Using MBSE for the Operational Analysis of Systems

Last year, I wrote that one of the most important characteristics of a strong systems engineering organization is knowing the operational setting in which the system-under-development will be placed. (See: 9 Characteristics of Good Systems Engineering.) Whether you are an organization contemplating a new system initiative or product development, or …

MBSE: System Models, Executable Models, and More

When engineers speak about model-based systems engineering, or MBSE, the term “model” is used in many ways. Unfortunately, this only creates confusion between systems engineers, modeling and simulation engineers, and detail engineers. We all use models, so does this mean we’re now model-based? No. Remember that MBSE was devised as …

Systems Thinking: Schemas, Metamodels, and MBSE

“Metamodel” and “schema” are terms that get thrown around when we talk about systems and modeling of systems. But what do they really mean? “Meta” comes from the Greek and literally means “above” or “beyond,” but has also come to mean “about” or “of,” so a metamodel is a model …
