It is of special importance to procure medicines as strategic commodities. The purpose of this study is to manage a drug supply network using a non-radial data envelopment analysis (DEA) model. This study is conducted in private hospitals in Tehran. In this regard, a drug supply chain at three levels of suppliers, distributors, and consumers (pharmacies and hospitals) is examined. Indicators and limitations of the network are identified and then the appropriate model is formulated using mathematical equations on the basis of a non-radial DEA model. In order to validate the proposed model, data related to 30 hospitals during 2019 and 2020 is evaluated. According to this model, 5 hospitals had efficient supply networks and 25 hospitals had deficient supply networks. The proposed new model is able to evaluate the multilevel supply network and intermediate components in hospitals. The problems of the drug supply network are due to the increase in demands for the time period under consideration and the existence of inconsistencies in the drug supply chain in hospitals, which has led to an increase in inefficient hospitals.

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.
