Journal Article 2017 08 21 Green supply chain management is a crucial challenge for the sustainable development of the enterprises. In this paper, we study the problem of supplier selection for the multi-attribute and multi-source green procurement of electric coal under fuzzy information environment. Concretely, we establish a new index system of supplier selection by considering both the economic factors and environmental factors, and then present a multi-attribute decision making method based on 2-tuple deviation degree to rank all alternative suppliers in the green procurement of electric coal. We also highlight the implementation, availability, and feasibility of the green procurement decision method of electric coal by using an example of the multi-source procurement of electricity coal. We try to provide theoretical basis and decision-making reference for the thermal power enterprise to implement scientific green procurement management of electric coal. https://scientiairanica.sharif.edu/article_20194_eac30075f2caac8309fb498fc160efef.pdf
