摘　　要：针对二重模糊积分工程实用化,建立了备域上二重可测函数、单调类上二重可测函数的概念。由此出发,从积分函数选择、积分运算方式等方面修正了现有二重模糊积分理论,并给出基于二重模糊积分的综合评判模型。随后,将该理论用于解决一个较为复杂的评估问题——目标识别效果评估,确定了评估指标、评估因素集、因素集元素的权重选取方式、单个评价向量组的生成方法,构筑了评估模型,进行了仿真实验验证。综合评判过程及结果表明了修正后二重模糊积分的科学性、易用性。Aiming at the engineering application of the two-layer fuzzy integration, we established the concepts of ＂two-layer measurable function on domain＂ and＂ two-layer measurable function for the monotone class＂. Based on which, the theory of modified two-layer fuzzy integration was set up, where the integral function and the operation way were revised. The evaluation model based on two-layer fuzzy integration was given. Then, the theory Was used to solve a comprehensive evaluation problem, i. e. , the performance evaluation of Automatic Target Recognition （ATR）. The evaluation indexes and factors, the weight select mode for factors and the generation method of single judgment vector group were determined. A performance evaluation model was constructed and simulation was carried out. The result showed the feasibility and the scientificity of our theory.
