Abstract
To assess the shares of each indicator of environmental and economic benefits in iron and steel enterprises, the entropy weight
fuzzy comprehensive evaluation model is built in this paper based on the consideration of entropy theory and fuzzy mathematical
theory. The weights of each indicator are determined by entropy optimal theory, and the correlative indicators are processed by
fuzzy synthesis evaluation, so as to provide some references for environmental and economic benefits evaluation. Lastly, the
feasibility of this evaluation is issued by two typical iron and steel enterprises, and this model is proved to be more objective than
other methods.
