Integrating environmental performance into the supplier evaluation: A GRA-based method

The Green Supply Chain Management (GSCM) takes environmental considerations into the account in supply chain management. Purchasing decisions have significant impact on the GSCM. However lack of effective and practical tools for supply chain managers to incorporate green into their daily operations hindered the practice of GSCM. The paper establishes an integrated supplier evaluation model considering supplier's environmental performance together with price, production capability, reliability and service. The method of Gray Relation Analysis (GRA) is adopted to compare and rank the potential supplier's performance in these dimensions. A case study is conducted to demonstrate the application of the proposed the method.
