Green supplier selection using topsis method: A case study from the automotive supply industry
Abstract
Climate change and increasing global warming have raised increasing environmental concerns around the world. Firms seeking to gain and maintain competitive advantages in the global market began to focus on the development of green products to meet customers' environmental requirements. As a result, green supply chain management (GSCM) through environmental procurement has become an important task for companies. Accordingly, green supplier selection has gained importance with the addition of environmental criteria to traditional supplier selection processes. In this study, it is aimed to select the best green supplier for a large scale company operating in the automotive supply industry and exporting the majority of its products. Environmental management system, reverse logistics applications, environment-friendly material use, waste management, pollution, and pollution level are selected as green supplier selection criteria. Five alternative green suppliers identified by the firm are evaluated using the TOPSIS (Technique for Order Preference by Similarity to Ideal Solutions) method according to these criteria. At the end of the study, the best green supplier selection is made considering the sensitivity analysis results.
