研讨是支持群体共同求解复杂决策问题的有效工具,其本质上是一种多人间的逻辑思辨与推理的过程.本文借鉴人工智能领域中的辩论理论,提出了一种基于辩论的群体研讨模型与决策方法.首先对比分析了一般研讨流程与辩论过程,揭示了群体研讨决策和辩论过程在机制和目的上的相似性;然后引入Dung的抽象辩论框架,建立了基于辩论的群体研讨系统框架,并探讨了论据状态的推理机制和论据强度的概念,并给出了几种典型的决策规则.最后结合一个软启动产品设计方案优选案例对本文研究进行了验证,结果表明.采用基于辩论的群体研讨和决策方法有助于从认知角度来分析决策者的行为动机,可用于解释决策者偏好形成或直接用于决策,从而提高决策的科学性与有效性. The discussion is an effective tool to support groups to jointly solve complex decision-making problems, which is essentially a process of logical speculation and inference among many people.This article draws on the debate theory in the field of artificial intelligence and proposes a group discussion model based on debate Decision-making method.Firstly, the general discussion process and debate process are contrasted and analyzed, and the similarities in the mechanism and purpose of group discussion decision-making and debating process are revealed. Then, the abstract debates framework of Dung is introduced to establish the debating group discussion system framework. This paper discusses the reasoning mechanism and argument strength of argument states and gives some typical decision rules.Finally, a case study of a soft-start product design scheme is carried out to verify the research in this paper.The results show that the discussion based on debates And decision-making method help to analyze the decision-maker’s behavioral motivation from the cognitive perspective, which can be used to explain the decision-maker’s preference formation or directly used in decision-making, so as to improve the scientific and effective decision-making.
