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。
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.
