Journal Article 2019 05 14 <strong>Objective:</strong> Improving sustainability in supply chains is one of the strategic objectives in the current business. Hence, firms have adopted new management strategies to achieve sustainability in their supply chain. Therefore, it is essential to assess the sustainability performance of the newly implemented management strategies. The purpose of this paper is to provide a model for assessing the sustainability performance of LARG supply chain management practices in the automotive supply chain using the dynamics system. <strong>Methods:</strong> LARG supply chain management practices were identified, by reviewing the literature and interviewing industry experts, prioritized using fuzzy analysis network process, and were eventually presented as an integrated approach to LARG supply chain management practices. Finally, the dynamic system has been used to assess the dynamics of LARG supply chain management practices and their impact on sustainable performance in the supply chain. <strong>Results:</strong> The research findings show that improved measures in the implementation of total quality management, just in time, flexible transportation lead to a more sustainable supply chain. The results of these measures show sustainability improvement in the supply chain. <strong>Conclusion:</strong> The results show that a lean strategy is very important for achieving sustainability in the supply chain. The proposed model helps industry managers and decision makers identify the results achieved from implementing LARG supply chain management practices and improving effective practices on sustainability in the supply chain by adopting policies. https://imj.ut.ac.ir/article_78099_4402ce02abe6ba131c3836933343c458.pdf
