Several methods have been introduced for supply chain management, the most prominent of which is large-scale supply chain management. Given the importance of the subject, this study attempts to evaluate and analyze in a single set, by carefully examining the literature presented, the most important requirements of the large-scale supply chain management strategy in the oil industry, which is one of the industries that affects the economy. These issues in the supply chain, which can reduce the productivity and competitiveness of the company in the oil industry, are factors that prompted the researcher to study the pathology of the supply chain in the oil industry and the Abadan Oil Refinery. In this regard, multi-criteria decision-making techniques will be used to diagnose and rank important indicators of the supply chain, including the supply of raw materials, systems, and human resources, so that if the rank of each damage in the supply chain is determined, appropriate suggestions and solutions will be provided for it, and those that are more damaged will be taken into account in a broader perspective. New strategies will also be used in this study. Lean, agile, resilient, and green are paradigms that have been proposed so far with the aim of examining and improving supply chain performance. Each of these four paradigms has different goals and is essential for creating an efficient and effective supply chain in responding to different customer needs. In the research conducted, one or a combination of several paradigms has been used, and in the present study, due to its importance, comprehensiveness, and the possibility of comprehensive and maximum examination of the oil industry supply chain, all four paradigms have been used in order to understand the interaction between these paradigms in this chain, and to present a suitable model for diagnosing and improving the oil industry supply chain using the results of the studies conducted at the Abadan Oil Refinery as the study unit.
