In this paper, a fuzzy mathematical programming model is proposed for designing a sustainable multi-product, multi-stage supply chain (including, purchase, production and distribution) under the competition and uncertainty conditions.  The sustainability measures in each of the sustainability dimensions were extracted using earlier conducted research as well as the SCOR model and then were localized using the Delphi method. The obtained fuzzy model is converted to a crisp one by using Jimenez model. The solving approach is based on the Triple Bottom line model and the Nested model. As each model has its own characteristics, in order to determine the relations between the indices and the importance of each indicator and its application, the DANP and DEMATEL methods were used respectively.  In order to indicate the efficiency of the model and the solution approach, a real example is presented in refractory products industry, and finally the obtained results are analyzed and compared based on the two models and suggestions are presented.

Keywords: TBL Model, Nested Model, Competition, Uncertainty, SCOR Model, DANP Method, DEMATEL Method
