Using fuzzy DEMATEL to evaluate the green supply chain management practices

Green supply chain management (GSCM) has become a proactive approach to enhance environmental performance. Under stakeholder pressures and regulations, firms need to enhance GSCM practice, which are influenced by practices such as green purchasing, green design, product recovery, and collaboration with customers and suppliers. As proactive firms adopt GSCM, their economic performance and environmental performance will be improved. Hence, this study aims to examine the influential factors among eight criteria of three main GSCM practices, namely practices, performances, and external pressures. To deal with the vagueness of human being's perceptions, this study utilizes the fuzzy set theory and decision making trial and evaluation laboratory method to form a structural model to find out the cause and effect relationships among criteria. The results and managerial implications are discussed. (C) 2011 Elsevier Ltd. All rights reserved.
