Research and Application of Fuzzy Multi Attribute Decision Making Based on Information Entropy and Grey Relevance Degree

摘要

With the development of uncertain theory,fuzzy multi attribute decision making has been applicated in more and more areas.Considering of previous fuzzy multi attribute decision methods,some were based on information entropy,some were based on grey relevance degree,etc.Information entropy is a kind of quantity of the system uncertainty and grey relevance degree can indicate the correlation strength between different things.In this paper,a new fuzzy multi attribute decision method is presented which combines information entropy with grey relevance degree,this method well overcomes the incompleteness and indeterminacy of the information,and provides a feasible way for fuzzy multi attribute decision making.Finally,the validity of this method is verified by an example.
