利用证据理论中的基本概率分配函数、信任函数和似然函数来描述和处理知识的不确定性。提出一个特殊的概率分配函数和新的组合规则,并以其为基础建立一个不确定性推理模型。实例证明该模型能有效地度量最终结论的不确定性。
Use of the basic probability assignment function,the belief function and the plausibility function in evidence theory to describe and deal with the uncertainty of knowledge. This paper advised a specific probability assignment function and a new combination rule,and established a model of uncertain reasoning based on it. The example shows that the model can effectively measure the uncertainty of the final conclusions.
