证据的层次推理技术及其应用

The hierarchical reasoning technique of evidence theory and its application in synthesis evaluation

应用证据理论实现对评价结果的不确定推理,提出证据的层次推理模型,明确证据对结论的支持关系,当证据发生变化时,只需调整相关层次上的综合参数,使得模型更加实用,通过算例,对该模型在综合评价中的应用进行了讨论并证明其合理有效。

To deal with the uncertainties in synthesis evaluation, the paper uses evidence theory to achieve the reasonable results. Bring forward the hierarchical structure model in evidence reasoning. If the evidence varies, the synthesis references need to be justified on the correlation layer. The hierarchical structure model in evidence reasoning is discussed.The application of the model shows that it is efficient and valid in uncertainty reasoning.
