Acronyms can be challenging when entering a new engineering discipline, and model-based systems engineering (MBSE) is no exception. In the case of MBSE, numerous acronyms can look very similar, adding to the challenge. It turns out that many of the confusing acronyms are related to software development, not system engineering. That’s because MBSE began as […]
How does object-oriented systems engineering relate to MBSE?
The object-oriented systems engineering method (OOSEM), sometimes referred to as object-oriented systems engineering (OOSE), is a systems-level development method from the Object Management Group (OMG) that combines object-oriented concepts with traditional systems engineering practices. It leverages concepts originally used in object-oriented software development and applies them to systems engineering. This FAQ starts with a review […]
How can MBSE be used in autonomous transportation?
One of the primary uses for model-based systems engineering (MBSE) is the design of complex cyber-physical systems and systems of systems. Autonomous transportation certainly qualifies for that description. MBSE replaces the traditional document-based system engineering process with linked models to represent and analyze systems. The use of MBSE with aircraft and spacecraft is the subject […]
How do SDLC and MLM relate to MBSE?
Depending on the context, SDLC can stand for system development or software development lifecycle. In model base system engineering, the SDLC (sometimes called the Application Development Lifecycle, ADLC) is a multi-stage process for planning, creating, testing, and deploying a system, including requirement analysis, design, development and testing, implementation, documentation, and evaluation. Model lifecycle management (MLM) […]
How do SPDM & PLM support MBSE?
Simulation process and data management (SPDM) is a software tool that manages simulation processes and data across the enterprise and the product lifecycle. In MBSE, SPDM can be used to help build and maintain the digital thread. SPDM provides traceability. It’s related to product lifecycle management (PLM). PLM provides a database for all information related […]
What are the nuances of a good MBSE model?
Model-based systems engineering (MBSE) is a digital modeling approach to the conceptualization, specification, design, verification, and production of cyber-physical systems and systems of systems. In MBSE, models replace the massive paper-based documentation that was the basis of previous systems engineering (SE) approaches. The model provides a single point of truth for all the design and […]
How do MIL, SIL, PIL and HIL simulation and testing relate to MBSE?
Model-based systems engineering (MBSE) supports requirements development, design, analysis, verification, and validation of complex systems, especially cyber-physical systems and systems of systems. Verification (simulation) and validation (testing) are key elements of MBSE. Model in the loop (MIL), software in the loop (SIL), processor in the loop (PIL), and hardware in the loop (HIL) simulation and […]
What’s a digital shadow and how does it relate to a digital twin?
Depending on how they are used, digital shadows take different forms and can be created using different techniques. Digital twins, on the other hand, have a specific definition within model-based systems engineering (MBSE): a virtual representation of a device or system that spans its life cycle, from initial conceptualization and specification through end of life, […]
How do the military and aerospace use MBSE?
Model-based systems engineering (MBSE) is broadly defined as the structured use of digital modeling to support system features, requirements, design, verification, and validation extending from the conceptual design phase and continuing until end of life. The concept of systems engineering is deeply engrained in the military and aerospace communities. MBSE represents a shift from highly […]
How do SysML and model-based design relate to MBSE?
Model based design (MBD) is not a new concept; it’s been successfully applied to complex software systems for many years. MBD is often implemented using the unified modeling language (UML) for software development from the Object Management Group (OMG). Extending the concepts of MBD to cyber-physical systems, including both software and hardware, is a relatively […]
