摘　　要：提出一种基于灰色系统理论改进传统理想点法的供应商评价方法,即运用层次分析法(AHP)和熵权法对各项评价指标进行主客组合赋权,同时利用灰色关联分析法对传统逼近理想法进行改进,从而构建出一套新的相对贴近度。依据相对贴近度的大小,对各备选供应商的综合评价值进行排序和择优。结果表明:该方法克服了传统单一赋权方法的缺陷,保证了指标权重的客观性,能准确、有效地避免因排序问题带来的评价误差,使其评价结果更为合理。实例分析表明,验证了灰色关联分析法改进TOPSIS法的有效性和实用性,并为以后的供应商评价提供了一种新的选择方法。On the basis of the existing research and evaluation methods,a supplier evaluation method based on gray system theory to improve the traditional ideal point method was proposed.A reasonable supplier evaluation index system was established by the hierarchical analysis method(AHP)and entropy right method to empower the evaluation indicators.The traditional approaching ideal method was improved by gray correlation.A new relative proximity was build according to the size of relative proximity to sort and select the comprehensive evaluation values of the alternative suppliers.The results showed that the method can accurately and effectively avoid the evaluation error caused by the sorting problem to make the evaluation results more reasonable by overcoming the defects of the traditional single empowerment method and ensuring the objectivity of the index weight.Finally,a new selection method for future supplier evaluation was provided through the example analysis.The effectiveness and practicality of the gray correlation method to improve the TOPSIS method was verified.
