As a prime systems integrator, BAE Systems develops and sustains a large array of complex mission critical systems throughout their lifecycles and uses a broad range of engineering modeling and design tools across multiple engineering disciplines.
To help us deliver the best possible solutions and services for our U.S. government customers, we use a Model Based Systems Engineering (MBSE) approach to digital engineering, which transforms legacy, document-based development stovepipes into a product-centric, integrated, digital enterprise. Built on a model-based, integrated development or data environment, a digital enterprise supports multi-disciplinary, multi-organizational stakeholders and leverages product-line reference architectures and a shared model library to develop, deliver, and sustain a system through its lifecycle. We believe the application of MBSE tailored to the nature of the specific mission and unique requirements of our customers supports and improves acquisition, operations, performance, and system lifecycle sustainment.
Value of MBSE
Rather than using traditional document-based data through the systems engineering and systems integration life cycle, MBSE uses models and simulations as the primary means of information exchange and to create digital threads and “digital twins” for systems. MBSE’s integrated data set approach:
- Improves system quality, consistency and digital traceability
- Increases personnel productivity and efficiency
- Early risk identification, ,cost reduction, schedule and performance improvement
- Enhances communications across key stakeholder groups
- Eliminates single point failures through collaboration, knowledge sharing, and the exchange of models and their underlying data
MBSE in Action
BAE Systems has successfully applied MBSE to existing U.S. Department of Defense (DoD) programs and new acquisitions containing complex interdependencies. Some examples of our MBSE approach:
- We’ve used our expertise to translate “paper-based” legacy and heritage design documents, for the U.S. Air Force Intercontinental Ballistic Missile (ICBM) Program, into interconnected, cross-domain digital models that “own” constantly evolving technical baselines.
- Our model-based test and evaluation (T&E) approach for Independent Verification and Validation (IV&V) applied to the U.S. Navy AEGIS Technical Representative Program uses system models to manage the requirement baseline and architecture traceability, change impact analysis, verification testing, and to automate the system and software testing process.
- Our Digital Engineering Classified Lab (DECL) provides an Integrated Data Environment (IDE) in for the weapons system technical baseline. We use state-of-the-art Artificial Intelligence and Machine Learning (AI/ML) technology to deliver connected, immersive visualizations that mimics real world systems and provides the ultimate interactive customer experience to support collaborative engineering, paperless critical design reviews, software architecture and hardware design decision-making.
