在过去的几十年里，绿色供应链管理的概念应运而生，因为公众的环境保护意识日益增强。由于企业倾向于将各种活动外包出去，绿色供应商选择作为绿色供应链管理的一个必不可少的功能，在帮助企业保持战略竞争力方面具有至关重要的作用。尽管有太多的研究介绍了基于经济标准的供应商选择模型，但考虑到环境问题的研究相当有限。在这项研究中，提出了一个综合考虑经济指标和环境指标的灰色供应商选择模型。将最优-最差方法和模糊灰色认知图相结合，提出了一种新的权重分配模型，以捕捉准则之间的相互依赖关系。提出了改进的灰色关联分析方法，能够使用标准的灰色权重来评价绿色供应商，然后使用区间分析方法对其进行排序。本研究通过解决现有绿色供应商选择模型的不足，为决策理论的研究做出了贡献。文中还给出了一个实际案例研究，验证了该模型的适用性和有效性。这项研究的结果证明，所提出的综合模型能够很好地解决绿色供应商选择问题，因为它考虑了标准之间的相互依赖关系以及与专家判断相关的不确定性。(C)2019爱思唯尔有限公司。保留所有权利。
The concept of green supply chain management emerged as a response to increasing public awareness of environmental protection in the past few decades. As companies tend to outsource a variety of their activities, green supplier selection as an imperative function of green supply chain management, has a crucial role in helping companies to maintain their strategic competitiveness. Despite the plethora of studies introducing supplier selection models based on economic criteria, studies that take into account the environmental issues are rather limited. In this study, a comprehensive grey-based green supplier selection model is proposed that incorporates both economic and environmental criteria. A novel weight assignment model is proposed by combining best-worst method and fuzzy grey cognitive maps to capture the interdependencies among the criteria. Improved grey relational analysis is advanced to be able to use grey weights of criteria to evaluate green suppliers which are subsequently ranked using an interval analysis approach. This study contributes to the decision-making theory by addressing the shortcomings of the available green supplier selection models. A real-world case study is also presented to show the applicability and effectiveness of the proposed model. The results of this study proved the proposed comprehensive model to be well capable of addressing the green supplier selection problem by taking in to account the interdependencies between criteria as well as the uncertainties associated with experts' judgments.
