摘　　要：为解决评价过程中分类等级的边界不确定性问题,将二型模糊集引入到模糊综合评价模型中.利用分类等级的边界限值,分别构造三角形二型区间模糊数的上、下隶属函数,在此基础上由观测数据构建相应的区间值模糊评价矩阵,结合指标权重合成得到区间值综合评价向量,最后利用区间数排序的可能度方法得到评价对象的等级隶属向量并给出评价结果.实例分析表明了该模型的有效性。In order to solve the boundary uncertainty on classification grade problem in the evaluation process,the type-2 fuzzy set is introduced into the fuzzy comprehensive evaluation model.By the boundary value of classification grade,the upper and lower membership function of triangle interval type-2 fuzzy number is constructed.Furthermore,the interval fuzzy evaluation matrix is built on an amount of observation data,and then the interval comprehensive evaluation vector is obtained by integrating the weight of indicator.Finally,with using the rank method of interval number based possibility degree on the obtained interval evaluation vector,the membership vector of evaluation objects is obtained,and the final results are reported.An illustrative example indicates the validity of this model.
