Using DEMATEL to develop a carbon management model of supplier selection in green supply chain management

This study aims to utilize the Decision-making Trial and Evaluation Laboratory (DEMATEL) approach to recognize the influential criteria of carbon management in green supply chain for improving the overall performance of suppliers in terms of carbon management. Thirteen criteria of carbon management with three dimensions were identified from literature review and interview with three experts at an electronics manufacturer. By considering the interrelationships among the criteria, DEMATEL was applied to deal with the importance and causal relationships among the evaluation criteria of supplier selection. Obtained results show that the criteria of management systems of carbon information and training related to carbon management are revealed to be the top two significant influences in selecting suppliers with carbon management competencies. By identifying the structures and interrelationships, it can offer an insight for managers to understand cause-effort relationships and allow to select suppliers who are capable of having competence in carbon management and to improve suppliers’ performance.
