## 4 Results and Discussion
The principles of operating the infrastructure of industrial enterprises using BIM technology in conjunction with MBSE can be formulated as follows (in priority order):  
* Data integration and centralization: Create a common centralized information platform that combines data from BIM models and MBSE models to provide a single source of truth about the state of enterprise objects and systems. * Lifecycle Integration: Integrate design, construction, operations, and change management into a single cycle through consistent BIM and MBSE models to minimize switching between systems and reduce the risk of errors. * Full visibility and transparency: Ensure that up-to-date data and models are available to everyone involved in the project and operations, allowing you to quickly respond to changes and optimize processes. * Knowledge and Experience Management: Implement a BIM- and MBSE-based knowledge management system that allows you to retain and transfer knowledge about the design, construction, and operation to ensure business continuity. * Process Analysis and Optimization: Use BIM and MBSE to model and simulate processes in the enterprise to identify bottlenecks, optimize resources, and improve efficiency. * Risk Forecasting and Management: Use BIM- and MBSE-based analytical tools to anticipate operational risks and develop strategies and plans to manage them. * Collaboration and communication: Promote collaboration between different disciplines and project participants, using collaborative BIM and MBSE models as the basis for effective communication and collaboration. * Flexibility and adaptability: Create flexible BIM and MBSE structures that can adapt to changes in the requirements and conditions of the enterprise, ensuring the long-term sustainability of the system. * Staff training and development: Train staff to work with BIM and MBSE to maximize the potential of technology and provide skills for effective infrastructure management. * Regulatory Compliance: Maintain compliance with processes, data, and models to regulations and standards that ensure quality, safety, and industry compatibility. These principles will help provide a more integrated, efficient, and sustainable approach to managing the infrastructure of industrial enterprises using BIM and MBSE. The Figure 5 illustrates the place of BIM in digital transformation based on the interconnections between the physical and digital worlds. Based on the MBSE approach, IFI should be considered in terms of a number of requirements, functions, components (systems and subsystems in accordance with the construction information classifier), and processes. To identify relationships, the method involves the compilation of pairwise matrices RBS-FBS, RBS-PBS, RBS-WBS, FBS-PBS, FBS-WBS, and PBS-WBS. At the same time, it is proposed to distinguish the following entities in an enlarged way:  
* Requirements (RBS); Requirements for the reliability of structures;
* Functional requirements;
* Requirements for space-planning solutions;
* Cost requirements;
* Functions (FBS);
* Project Initiator (Investor-Owner/Order);
* Contractor;
* Contractor (Operation);
* Components (PBS);
* According to the Construction Information Classifier;
* Processes (WBS);
* Projection;
* Construction;
* Exploitation;
* Disposal (demolition). In industrial facility infrastructures (IFIs), which encompass both production and production infrastructure, digitalization involves the integration of Building Information Modeling (BIM) and digital twin (DT) technologies. The approach to maintaining buildings, structures, and life support systems via information modeling technologies centers on the creation of a digital asset--an enterprise's digital resource capable of generating economic benefits. This digital asset comprises a set of digitized requirements, functions, components, and processes. The proposed method aligns with Model-Based System Engineering (MBSE), an operated building that can be viewed as a complex technical system, often referred to as a \"system of systems\".
