摘要
结合煤业集团的实际,提出了绿色供应商选择的指标体系。利用粗糙集的属性重要性确定指标的客观权系数,并和主观权系数合成为综合权系数,利用综合权系数和灰色关联系数合成为加权灰色关联度。利用熵理论确定出序列的均衡度,将均衡度和加权灰色关联度合成为均衡接近度,并以此作为评价准则,从而可以使灰色综合评价的评价结果更符合客观实际。利用建立的指标体系和改进的供应商选择模型对平顶山煤业集团战略供应商进行了选择应用,得出了其最佳的供应商。
System of indices for green supplier selection was put forward based on Coal Industry Group.Objective weights were ascertained via attribute significance in rough set.Comprehensive weights were derived from objective weights and subjective weights.Weighted grey correlative degree was synthesized by grey correlative coefficient and comprehensive weights.Balanced degree was ascertained by entropy theory.Balanced adjacent degree,which was derived from weighted grey correlative degree and balanced degree,was taken as the evaluation criteria in the improved model.Therefore,grey synthetic evaluation result is more reasonable.The indices system and evaluation model above were applied in the green supplier selection for Ping Dingshan Coal Industry Group.The best supplier was found out.
