Abstract:

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.
