摘　　要：中介逻辑是一种以清晰的和模糊的事物为研究对象的非经典逻辑系统。基于中介逻辑与距离测度,以中介真值程度函数为工具,建立了模糊评判矩阵,并综合评判因素中肯定信息与否定信息的真值程度确立评判指数,进而以评判指数作为总体评判的数量依据,对评判对象进行比较,从而建立了一种新的模糊评判模型;并讨论了它在一个具体的模糊评判实例中的应用。Medium logic is an non-classical logic system about researching distinct objects and fuzzy objects. Based on medium logic and distance measure, fuzzy evalution matrix is established with medium truth fade function, and the index of fuzzy evalution is educed by considering positive information and negative information of fuzzy evalution factors. Then the evaluation objects are compared by the evaluation index which is regarded as the basis of comprehensive evaluation. Therefore a new kind of fuzzy comprehensive evaluation model is constructed, the application of which is discussed by an example in the end of the paper.
