Research Of Distributed Cooperative Decision System Based On Whiteboard

With computer technology development, market competition intensifies and the development of the information society needs, the traditional Decision Support Systems, which cannot adapt to the current decision-making needs. More and more research makes clear that decision support system couldn't localization with single database, simple person's collection and individual experience to decision. Collect decision information from a great deal of originality data, history information and plenty communion among the person demand that existing decision support system need more improvement and more optimize. This demand requires on-line services, and involves a large number of data to achieve decision-making.First, the article give a brief introduction of decision support systems and computer-supported cooperation work, decision-making algorithms research and development, and proffer a new type of concept — Distributed Cooperative Decision System Based on Whiteboard and built the system and the models. New decision support system in the traditional decision support systems based on the merits of other decision support systems and user require and technological developments and established new decision support system. The full use of decision support systems can be applied to a variety of computer network distributed features of the computer-supported collaborative work with the characteristics, and enhance the interface based on Whiteboard, so that users in the use of the system more convenient and flexible. This centralized control methods used to control and operation the object of whiteboard to avoid user conflicts, double-token algorithms used to control user voice to speak, so that users communion more naturally. In the decision-making algorithm applications, using a combination of two algorithms. Vague preferences algorithms based on individual schemes for policy makers to facilitate the selection of the scheme;Based on the uncertain value of attributes described in thealgorithm language of the scheme is not limited to the overall decision-making preferences. In the article, the establishment of the system's architecture and the various modules and systems function of a detailed description.The Distributed Cooperative Decision System Based on Whiteboard combined with the merits of decision support systems and advantages of group decision support system, making full use of its distributed features of the decision support system can be adapted to advance network technology development.
