Study on the graded knowledge base of an intelligent decision support system

Decision support system (DSS) is a deep knowledges of management information system (MIS), which can be developed into intelligent DSS by introducing AI(artificial intelligence) into it. The graded knowledge bases is advantageous to knowledge combination and fully utilize. The deep KB(knowledge base)keeps atom-knowledge or macro-knowledge which can combine with reasoning machine together to accomplish intelligent decision by the way of usefulness of shallow knowledge of the combination of atom-knowledge or macro-knowledge. The shallow KB is divided into dynamic part and static own. To achieve steady shallow knowledge support and renewable shallow knowledge support. The data structure of deep knowledge base has the form of hypertext for the convenience of atom-knowledge and macro-knowledge and deep knowledge acquisition.
