A case study of using DEMATEL method to identify critical factors in green supply chain management

This case study uses four dimensions and twenty factors developed by Hsu and Hu [5] suitable for electrical and electronic industries in Taiwan to identify the critical dimensions and factors and then construct the digraphs to show causal relationships among dimensions and factors within each dimension in green supply chain management (GSCM). Ten major customers of this case group were invited from international semiconductor packaging plants to evaluate dimensions and factors by decision making trial and evaluation laboratory. The results show that both organization involvement and supplier management are causes, and organization involvement is the most critical dimension in GSCM. Moreover, top management support and environmental policy for GSCM are the two critical factors in organization involvement that should be placed in highest priority when GSCM is to be implemented. In addition, establish environmental requirements for purchasing items and implementing green purchasing are the two important factors in supplier management. The decision maker can take actions on causal dimensions/factors in high priority in GSCM since the implementation on these causal dimensions/factors will have impacts on receiving dimensions/factors in GSCM implementation.
