Abstract: The vendor evaluation is a problem of multi-attribute group decision making. Due to the vagueness of the evaluation information,a new method based on AHP and two-tuple linguistic is presented,in which AHP is used to determine the weights of the evaluation indexes and the operators of two-tuple linguistic is used to aggregate the information.Moreover,the calculation steps of vendor evaluation and selection is given.Finally,an example is used to illustrate the validity and simplicity of the method.

Key words: vendor evaluation and selection, AHP, two-tuple linguistic, TOWA, group decision making

摘要: 供应商评价是一个多指标群决策问题。针对语言评价信息的模糊性,提出了一种基于层次分析法和二元语义的评价方法。利用层次分析法确定供应商评价指标权重,采用近年来最新发展的二元语义和算子进行信息的集结,给出了供应商评价选择的计算步骤。最后,算例分析证明了该方法的简便性和有效性。
