In some domain expert’s decision-making is intelligent output by comprehensive analysis and reasoning for the numerous decision-making factors,constraints and the goal in their domain,it is the concentrated expression of domain knowledge.Be aimed at field knowledge induction;sum up the exploration with systematization method,the two stages case-based reasoning(CBR) technology on the basis of the expert decision cased is present.The main idea,according to the characteristic of problem,analysis and decision process of field expert is carried out case-reasoning by two steps,and the field knowledge can be classified,induction and accumulated from different angles by multi case libraries.This technology includes two aspects,first,through two state case-based reasoning mechanisms to achieve area of decision-making process simulation;second,the CBR service in two more cases of library design process.First,two stage case-based reasoning mechanism,the first stage case-based reasoning to analyze the main level,clear nature of the problem,type,degree and character as the main content;the second stage case reasoning takes first order case reasoning result as basis then,the case reasoning,gives to making policy holding out being that purpose is in progress to out a decision-making suggestion once again.Secondly,in many cases the design of the library,to serve two-stage case-based reasoning process,the design of the four case libraries:First, property type case library,is a static case base can be modified,the effect is to performance differences between actual case and plan case of the qualitative distinction,indicate difference type attribute;Second, hierarchic quantization case library,is a static case base can be modified,the effect is to performance differences between actual case and plan case the quantitative distinction between the scope,indicate degree, size that the type issues in some difference etc.Three are that decision-making supports case library,is a static case base can be modified,the effect is similar enumeration all possible decision-makings content, indicate the decision-making that field expert possibility carries out;Four are decision match case library,is a self-study and dynamic case library,the effect is the library recording history decision-making case,is used to gain the decision-making scheme specifically for current reality achievement case is similar,to provide the support making policy,to learn composing in reply the case accumulating the new decision-making at the same time.The method is based on real business needs for research and development obtained after the conclusion,the paper shows through examples of the technology industry has a good adaptability,practicality and effectiveness.
In some domain expert’s decision-making is intelligent output by comprehensive analysis and reasoning for the numerous decision-making factors, constraints and the goal in their domain, it is the concentrated expression of domain knowledge.Be aimed at field knowledge induction; sum up the exploration with systematization method, the two stages case-based reasoning (CBR) technology on the basis of the expert decision-cased is present. The main idea, according to the characteristic of problem, analysis and decision process of field expert is carried out case- reasoning by two steps, and the field knowledge can be classified, induction and accumulated from different angles by multi case libraries. This technology includes two aspects, first, through two state case-based reasoning mechanisms to achieve area of decision-making process simulation; second, the CBR service in two more cases of library design process. First, two stage case-based reasoning mechanism, the first stage case-based reasoning to analyze the main level, clear nature of the problem, type, degree and character as the main content; the second stage case reasoning takes first order case reasoning result as basis then, the case reasoning, gives to making policy holding out being that purpose is in progress to out a decision-making suggestion once again. Secondarily, in many cases the design of the library, to serve two-stage case-based reasoning process, the design of the four case libraries: First, property type case library, is a static case base can be modified, the effect is to performance differences between actual case and plan case of the qualitative distinction, ie, difference type attribute; Second, hierarchic quantization case library, is a static case base can be modified, the effect is to performance differences between actual case and plan case the quantitative distinction between the scope, indicate degree, size that the type of issues in some difference etc. Three are that decision-making supports case library, is a static casebase can be modified, the effect is similar enumeration all possible decision-makings content, indicate that the decision-making that field was originally carried out; four are decision-making case library, is a self-study and dynamic case library, the effect is the library recording history decision-making case, is used to gain the decision-making scheme specifically for current reality achievement case is, to provide the support making policy, to learn composing in reply the case accumulating the new decision-making at the same time The method is based on real business needs for research and development obtained after the conclusion, the paper shows through examples of the technology industry has a good adaptability, practicality and effectiveness.
