Water Enviroment Fuzzy Comprehensive Evaluation Model Based on Information Entropy
The fuzzy mathematics method is combined to establish an improved fuzzy comprehensive assessment method which is based on information entropy. On the base of fuzzy comprehensive evalation model,the introduction of the information entropy has revised the weight coefficient with the overstandard ratio. Meanwhile the validity of results are judged by the validate index,the selection nearness principle which based on closeness degree is given to get the new assessments of ineffective results. According to the water environment assessment characteristics,then the model is deployed in water quality evaluation. A case study is given by using this model and the result compared with the other methods shows that the model established in this paper is strict and reliable,and it is worthily extending.
