According to independence and non-compatibility of indexes in the evaluating of water quality, this research builds up a new model based on coefficient of entropy to evaluate water quality, which combines entropy value theory and grey relating degree together. Entropy value method is adopted to calculate coefficient of weight and this avoid problems of distribution difficulty through using experts'...
In view of the deficiency of classic method evaluating water quality. A grey relational analysis model is proposed to evaluate water quality in river. The principle of grey relational analysis and its process are introduced. Suzhou river was selected and assessed by using this method. And it was found that, compared with the fuzzy complex judgment method, the result was remarkably different. The possible...
Evaluation of water environment quality plays an important role in environment science. Because of many factors affecting environment quality, it is a basic task to select rational pattern and make full use of limited information from monitors so as to describe environment quality objectively. In view of the deficiency of the traditional methods, based on the grey theory, a grey clustering model is...
In order to overcome the weakness of subjectivity in determining weight coefficient of fuzzy comprehensive evaluation method, an attributes recognition method based on coefficient of data-driven is built up, and the weight is determined by the data-mining thinking through comprehensive utilization of classification criteria information and sample information. Utilization of this model to evaluate...
