چکیده:
Nowadays stakeholders and public awareness have increased the pressure on companies for environmental issues. Thus, green supply chain management (GSCM) seems vital for companies' environmental compliance and business growth. Companies continuously seek novel ideas and methods, that can enable them to obtain and/or maintain environmental sustainability. Greening the supply chain is one such innovative idea that rapidly spreads in the industry. The traditional internal measures, such as performing waste-reduction strategies, installing pollution control technologies, substituting hazardous-materials with environmentally friendly ones, are becoming less important as companies strive to find more innovative solutions. Accordingly, the main objective of the present study is to find interrelationship among green supplier criteria. For this to happen, we investigated experts' opinions through nominal group technique (NGT) to find out the interrelationship and causal preferences of the green supplier evaluation aspects using Decision-Making Trial and Evaluation Laboratory (DEMATEL) method. A numerical example demonstrates the application of the proposed model.

The Analytic Network Supplier Evaluation Model for Green Supply Chain, proposed in this study, suggests that the supplier evaluation criteria fall into six dimensions: competitive pricing and cost, reliability, production capability, service, environmental performance and pollution control.
The model is aimed to help companies and supply chain managers to adapt to uncertainties and complexities in the real world, and to find a suitable tool for evaluating and controlling the green suppliers through different approaches.
Our review shows that although some mathematical programming approaches based on multi-criteria decision making methods have been used for the green supplier evaluation in different studies, they have a main weakness which is their inability to include interrelationships within the criteria in the model.
Figure 1: The Analytic Network Supplier Evaluation Model for Green Supply Chain DEMATEL method consists of four steps which are delineated as follows.
Modeling the DEMATEL for determining interrelationship among criteria to evaluate supplier performance Developing a practical model in green supply chain context, which can help organizations and supply chain managers make decisions that are more effective.
