This subject research work affiliates the national natural science item, which is " study on the basis of complicated problem decision support mode that structure can calculate ".The research work of the dissertation is divided into two sections: the first section is the research on the representation method of complex decision problems, and the main works in the section includes analyzing the characteristic of domain information which belong to complex decision problems, analyzing the importance, difficulty and solving of the representation method of complex decision problems and so on; the second section is research on analyzing complex decision problems using analogy reasoning quantitative method, and the main work of this section includes analyzing the information structure of the experts, analyzing the thought of the expert using to solve the complex problems, analyzing the model using to denote the complex problem, constructing the list which store the field knowledge, analyzing the analogy reasoning of cases and so on.The content of every chapter in the dissertation as follows:Firstly, this paper discusses the existent problem and the defect of the conventional decision support systems which face to model in the present research work of decision support system, puts forward a DSS mode facing to problem, makes certain the purpose and the significance of research work in the dissertation and summarizes the other research works correlative with the dissertation.Secondly, this paper presents the theoretical foundation and the realized technology of case-based reasoning method, sums up the merits and defects of this method.Thirdly, this paper analyzes the importance of expressing the complex decision problems from three respects: understanding practical problem, collecting and reoccupying of the case, and being convenient to solve complex problem. Aimed at the characteristic of the domain knowledge of the complicated problem, it discusses the difficult point and focal point in expressing the...
