Decision Support System Based On Information Grid

With the establishment of grid standard, the theories of grid has moved towards application. The grid and its application are stepping into a new period of quick development. Li Guojie, academician of Chinese Academy of Science, figures: Grid can be called the third generation of Internet technology. It has achieved entire connection of all kinds of resources on Internet. The information grid represents application of grid in information processing and sharing. Using available facility, criterion of agreement, web and database technology, the information grid offers a integrative intelligent information plat for users on which they can visit all kinds of information through a unique entrance. What's more, the information processing will be distributed, synergic and intelligent.Meanwhile, DSS has achieved great development in theoretical research, systematic exploiture and practical applications. However, its deficiency in theoretical frame and original technical flat leads to many problems such as serious "information island", stiff structure, bad modularization, short life circle, and so on. Luckily, information grid happens to solve these problems perfectly. So the joint of information grid and DSS will become the next focus when we study DSS model.This thesis solves following problems: First, makes a summary on grid technology and discusses about information grid which relates to information processing and information share; Second, discussed about DSS, including its sort, its foreground. etc; Third, analyzes problems in DSS research; Fourth, designs a DSS model based on information grid and analyzes about every single module of the model including its structure and how to carry out; Fifth, achieves information services of decision-making resources using moving Agent. And the services in turn can achieve a peer to peer monitor. Also, the services involve many technologies such as Mobile Agent, CA, LDAP agreement and IG Service and so on. Finally, gives a practical example to make a ulterior analysis about running flow of DSS based on information grid.
