The fifth part of the blogpost series about the changes in SysML 1.4 presents the updated concept of units. But first a big sorry for being quiet for such a long time. But better be quiet than posting spam. I hadn’t enough time to continue my series about the news and updates of SysML 1.4 as well as other interesting things for the MBSE community. The reason for my absence was one of those interesting things: I was on the final spurt...

End of this week is the deadline for the Call for Presenters for the 3rd Nordic Systems Engineering Tour. Share your knowledge and join the tour. The NoSE Tour is a non-commercial community event organized by four local chapters of INCOSE. It is a 1-day conference traveling from Hamburg to Copenhagen via Stockholm to Helsinki. Find more information about the tour on the official website: www.nordic-systems-engineering-tour.com. Reports from the last tours NoSE 2013 and NoSE 2014. See you, Tim ...

The fourth part of the blogpost series about the changes in SysML 1.4 presents the new concept to constrain a decomposition hierarchy. The following figure shows a simple product tree of a drone subsystem (DS) for a forest fire detection system (FFDS). It is the sample system I've also used in some previous posts.

The third part of the blogpost series about the changes in SysML 1.4 presents the updated concept of view and viewpoints. View and Viewpoint are model elements of SysML since the very first public version 1.0. As you may know SysML was developed based on a request for proposal with a set of requirements. One requirement was about views: [caption id="attachment_836" align="aligncenter" width="762"] SysML 1.4 - View and Viewpoint - Requirement (click to enlarge)[/caption] In SysML 1.0 the view and viewpoint concept...

The second part of the blogpost series about the changes in SysML 1.4 presents the new concept to group elements. The use case is simple: Create a group of model elements: [caption id="attachment_820" align="aligncenter" width="300"] SysML 1.4 ElementGroup Use cases (click to enlarge)[/caption] Okay, on the second thought there are some more: Update a group and Delete a group. And I’m sure that you’ll find some more use cases on the third thought. It also depends on your personal definition of a use...

We are still waiting for the official release of the SysML version 1.4. The work on the update already finished several months ago. Due to some organization obstacles the official release is delayed. In April 2014 the OMG published a beta version of the SysML 1.4 and some tool vendors already published updates of their modeling tools with SysML 1.4. You can find the SysML 1.4 beta specification on the SysML specification website. So it is time to report about the...

My publisher just released the third edition of my book "Systems Engineering with SysML/UML". To be exact it is the German version of my book "Systems Engineering mit SysML/UML". Since the second edition 6 years have passed. In this time the language SysML, my MBSE methodology SYSMOD and MBSE in general have been further developed. The media book could hardly follow the high dynamics that currently happens in our engineering environment. Extremely spoken the book is outdated when it leaves the...

What a great week! Summer, Fun, Great Cities and Systems Engineering. The 2nd Nordic Systems Engineering Tour from Hamburg via Copenhagen and Stockholm to Helsinki has just finished. Four tour speakers who did the whole tour and several local speaker gave great performances and shared their knowledge and experience with nearly 200 participants. And vice versa during the discussions participants gave an insight to their knowledge and experience. I've learned a lot! The NoSE Tour is a non-commercial event organized by four...

The Program is online, the registration is open – we are looking forward to see you in Hamburg, Copenhagen, Stockholm or Helsinki. Register here! The 2nd Nordic Systems Engineering Tour 2014 starts May 20th in Hamburg and ends May 23rd in Helsinki. At each venue we provide a one-day conference with great speakers and time for networking. It is not a commercial event. It’s organized by four local chapters of INCOSE and our objective is to strengthen systems engineering and the...
