Abstract
Abstract In order to assess index weighted value scientifically, the fuzzy mathematic and the matter element were introduced into the fuzzy weighted values to set up matter element model based on fuzzy weight. In this way, the model not only holds the merit of classical matter element, but also overcomes its limitations in practice. The model was applied to evaluate the development of circular economy in Beijing, Anhui, Sichuan. It is shown that the quality grade of Beijing is good circle (I), Anhui is middle circle (II) and Sichuan is basic circle (III). The proposed method is proved to be reasonable and reliable, and can be widely used in all kinds of comprehensive evaluation problems.
