Study Of Group Decision Support System Model Library

This paper narrates Decision Support System(DSS) and Group Decision Support System(GDSS) and summarizes type, function, structure, relation, evaluation and major research of GDSS. Model Database is the core of GDSS, so we should study Model Database and Model Database management in detail. Aiming at the special model, several works are studied by releality, such as analysis of model, function of model and solution of model.In this paper, the model of diversified investment management is founded on the basis of the analysis of basic principle and the group decision process and the solution of scheme selection are given. For model according with the reality and using in enterprise, model should be simplified for supporting the decision of enterprise. There, we consider the factor of risk has the investment of enterprise and we try to quantify it. Then the problem of diversified goal can be translated into the hierarchical goal programming equivalently. Last, by utilizing technology of ASP and ADO, interface of BBS is designed and the group decision process of model is achieved by writing program. So the research of group decision support system has innovation and development.
