Developing a Model for Green Supplier Selection Based on Environmental Performance Approach Using MCDM (Application to Selected Tile Companies of Yazd Province)

Nowadays, environmental management focusing on environmental protection has become a challenging issue to business organizations as a result of global and local environmental problems. There has been increasing interest towards firm’s environmental sustainability activities to improve practices in their supply chain. This challenge has led to a new concept called green supply chain management (GSCM) in business field that is the combinations of environmental thinking and supply chain. Since Yazd province is industrial pole of tile and ceramic in Iran, and because of high pollution in this industry, authorities are forced to follow environmental laws and produce environment- friendly products. For doing so, they choose factories that protect the environment in the supply chain which can be considered as a competitive advantage for them. In this regard, this study ranks the selected tile companies in Yazd province based on green supply chain. For this purpose, a questionnaire has been used that assess the green supply chain using six criteria including green supplier and purchasing, green design, green manufacturing, green distribution, green packaging and green production costs. Finally, to rank the companies two multi-criteria decisions making techniques, PROMETHEE and OWA, have been used. Ranking the selected tile companies of Yazd based on MCDM methods showed that respective companies B and C have better and worse condition in producing environmentally friendly products. The results showed that there is little difference between these two MCDM methods (OWA and PROMETHEE).
