Leveraging SysML V2 for Integration of MBSE and Multidisciplinary System Development

Abstract

Model-based systems engineering (MBSE) is increasingly being used for the design and development of complex systems. An MBSE approach can create a cohesive model of the system architecture and integrate various aspects of the design. A key component of formulating an MBSE approach is having the capability to specify and express fundamental concepts about the system, and a systems modeling language gives that capability. In the past, Systems Modeling Language (SysML) has been widely implemented as an enabler of MBSE. However, several limitations of SysML have become apparent over the years that could not be resolved through simple revisions alone, so SysML v2 is under development. The primary limitation of SysML that this paper will address is the lack of interactivity and interoperability, which limits the ability to perform multidisciplinary analysis using the SysML model as input. This limitation has been alleviated using software solutions with SysML; however, the solutions are not guaranteed work together. This paper will evaluate the new innovations of SysML v2 with the primary emphasis on the new standard API and sophisticated textual language for enhancing interactivity and interoperability, especially with analysis tools, and propose a framework for leveraging these new capabilities in the design of a novel, hydrogen-powered aircraft. Development of this framework enables the automatic capture of decision-making based on new analysis or changes in requirements to update the system model and creates a method for coupling MBSE and MDAO activities.
