基于案例推理(Case-BasedReasoning)作为一种重要的推理方法,近年来逐渐得到人们的重视。这一方法十分适用于非结构化问题的求解。本文针对基于实例推理的特点和群体决策的非结构化特点,在讨论基于案例推理方法的基础上提出了其对群体决策进行支持的结构框架和过程框架,并介绍了应用这一理论的优点。最后,提出了部分需要进一步发展和研究的问题。 Based on Case-Based Reasoning (Case-BasedReasoning) as an important reasoning method, in recent years gradually get people’s attention. This method is very suitable for solving unstructured problems. In this paper, based on the characteristics of case-based reasoning and the unstructured characteristics of group decision-making, this paper proposes a structural framework and a process framework to support group decision-making based on case-based reasoning. The advantages of applying this theory are also introduced. Finally, we put forward some questions that need further development and research.
