MBSE (Model Based Systems Engineering) is a model-centric approach providing a single point of truth which is reflected in a set of living artefacts.
MBSE is a term that predicates the use of modelling to analyze and document key aspects of the Systems Engineering Lifecycle. It is broad in scope, spanning the SE lifecycle and covering levels from System of Systems to individual components.
Model Based Systems Engineering is a multi-disciplinary approach with the goal to develop a balanced system solution in response to various stakeholders’ needs.
MBSE helps the engineer to keep track of complex systems – to understand the context and the specification – in order to be able to fulfill all defined requirements. While traditional methods of systems engineering are paper or document based, the MBSE design process based on digital models. This allows for a better handling of complexity and facilitates information exchange among disciplines.
Modeling languages introduce a model-based specification of a product on a general level that is understandable for all disciplines involved in the development. The current problems with integration of components during the development process can be addressed as early as possible through the use of such modeling languages by defining correlations between system requirements, functions, structure and behavior.
Moreover, in today’s enterprises the accumulated data during the development process is usually managed in Product Lifecycle Management (PLM) solutions, so that only an integration of a functional product description in PLM can support the interdisciplinary collaboration at an early design stage.
MBSE has taken center stage in many different areas including the Department of Defense (DoD). In fact, some would say that the MBSE initiative developed and championed by the Office of the Deputy Assistant Secretary of Defense (ODASD) has been a wake-up call for (DoD).
The initiative asserts that digital engineering has the potential to promote greater efficiency and coherence in defense programs by ensuring stakeholders have access to accurate, relevant, and consistent information throughout the life of a program.
The intent of the initiative is that by developing and maturing a digital representation of that system and how it interacts with its environment will go a long way in delivering relevant trainers from the outset. This as opposed to previous simulators with inaccurate threat environment or without the latest software update.
It’s also believed that digital representation will help DoD with sustainment efforts throughout the life of the program. Models, of course, can help show how the system would hold up over time and in different environments.
