Update of the Clock Radio Capella Model (start)

During my SysML trainings, I have been using for several years now a simple example of a system: the Clock Radio. This is even the main example of my SysML introductory book in French, published by Eyrolles in 2013.

As part of the Clarity project, it seemed natural to do the same exercise with Capella using the Arcadia approach and concepts. I published in 2015 a first version of the model (with Capella 1.0) where I concentrated on the System Analysis level, trying to illustrate the main types of diagrams, but also ensuring the traceability with the operational need expressed in Operational Analysis. Then a second version of the model, with the Logical Architecture level. And finally a third version of the model with the Physical Architecture level and a small example of Viewpoint: Basic Price.

It was high time to update this model, trying to illustrate the new features provided by Capella 1.2.1 and now Capella 1.3.

The first version of the new model is downloadable here. It mainly contains the System Analysis level, because the operational need is very simple ūüėČ You will find examples of SMCB, SAB, SCDB, SES, SMSM, with several variations of each.

The progressive construction of the model is presented in a small explanatory document. The model and its companion document will be progressively completed with a Logical Architecture level, a Physical Architecture level, then the use of the Requirements add-on and of Property Values ‚Äč‚Äč…

An example of Exchange Scenario Diagram that was not possible before Capella 1.2.1 is given below. This is a scenario showing how two instances of the same User actor can interact with the Clock Radio.

An expanded MBSE training offer for 2018!

Cet article parle de : , , , , ,
The¬†MBSE training offer will become richer and more modular in 2018, distinguishing better from one side ‘Language & Method’, and the other ‘Tool’, with two major streams:
The general scheme is as follows:
  • MBSE with XX¬†training contains 66% theory and 33% group reflection on a case study (without tool)
  • YY in Action training contains instead 75% of practice (with a modeling tool) and 25% of theory illustrated with examples

MBSE with XX training is a strongly recommended prerequisite of the corresponding training YY in Action.

 

This new scheme will enable to gradually enrich the offer with new modules, such as:

 

 

 

or:

PRFC was at ERTS 2018

Cet article parle de : , , , , ,

I had the pleasure of attending last week the 9th ERTS2 conférence.

This big event around ‘Embedded Real Time Software & Systems’ takes place every 2 years in Toulouse. This year there were more than 300 registrants from a very large number of companies, with a particular focus on the automotive industry and mainly the autonomous vehicle. Exciting keynotes from Renault and Airbus on the subject …

I took part in the presentations by co-animating with Benoit Viaud (Artal) a session on MBSE entitled Capella to SysML Bridge: a Tooled-up Methodology for MBSE Interoperability with work done within the framework of the Clarity project, and of course I was not far from the Capella stand!
