Research on Architecture of Decision Support System

This paper propose a new architecture of decision support system which integrates data warehouse, knowledge warehouse and model warehouse as the infrastructure of the decision support system. Its features, the new concept of model warehouse and the critical technologies of realization are described in details. The architecture proposed here effectively solves difference between models and objects, simplifies the tasks of acquisition and coding of models, it enhances the effectiveness and intelligence of the decision making and improves efficiency.
