## 2 Literature Review of the Analyzed Problem  
In the available literature on process modelling and simulation, many items that explain this issue and indicate its various aspects can be found [15]. Many papers present the application of a particular method or software along with the results obtained by a specific researcher. The first research focused on the theoretical aspects of simulation and modelling. The paper [16] contains definitions of modelling and illustrates the advantages and disadvantages of using this tool to investigate potential solutions. Reference [17] focuses on the issue of model construction. The authors indicate the purpose of modelling, methods of implementation and stages of its preparation [18]. The next analyzed items present the stages of building a simulation model with the use of computer software [19]. This is an extremely important issue because in today's production environment, this solution is widely used due to the significant complexity of the systems operating in enterprises. In [20], the authors developed one of the most important elements of model building, which is validation. It is of key importance in system analysis because it is used to check the correctness of the implemented project, which translates into the reliability of the results obtained [21]. In addition, this study provides information on the areas of application of simulation modelling and then presents the issue of using this tool in the aspect of production process management [22]. In Ref. [23], simulation models are divided according to their characteristics. Other studies [24] focused on the use of this tool in companies producing a particular product. They present individual production areas in which simulation modelling can be used and describe the stages of production preparation based on simulation models. They describe the methods of analysis of the functioning system through the selection of an appropriate tool and the implications of the results obtained in the real production environment. In a narrower approach to simulation tools, researchers focus on issues related to the modelling and simulation of production processes themselves. In some articles [6], the authors present the course of the work and the analysis of the results obtained using the ARENA software (c 2024 Rockwell Automation [7]. However, reference [8] focuses the authors' attention on the mathematical aspects of building models. Simulation methods are presented here as well as an experiment illustrating how the results obtained should be considered. Production processes are complex and multi-stage activities, consisting of various tasks and phases [25]. However, the organization of processes in the conditions of dynamic changes occurring in a company's environment is very difficult and problematic, because in order to maintain the continuity of the production process, work must be properly designed and rationally organized [26]. Another researcher emphasizes that, currently, the availability of new digital technologies shapes the business environment of enterprises and creates new opportunities for development by introducing innovations to the structures within Industry 4.0 [27]. These innovations refer to the possibility of blurring the boundaries between physical and virtual entities [28]. Digitalization is forcing traditional industrial organizations to rethink and develop existing business models [29]. Modelling connections between operations and analyzing real scenarios for a given process, taking into account the internal and external environment of the enterprise, is possible using computer simulations and specialized tools [30]. Solving various technical problems using simulation modelling is effective, and its effectiveness has been confirmed, among others [31], in the research of one of the authors [32]. Other studies [33] show that a properly designed production process can reduce operating costs in a company by up to 50%.
