The Research On Open Decision Support System

Decision Support System is a computer-assisted application systems designed to provide decision support with for enterprise, in which the new data warehouse-based decision support system is to be the most thorough and most extensive research. But with the acceleration of global economic integration process, making the data more complex, enterprises require the speed of data feedback to be improved rapidly in decision-making in the business, decision support systems are gradually exposed in the anti-life-cycle issues, and the status has also been seriously challenged. How to deal with the issue of diverse and heterogeneous data sources, and manage meta-data effectively, has become a hot in the research of Decision Support System.Based on an overview of decision-making support system firstly, this paper analyses the way to make up the gap in the current decision support system, and ultimately determines the parts to a unified interface, and manage decision-making support system openly. And then researches the new decision support system conducted in-depth, describes some meta-data model and analysis model that could be implemented openly, proposes the basic framework of, based on the new data warehouse, decision support systems open management, the principal tasks are as following: (1)Defines the meaning of an open management, and analysis the advantage using Web technology to build models .(2)Based on the new decision support system model , we use frame design of the hierarchical structure, to design hierarchically for the model of open decision support platform and emphasize the relevant functional modules and its network topology.(3)Introduces the methods to achieve all levels of the corresponding interface of the model and the key technologies of these Web foregrounding of interfaces.(4)On the basis of the model, gives examples of a decision support system - the design and implementation of the collection of coal Sustainable Development Fund decision support system, and the final experimental results show that the proposed decision support system platform can be a good solution to the current decision support system's shortcomings, and has a certain value.
