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 …
