Abstract: In this paper, a fuzzy mathematical programming model based on the nested model is proposed to design a sustainable multi-product, multi-period supply chain network (including three parts of the procurement, production and distribution) under the competition and uncertainty conditions. Sustainability measures are carried out using previous studies and the supply chain operations reference (SCOR) model is extracted in each of the sustainability dimensions and then localised using the fuzzy Delphi method. In order to determine the relationship between indicators and the importance of each index, DEMATEL method is used and then the obtained fuzzy model is converted into a crisp one. To demonstrate the efficiency of the model, a real example is presented in the refractory industry. Finally, the results are analysed and suggestions are presented.
