The pandemic caused by the COVID-19 virus has had negative effects on different industrial sectors, the world economy and especially on Supply Chains. The pandemic revealed the vulnerability of key logistics processes of companies and their Supply Chains as operational risks increased, causing breaks in inventories, production lines and the distribution process caused by increased customer demand. However, this pandemic makes it necessary to reevaluate the models and strategies that companies had established as the standard, and more was needed to face the shortage of components, raw materials and inputs needed to keep the production processes active. Therefore, this article proposes developing a conceptual model under the System Dynamics methodology, which allows identifying the main impacts that the COVID-19 pandemic had on the performance of the Supply Chain through the design of Causal Loop Diagrams.

Supply chain simulation has been used to analyze possible scenarios, and one of the most used techniques is system dynamics, and although there are some literature reviews on this topic, the number of papers has increased in recent years, so it is necessary to analyze trends, locate the most relevant research groups, authors, and papers. This article reports a bibliometric review on the dynamic system applied to the supply chain on engineering and analyzes 519 documents found in the Scopus and Web of Science databases using PRISMA methodology and VosViewer software. Findings indicate that China, the United States of America and the United Kingdom are the countries that produce the most papers, although Cardiff University is the institution with the most consolidated research groups. The most productive authors are Towill, D.R., Naim, M.M. and Rabelo, L., although the most cited are Towill, D.R., Naim, M.M. and Wikner, J., while the Journals that most publish this topic are the International Journal Of Production Research, International Journal Of Production Economics and the Journal of Cleaner Production.
