%X 摘要： 提出一种基于余弦相似性的改进TOPSIS(technique for order preference by similarity to ideal solution)法并将其应用于解决供应商选择的问题。夹角余弦的距离度量方式隐含了传统TOPSIS法中属性权重,提高了决策的客观性。在供应商选择的实例上证明了所提方法有较强的科学性和合理性。<br>Abstract: An improved TOPSIS(technique for order preference by similarity to ideal solution)based on cosine similarity was proposed and applied to supplier selection. The distance metric based on cosine similarity implicated the weights of attribute in the traditional TOPSIS, and then the proposed method could improve the objectivity of decision. An application on supplier selection was given to show the strong scientificalness and rationality of the proposed method
