Abstract

Water quality evaluation is a key step in water resource management. The water quality evaluation problem is a multi-attribute decision making problem because there are many indicators considered in the evaluation process. The aim of this study is to put forward a new water quality evaluation method based on variable weight method. The new evaluation method takes both the relative importance of factors and the horizontal configuration of the value of each indicator into consideration. Finally, a practical example demonstrates that the proposed method is effective and feasible.

Keywords:
