基于混合模糊DANP与改进灰色关联理论的绿色供应商评价研究

摘要

本文通过混合模糊DEMATEL-ANP 方法与灰色关联理论建立了绿色供应商的评价模型,在利用DEMATEL方法确定评价标准的基础上采用ANP 方法确定标准的权重值, 进而通过改进的灰色关联分析方法并以理想值与容忍值替代传统的参考序列所得到的新的评价指数可靠性大大提高, 能够在一定程度上克服目前已有模型的局限, 优化供应商的选择.%This paper proposed a model for evaluating green supplier by combining fuzzy Decision Making Trial And E -valuation Laboratory (DEMATEL) and Analytical Network Process (ANP) methods.Through DEMATEL method, we i-dentified the criteria for evaluating supplier .Based on the analysis result , ANP method was used to determine the differ-ent weight value of the criteria .Furthermore , modified grey relation method is integrated into this model .We replaced the traditional reference sequence with the new evaluating index calculated by the ratio of the ideal value and tolerance value , which improved the reliability of the evaluating result .The model overcame the limitations of the present green supplier e-valuation model and optimized the selection of green supplier .
