 Abstract:The purpose of this paper is to present a new model of non-radial data envelopment analysis that is able to evaluate the systems one of these complete networks is supply chain of cement industry. 
In this paper, using a non-radial model in data envelopment analysis, a model with a network structure that can assess the sustainable supply chain of strategic industries is evaluated. In addition to commonly used financial and technical indicators, undesirable outcomes and sustainability criteria should be considered in the supply network.
The new model was tested on the basis of actual data from 42 existing cement companies in the stock market. The results showed that this model could well evaluate performance in a networked structure. Based on the implementation of this model, 7 supply chains have been able to achieve efficiency.
