discusses the model and model management system, gives prototype codes of Object-Oriented description of them and how to describe the relationship among composite models, atom models and methods, which gives directions for consummating Economy Forecasting system.
