Nowadays, when the variability of markets and the complexity of products are growing rapidly, their life cycles are shortening, and the influence of global supply chains is increasing, companies must reflect on these changes and, therefore, strive to be more flexible, cheaper and faster. Industry 4.0 provides solutions and ways for companies to cope with these challenges. Digital connectivity will improve efficiency and accelerate innovation, introducing new business models that can be implemented much faster. The paper focuses on the ​​applicability of simulation software as an effective Industry 4.0 tool in the area of ​​real conditions of existing production. The company under study is planning a significant expansion of production. Still, before physically interfering with the existing production, it would like to verify the effects of the selected type of innovation. To create a reliable simulation model, it is necessary to map the current production process and collect relevant data. Subsequently, it is necessary to create a digital model of current production and gradually expand it with new factors that the company plans to implement in the future.
