It is investigated that the thoughts of sustainability gained the momentum among researchers in the present era. The industrial empirical research survey proved that green operations, waste minimization strategies, and zero defect planning are three potential pillars in mapping the sustainability of supplier/vendor units. The authors built and proposed a grey knowledge-based green-waste minimizing and zero defect (GWmZd) sustainability appraisement hierarchical structural evaluation model/framework to production companies for assessing the sustainability ratio of their candidate suppliers/partners. Due to the uncertainty associated with the measures and metrics of the proposed model, the incomplete information is procured from a cluster of professionals’ vs GWmZd measures and metrics in the terms of the grey (except fuzzy) set. It is sensed by the prior literature survey that a few grey knowledge-based sustainability model are framed, but they were constrained to the individual first level layer without weight evaluation cum noncomparative analysis-based modern technique, and it is respected as a major research gap and challenge. To compensate the major research gap, the authors elected AHP and enabled AHP (analytic hierarchy process) to materialize and aggregate the assigned rating of each expert for evaluating weights of 2^nd level metrics (overcoming the drawback of combined/group ratings). Later, the authors structured and proposed a new mathematical equation, assisted authors to evaluate the global weight of the first layer-three pillars-measures of the proposed model. Eventually, the authors constructed and fruitfully implemented a grey-holistic technique (merger of grey-MOORA-FMF fused with the dominance theory) on the model to compute sustainability index and score of suppliers. A production company is investigated to exhibit the application of the research work practically. The sustainability of supplier A₁ is found the best than the residue of suppliers. The research forum can be explored by production companies to opt the feasible supplier under the proposed model. The conducted research has a value across the global production companies. The research forum can be explored by managers of production companies for benchmarking the performance of global suppliers under GWmZd and future advancing models along with grey-holistic technique fused with the dominance theory.

通过探索基于知识的灰色整体技术开发GWmZd模型以进行可持续供应商评估

据调查，可持续发展的思想在当今的研究者中得到了发展。工业经验研究调查证明，绿色运营，废物最小化策略和零缺陷计划是绘制供应商/供应商单位可持续性的三个潜在支柱。作者为生产公司建立并提出了一种基于灰色知识的绿色废物最小化和零缺陷（GWmZd）可持续性评估层次结构评估模型/框架，以评估其候选供应商/合作伙伴的可持续性比率。由于与所提出模型的度量和指标相关的不确定性，不完整的信息是从一组专家对GWmZd度量和指标中以灰色（模糊除外）集的形式获取的。先前的文献调查表明，已经构架了一些基于灰色知识的可持续性模型，但是它们被限制在单独的第一层，而没有权重评估和基于非比较分析的现代技术，因此被认为是主要的研究空白和挑战。为了弥补主要的研究差距，作者选择了AHP，并使AHP（层次分析法）能够具体化和汇总每位专家的指定评分，以评估2的权重^第二级度量（克服组合/组的评分的缺点）。后来，作者构造并提出了一个新的数学方程式，以帮助作者评估所提议模型的第一层-三支柱-度量的全局权重。最终，作者在模型上构建并有效地实施了灰色整体技术（灰色-MOORA-FMF与优势理论的合并），以计算可持续性指数和供应商得分。对一家生产公司进行调查，以实际展示研究工作的应用。供应商A ₁的可持续性被发现比供应商的残留物最好。生产公司可以探索该研究论坛，以根据提议的模型选择可行的供应商。进行的研究在全球生产公司中都具有价值。生产公司的管理者可以探索该研究论坛，以在GWmZd和将来的推进模型下，结合灰色整体技术和优势理论，对全球供应商的绩效进行基准测试。
