The concept of resilience has gained increasing attention in recent years for its importance and practical implications for a wide range of professionals across different disciplines. To date, much attention has been paid to defining resilience, the possibilities of its measurement, the methodological frameworks for its construction, and simulation models. So far, however, analytical models have not been introduced to assess the resilience according to individual scenarios of its increasing in particular supply chains with regard to costs incurred. The aim of the article is to introduce, analyse and evaluate the possibilities of using modified analytical production line models to optimize investments directed to individual supply chain links to increase its overall resilience. For the purposes of the article, a model example of the structure of the real metallurgical supply chain is used. The possibilities and limitations of individual models and possibilities of their practical implementation in the management of metallurgical supply chains are discussed.Keywords: resilience, supply chain, metallurgy, manufacturing line models, modelling
