基于最优组合赋权的可变模糊模型在水质评价中的应用
Application of variable fuzzy model based on algorithm of optimal combination determining weights to evaluation of water quality
摘要
Abstract
Current methods for the evaluation of surface water quality have problems of fuzziness , uncertainty , and questionable approaches to determining weights .To solve these problems , an algorithm of an optimal combination determining weights model was used to optimize the combination of the subjective and objective weights on the basis of variable fuzzy set theory .A case study was conducted in Anshan City .With the software Matlab , the subjective and objective linear coefficients of the optimal combination determining weights mathematical model were determined to be 0.6 and 0.4 , respectively .Based on the variable fuzzy model , the surface water quality of Anshan City was evaluated , and the results were compared with those of the fuzzy comprehensive evaluation method and the gray correlation analysis method , and with observed results .This study shows that the results obtained by the proposed model are applicable to the actual conditions of the study area , and the model is scientific , reasonable, reliable, and easy to operate.关键词
