Fuzzy Evaluation of Railway Environmental Noise Based on MATLAB
摘要
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 were got from the level eigenvalues which were picked up by the optimal relative membership degree matrix. According to fuzzy comprehensive evaluation procedure of railway environmental noise, railway environmental noise fuzzy evaluation software was developed based on Matlab. After using the software to evaluate three housing estates, the results show that the first and the third housing estates are lightly polluted while the second one is moderately polluted by railway noise.关键词
