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 …

“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 …

We all understand that our complicated world is giving way to a more complex one. We also recognize that our systems engineering techniques used to create modular designs are breaking down as we deal with new levels of complexity. It seems we don’t talk so much about modularity and its …

Milestones are great times to stop and acknowledge where you’ve been and where you’re going. This past week, on Tuesday, August 13th, Vitech celebrated 27 years of being in business. We’re more than a little proud of all we’ve accomplished in our first little-more-than-a-quarter century, and are looking forward to …
