A SysML V2-Based Framework for Multi-Disciplinary System Virtual Integration

In the automotive industry, as market demands continue to grow, the complexity of vehicle systems has been increasing accordingly. Vehicle manufacturers are thus confronted with the challenge of offering more design options. Model-Based Systems Engineering (MBSE) has been introduced to manage the complexity of product development. Meanwhile, its integration with Multidisciplinary Design Analysis and Optimization (MDAO) provides a harmonized methodology for the design and analysis of complex systems, offering a system-level virtual integration environment to support decision-making processes. However, current MBSE modeling languages such as SysML v1.x are extensions of the graphical modeling language UML and are considered semi-formal. Their limited capability to extend and integrate with modeling languages across different disciplines significantly restricts their effectiveness. SysML v2, built upon the formal modeling language KerML and supporting standardized APIs, enhances model interoperability. By utilizing SysML v2 to develop a domain-specific modeling language tailored for multidisciplinary engineering, it becomes possible to effectively maintain data consistency between system design and analysis processes, establish a virtual integration platform, and ensure interoperability with other environments. This paper presents a SysML v2-based multidisciplinary system virtual integration framework, implemented by constructing a coupled multidisciplinary problem model in the context of automotive systems.
