一种基于不确定信息的决策方法

A Decision Making Method Based on Uncertain Information

提出了一种基于不确定信息的决策方法 ,该方法从统一决策模型的角度给出了候选决策集的构造方法、候选决策从证据焦元获得的属性级支持度的计算方法、决策矩阵的构造方法、候选决策获得的证据级支持度的计算方法等 .该方法的特点在于将基元和非基元决策的选择问题统一起来加以考虑 ,另外 ,决策者可以通过设定模型中的函数形式 。

In this paper, a decision making method based on uncertain information is presented. Under unified model, selection of candidate decisions, calculating method of support degree from property angle that candidate decision obtain from focal elements, construction method of decision matrix, and calculating method of support degree that candidate decision obtain from the DS evidence are discussed. According to our decision making method, basic element decision and non basic element decision are considered under a unified structure. Besides, decision maker can select some certain compromise strategy between decision card and decision risk.
