Increasing customer satisfaction by producing quality products at a low cost is an important issue for businesses. For this reason, companies have to choose suppliers that will best meet their and their customers’ requests. Besides, many factors such as increasing the importance given to the environment, increasing the recycling rate of the products and ensuring sustainability are in an important position in the selection of suppliers. This has created the concept of green supplier selection. Businesses now prefer suppliers that carry out production considering green factors. In this study, green supplier selection was performed for a company producing steel doors. Alternative suppliers of the steel sheet raw material used in the company and the green criteria taken into account when choosing these suppliers were determined. Afterward, the company’s managers were interviewed and an evaluation and comparison of criteria and suppliers were carried out. The fuzzy analytic hierarchy process method was used to determine the weights of the determined criteria. The fuzzy multi-objective optimization by ratio analysis method was used in the evaluation and selection of suppliers. As a result of the study, the suppliers were listed as T1 > T2 > T4 > T5 > T6 > T3. It was decided that the best supplier for the company is the T1 supplier.

基于模糊层次分析法和模糊Moora方法的钢门行业绿色供应商选择

通过以低成本生产优质产品来提高客户满意度对企业来说是一个重要问题。因此，公司必须选择最能满足其及其客户要求的供应商。此外，提高对环境的重视程度、提高产品的回收率、确保可持续性等诸多因素在供应商的选择中都处于重要地位。这创造了绿色供应商选择的概念。企业现在更喜欢考虑绿色因素进行生产的供应商。在这项研究中，对一家生产钢门的公司进行了绿色供应商选择。确定了公司所用钢板原材料的替代供应商，以及在选择这些供应商时考虑的绿色标准。之后，公司的管理人员接受了采访，并对标准和供应商进行了评估和比较。模糊层次分析法用于确定确定标准的权重。在供应商的评价和选择中采用了基于比率分析法的模糊多目标优化方法。作为研究的结果，供应商被列为 T1 > T2 > T4 > T5 > T6 > T3。决定公司的最佳供应商是 T1 供应商。作为研究的结果，供应商被列为 T1 > T2 > T4 > T5 > T6 > T3。决定公司的最佳供应商是 T1 供应商。作为研究的结果，供应商被列为 T1 > T2 > T4 > T5 > T6 > T3。决定公司的最佳供应商是 T1 供应商。
