Research And Development Of Comprehensive Evaluation Decision Support System

Comprehensive evaluation is an important branch of the systems engineering.With the complexity of the comprehenxive evaluation object and the difficulty of the data-processing,the support of the comprehensive evaluation is critical.Decision Support System(DSS) is a computer system with man-machine conversation.It develops in the foundation of MIS and based on Model and Database,which has become the hotspot of researching in information domain.In the foundation of the study on the theory of DSS,and according to the characteristics of the comprehensive evaluation,the Decision Support System for comprehensive evaluation with a strong versatility is constructed in this paper.The Visual C++6.0 and Microsoft SQL Server 2000 are used in programming to realizing its main function.On this basis,the decision model including AHP method,grey relation and rough set are analyzed and researched in depth.As the application example,the system realizes the comprehensive evaluation of the various poly-generation projects.The system achives the good application results,and satisfy the expected requirements of the comprehensive evaluation.
