[caption id="" align="alignright" width="288" caption="Location of Graz Symposium Virtual Vehicle Development (Casino Congress)"][/caption] 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 the three points. I'd like to proceed the discussion here in the blog and hope that I'll...

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 a comprehensive system model. MBSE is definitely an enabler for the virtual vehicle and essential for the automotive industry to handle the incredible challenges they were...

A message from the  INCOSE Telescope modeling challenge team: The INCOSE Telescope modeling challenge team releases version 1.1. of its MBSE plugin for MagicDraw with SysML: https://sourceforge.net/projects/mbse4md/ Support for more productive Model Based Systems Engineering, following the recommendations in the Cookbook of the INCOSE SE2 Challenge team. The Plugin for the MagicDraw modelling tool provides support for model based document generation which ties together system model and documents to keep them up to date and consistent, using a AWYSIWYG editor in MagicDraw. It provides basic...

Since a few months I work on the next edition of my MBSE book "Systems Engineering with SysML/UML". I plan to publish it in the first quarter of 2013. It'll be the third edition of my German version. So far I have no plans for the English version of the book. New content will be: Updates to the MBSE process SYSMOD SysML 1.3 or SysML 1.4 Preparation guide for the OMG Certified Systems Modeling Professional certification exam (OCSMP) Alignment with my upcoming book about system...

The newest version 1.3 of the SysML will be published in a few weeks. The development of the version 1.3 already finished last year and we currently work on the next version 1.4. I'll report on the work for the 1.4 version in a separate post in the near future. Typically the dot versions of SysML contain only minor changes. Anyhow the SysML 1.3 comes with many changes in the area of ports. The basic concept is still the same. There...

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 relationships SysML provides the callout notation. A comment symbol is attached to the state or action or to any other element in the state machine/activity diagram. The...

NoMagic provides a free SYSMOD plugin for MagicDraw (see Download page). NoMagic just released SysML version 17.0.1 SP2 with the following updates for the SYSMOD plugin: The New SYSMOD profile version is now with enhanced variants modeling support (See CarAccessSystem example model). The message box stating that the SYSMOD plugin should be installed will no longer be shown after loading the existing SYSMOD projects. The «Functional block» stereotype has been removed from the new SYSMOD profile to avoid conflicts with the new FAS plugin...

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 SysML and the model elements Block (for the system) and Actor (for the users and external systems). By definition, the model element Actor represents an...

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 a book about MBSE with SysML, parts of the SysML specification and several papers. These are static unidirectional medias. I like to talk about MBSE in...
