Application of gray DEMATEL-ANP in green-strategic sourcing

The study aims to identify and prioritize the criteria and sub-criteria dimensions essentials for green strategic sourcing. Data were taken from the experts working in the automobile industry. By applying the novel Grey-DEMATEL-ANP (GDANP) approach, we identified the technology and environmental management system as the key sub-criteria dimensions to be considered while selecting the supplier. Besides, we also found quality and delivery time as the important factors to be considered while selecting a supplier for green supply chain management (GSCM). To present the useful application of our findings, we conducted an empirical study by taking the automobile industry of an emerging market as the case. The major contribution of the study is the application of variant D-ANP in identifying the important dimensions of supplier selection.
