4.1 Structural Models

Structural modeling approaches are important for model-based systems engineering (MBSE), as they allow for the representation of the basic configuration and connections in complex systems (Friedenthal et al. 2014). They are essential for building clear, complete, and organized models that help in system design, analysis, and communication between all parties involved.

As illustrated in Figure 2.1 (Chapter 2), structural models in MBSE show the main parts of a system, such as its components, connections, and layered structure. They offer a straightforward representation of what the system is made of, helping engineers to better manage complexity.

4.1.1 Purposes and Benefits

Structural models provide several key benefits in MBSE processes:

• Complexity Management: By breaking down complex systems into manageable components and relationships, structural models help engineers handle intricate system architectures.
• Improved Communication: These models serve as a common reference point for diverse stakeholders, enhancing understanding and reducing misinterpretations.
• Consistency and Traceability: Structural models ensure consistency across different system views and enable traceability between system elements and requirements.
• Design Optimization: By providing a clear view of system structure, these models facilitate the identification of design improvements and optimizations.
