The application of decision support system based on layer model method

Layer model method is a new development method of Decision Support System (DSS). Layer model method is one of multi-layer model integration methods based on General System Theory (GST). It uses layer division structure and looks on the multi-layer model as conceptual model. It divides DSS into four layers: application layer, task layer, function layer and physical layer. Based on this, this paper describes the background of Layer model method, and then illuminates its research thought, and clarifies the design and development of a financial Decision Support System in detail. At the application layer, we turn the decision problems into models and put up with problem solving strategies. At the task layer, we build data models and PRF, and analyze the solving procedure of system. At last, we evaluate the effects of this financial DSS. As a kind of general DSS generator and a new development method, layer model method has good theoretic value and practicability.
