| 摘 要： | 由于某种铁路环境噪声模糊评价方法存在应用的局限性,采用改进的相对隶属度建立指标隶属度模糊矩阵对原方法进行改进.依据模糊数学原理,由改进的实测值隶属度模糊矩阵、改进的指标标准值模糊矩阵和指标权重向量计算得到最优相对隶属度矩阵.由最优相对隶属度矩阵提取级别特征值,得到评价结果.根据铁路环境噪声模糊综合评价步骤,基于Matl...

| Abstract: | Since there were application limitations in certain fuzzy evaluation model for railway environmental noise,the fuzzy matrix of index membership degree was constructed by adopting the improved relative membership degree to improve the original method.Based on the fuzzy mathematical theory,the optimal matrix of relative membership degree was obtained by the improved fuzzy matrix of the measured membership degree,the improved fuzzy matrix of index criteria values and index weight vector.The evaluation results ... |
