摘要
针对不确定条件下的群体研讨决策问题,提出了一种基于证据理论的辩论模型。首先构建了辩论系统的框架,论据的内部结构由前提和结论组成,论据之间不仅存在攻击和支援关系,还允许对这种攻击和支援关系进行支持或反对。然后引入证据理论描述论据的不确定性,应用证据映射方法对辩论过程进行不确定性推理,实现对论据信度的数值计算。最后,通过仿真实例验证了模型的有效性。
For the problem of group decision under uncertain conditions,an argumentation model based on evidence theory is proposed.To realize the model,the argumentation framework is firstly built,where the arguments are consisted of premise and conclusion.In this argumentation framework,not only the relationship of attack and support is existed between the arguments,but also support or opposition for the relationship of attack and support between the arguments is permitted.Then,through introducing the evidence theory to describe the uncertainty of the arguments and the uncertain reasoning for the argumentation process based on evidence mapping,the credibility of the arguments can be computed.Finally,an example is provided to demonstrate the validity of the proposed model.
