An effort that can be made to increase productivity is the performance of supply chain management. Sustainability in the supply chain, which takes into account the serious environmental challenges, prevents the production of any kind of pollution from human life by producing green products. The main purpose of this paper is to provide a Multi-Stage Data Envelopment Model to Assess the Sustainable Supply Chain Network of Rubber Producing Companies. The methodology of this research is analytical-descriptive and in terms of purpose is applied. One of the techniques that can be used to evaluate the performance of a stable supplier is data envelopment analysis. The research community in this study is 10 rubber companies whose performance has been evaluated over the past three years in 2013, 2014 and 2015. Based on the results, in 2013, Simorgh and Pars tires were ranked one, in 2014, Barez Tire and Pars Rubber ranked one, and in 2015, Barez Tire, Kavir Tire, Pars Tire and Iran Tire ranked one.
