Table 3: Results of the DEMADEL MCDM analysis. Figure 9: Graphical illustration of the DEMADEL MCDM analysis results. to the graph, it can be seen that factor g9 has the greatest impact on the implementation process. This factor is integral during the implementation of the components of Industry 4.0, this is explained by the fact that technologies are developing very quickly and so is the software. DEMATEL MCDM method is based on the assessment of the influence of factors on one another and therefore, it is important to find not only the most influential factors but also to emphasize their relationship. To draw up a diagram of the influence of factors on each other, it is worth referring to the Table 4.  
Figure 10 shows that not only g9 factor is important (Figure 9) but g8 is important too. This can be explained by the fact that with the development of technology, the area of collected and processed data is constantly expanding, which entails changes in legislation, as well as the facts of the adoption of legal restrictions on the use of powerful computers, which have increased power consumption [42], etc. Laws affect the very development of technology and technology, as well as the emergence of the Industry 5.0 trend. In the case of the studied enterprise and SMEs in general, it can be said that mobile applications and devices are the keys to the implementation of Industry 4.0, but one should not forget to take into account external factors of influence during vertical and horizontal integration. According to the results of the study, it can be stated that mobile applications can be used as a tool for adapting to modern technologies and offered cycles (Figure 1) and methods of evaluation could be useful for other enterprises in the manufacturing branch. The proposed cycle of innovations will ensure sustainable development of the enterprise, since even highly automated manufacturing plants involve people in one way or another, and it is especially important to ensure that they adapt to the proposed changes. Mobile applications, due to their wide functionality, can be used as a tool for vertical and horizontal integration of Industry 4.0 components into the manufacturing process.
