## 6 Conclusions  
As observed by the current study, the application of advanced technologies (IoT, Cloud Systems, Big Data, robotics, etc. ), should focus on critical conditions and operations, collaboration, and talent development. This allows logistics companies to streamline their operations, reduce costs, improve overall performance, and ultimately gain the coveted competitive advantage. An approach based on critical business conditions and steps is necessary, and enterprises must prioritize the preliminary stage and the overall readiness perfectly captured through these critical stages in order to successfully enter the Industry 4.0 era and build trust with customers, employees, and partners. As found by the literature research, all the activity of the transition to the era of Industry 4.0 mainly goes through the philosophy of business model innovation, digital transformation, Quality 4.0, human resource management, and the shift to the new generation of logistics--Logistics 4.0. However, the journey towards innovation is by no means an easy task. Industry 4.0 technologies create, in addition to significant development opportunities, several concerns and challenges for logistics companies. In this context, innovation is more about steps and business conditions and not so much about technologies or manufacturing innovative products. For businesses to fully realize these benefits. they must be prepared to adapt their organizational culture, embrace change, and invest in the necessary resources. As can be seen, the present research is not exempt from limitations. Starting from the first limitation identified in the creation of the search strings, after the preliminary research of the literature and the search of the functions in business models based on Industry 4.0 in the logistics industry, the search strings that prevailed were \"Innovative business models in Industry 4.0\", \"Digital Transformation in Industry 4.0\", \"Human Resources in Industry 4.0\", \"Quality in Industry 4.0\", and \"Logistics 4.0\". At the same time, the second limitation is found in the selection of journal publishers, dates of publication, and the language of publication in which English prevails, excluding papers that were in other languages. In this context, it was decided to consider only papers from reputable publishing houses of well-known journals with a high index of academic and research credibility. The main contribution of the present study concerns the identification of the research direction captured by the literature review process. Business-critical requirements and Industry 4.0 architecture are now at the forefront of logistics, proving the key role they play in modernizing an organization and gaining a competitive advantage in today's globalized environment. At the same time, the present study provides a framework for practical and theoretical contributions. The practical contribution concerns logistics companies, as it indicates a structure in which they should clarify that it is not enough to only invest in technologies derived from Industry 4.0 to bring them to the fore, but they should first identify the concerns--obstacles that concern both the internal and external environment--and then invest significantly in the critical conditions to finally take full advantage of the advantages of these technologies. The theoretical contribution offers a comprehensive analysis of the existing literature on the research field under study, indicating the importance and necessity of the critical steps and conditions in the field of logistics and the general presentation of the most critical decisions to be taken into account during the introduction phase of the Industrial age 4.0, in a consolidated bibliographic context, as well as with reference to the main concerns and reflections. Future research in this area should focus on addressing the challenges and opportunities identified in this study.
