The Research Of The Model Development Method In Decision Support System

Decision Support System is one kind of man-machine interaction system that helps decision-maker solve structured and half structured problems using various of data,information knowledge,especially the model technique. Model Base System is a core component of decision support system, is also the decisive factor in decision support system development. The good or bad of the model base system design will have a direct impact on decision-making analysis.However, to build model base system is still a challenging and complex task, mainly because the model base system with the enterprise business model changing, it is possible for model base system timely update the model to adapt the change of business. But until now, all methods do not consider the model base system as an integrated system to design. By the Platform Independent Model (PIM), Platform Specific Model (PSM), the code (CODE)-driven development model driven architecture (MDA) is in order to solve the distributed and heterogeneous systems integration issues raised by the next generation of solutions.This thesis describes a development framework of decision support system based on the MDA. By using UML profile models PIM and PSM of MBS respectively. Presenting a rule to describe PIM transforms to PSM by using relation language of QVT (Query/View/ Transformation). And implement this rule in the open-source tool-mediniQVT. Moreover, implements transformation from PSM to SQL under EMF (Eclipse Modeling Framework) which is presented by IBM. Thereby, to realize a model-driven development process based on the model. And apply this method on a DSS of an iron and steel enterprise. It indicates that the method in the paper increase the efficiency of system development compares to the traditional method. Therefore, makes the model having more normative, realizes the share between models. Meanwhile, it profits the reuse and maintain of model.
