Problems, introduction and opportunities of MBSE

In my last post I’ve reported from my visit of the Graz Symposium Virtual Vehicle Development. In my workshop at the symposium I asked the participants about the problems that are solved by MBSE. what must be done/what we need to introduce MBSE in the organization. the opportunities of MBSE. We had very interesting discussions about…

MBSE meets Virtual Vehicle Development

Virtual Vehicle development is an exciting new technology. This week I’ve visited the 5th Graz Symposium Virtual Vehicle in Graz (Austria). I was very impressed by the engineering methods & tools that were already reality. An important missing link for the virtual vehicle development is the combination of all the single models and simulations in…

I’ve just found this question in a sysml discussion forum: Is it really not possible to place requirements objects on an Activity, State Machine, or several other similar behavioral diagrams? Yes, it is not allowed to put requirement elements on a state machine or activity diagram. Since it is essential to show such cross cutting…

The SYSMOD Zigzag Pattern

Are your requirements really free of any solution? Requirements describe the What, the system architecture describes the How. Sounds easy, but…. Requirements are solution-free and they contain solution aspects at the same time. It depends on the level of abstraction. Let’s assume that you have absolutely solution-free requirements (I argue that those requirements are not…

The Death of the Actor

The technical term System is relative and depends on the viewpoint. From one viewpoint an entity is a system, from another one it is a subsystem or an external system. It is a role that is applied to an entity. You loose this flexibility of changing the viewpoint if you model a system context with…

MBSE in a Blog

In many respects, the future of systems engineering can be said to be “model-based.” (INCOSE Vision 2020) Model Based Systems Engineering (MBSE) is a key technology to respond to the need of developing more and more complex systems in more and more complex (network) organizations. I work in the MBSE domain since 10 years. I’ve written…
