An important factor of survival in today’s competitive environment is to reduce production costs of products. Choosing the right suppliers can significantly reduce procurement costs and increase the competitiveness of the organization. Increasing concerns about environmental warnings have attracted the attention of customers, governments, and organizations and resulted to take care about environmental requirements for products production. As the majority of products components and its material supply from external suppliers, consideration of supply process indicators is important. Greening supply chain process is an opportunity for those people are taking care of sustainable demand and environmental business performances. We employed TOPSIS to weight and rank and DEMATEL to evaluate relationships of indicators. After computing the weight of indicators, quality received the highest score, as well as environmental performance, achieved the lowest score in our evaluation. After ranking indicators, it has resulted that environmental management and reverse logistic received the highest and lowest in our assessment. The cause and effect relationship of supplier selection indicators in Fulad Gilan Company shows that the reverse logistic, environmental performance as well as cost are the most unaffected rather than other indicators and also the impact of environmental performance, cost and supplier collaboration are higher than other indicators.
