Key words: In order to solve the problem that the direct interval extension of TOPSIS method with the same center number can't be compared, the interval extensions of TOPSIS method in this article is improved. At the same time, the existing TOPSIS method on interval numbers mainly focuses on static evaluation, combined with improved interval extensions , of TOPSIS method, improved dynamic TOPSIS evaluation method of interval , numbers is proposed in this paper. First, the problem of applying , uncertain interval numbers to TOPSIS is discussed. The research of TOPSIS , method is extended to fuzzy multi-attribute decision-making whose attribute , value is interval number. Then the shortcomings of a direct interval extension , of TOPSIS method are analyzed, and the effectiveness of the method is verified , by several simple examples. Additionally, the evaluation value of each time , period is aggregated by the time weights, and the comprehensive evaluation , results of each scheme are obtained. Finally, an example is applied to , verify the rationality of the proposed method.
