New videos on the PRFC YouTube channel!!

Cet article parle de : , , ,

The PRFC YouTube channel on MBSE has been in existence for 18 months now …

We now have nearly 300 subscribers, but more important a dozen videos (in French and in English), with more than 10,000 views, and 675 hours of viewing 😉

The most popular video is without context the one in French entitled: Introduction au MBSE avec Arcadia et Capella, with over 2250 views and 200 hours of viewing time.

A newer and more technical video in English: Blank Diagram Basics in Capella, still had over 1,400 views and 80 hours of viewing. And we’ve just added two new videos on the Scenario Diagram, one of the trickiest to master in all modeling tools, UML and SysML included:

These videos are all short extracts from recent remote training courses, and prefigure the library of e-learning modules that we are going to produce in the coming months. They will be supplemented with quizzes, resources, etc. which will be available to PRFC customers. In short, our ambition is to build a complete ‘blended-learning’ offer on MBSE around Arcadia / Capella next year …

Stay tuned and subscribe!


Summer Remote Session of “Capella in Action”!

Cet article parle de : , , , ,

If you don’t speak French, or do not want to travel to Toulouse ;-), but you still wish to get trained on Arcadia/Capella, a remote session in English is scheduled from August 18 to 21. It will consist of 7 sessions of 3,5 hours (9:30-13:00; 14:00 -17:30) from Tuesday to Friday morning, through the zoom platform. But take care, there are already only 2 places left …

We take this opportunity to offer a discounted summer rate: €1,990 instead of €2,390 for the complete training. Note: the second registrant from the same company benefits from an even lower price at €1,690 instead of €1,990.


Launch of the PRFC YouTube channel on MBSE!

As noted in a previous post, PRFC switched its MBSE training offer into remote sessions throughout the confinement period and until summer.

To continue in this direction, next to videos in French, we have just published a first public video in English on the brand new PRFC YouTube channel:

This video (and future ones) is a short extract from a one-day training course, and prefigures the library of e-learning modules that we are going to produce.

They will be supplemented with quizzes, crosswords, etc. which will be available to PRFC customers.

In short, our ambition is to build a complete ‘blended-learning’ offer on MBSE around Arcadia / Capella and SysML in the coming months …

Stay tuned and subscribe!


MBSE ‘Remote’ Training Sessions in May

Cet article parle de : , , , ,

As mentioned in a previous post, PRFC switches its MBSE Training offer to remote sessions throughout the confinement period and until the summer. Do not hesitate to contact us for any intra-company training quote.

For the month of May, we are organizing three one-day MBSE introductory sessions.

One of them will be conducted in English:

MBSE remote Training with PRFC!

Cet article parle de : , , , ,

In this period of confinement and teleworking, the training activity is still relevant, and even more so!

PRFC offers you to carry out remotely all the MBSE training courses corresponding to the new Training Offer for 2020.

For sessions without tool manipulation, arranged under the categories:

  • Seminar ‘Introduction’ in 1 day;
  • Workshop ‘Through practice’ in 2 days;

We will continue to offer them on an inter-company basis, thanks to platforms like zoom or Teams.

Thus, the inter-company session of April 21 concerning the one-day training: MBSE with Arcadia is maintained and will be moderated remotely by Pascal Roques (in French).

Another session will be conducted in English on April 30 by Pascal Roques.

For intra-company sessions, we also offer to carry them out remotely via your preferred platform. Regarding the longer training sessions with tools on Capella and SysML with EA or CSM, they will be run in smaller groups, to ensure sufficient interactivity when handling modeling tools.

Intra-company scheduling can also be much more flexible, since we will plan with you a number of 3.5-hour sessions, not necessarily consecutive, depending on the needs of each client and the requirements of the participants

Do not hesitate to contact us to define together the most suitable modern training solution possible!


PRFC Training Offer for 2020

Cet article parle de : , , ,

PRFC training offer is reorganizing for 2020!

We of course still offer trainings on MBSE (Model-Based Systems Engineering) around two main streams:

And we can organize training sessions either:

  • In-House on customer site, on demand, with possibility of customization;
  • In inter-companies in Toulouse and Paris, from the PRFC standard catalog;
  • Remotely, through platforms like zoom ou Teams.

Our new trainings are progressive, according to your objectives:

  • Seminar ‘Introduction’ in 1 day: presentation of MBSE with commented examples
  • Workshop ‘Through practice’ in 2 days: use of a modeling language on a paper case study
  • Hands-on workshop ‘In action with the tool …’ in 3 or 4 days: use of a modeling language on a case study with a modeling tool

The PRFC website will be progressively updated, with new training sheets, and we will soon be offering inter-company sessions in Toulouse and Paris!

In the meantime, here is already the declination of the offer on both streams:


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 😉 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 ​​…

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.

Happy New Year 2019!

PRFC wishes you the best for 2019, with the implementation of an effective MBSE approach!

Let us do a quick review of 2018 from our side.

2019 seems to start on the same basis with already several Arcadia / Capella courses scheduled on customer site in France, Germany and the United Kingdom …

PRFC was at the MODELS 2018 conference in Copenhagen

Cet article parle de : , , , ,

PRFC had the pleasure of participating once again in the annual MODELS conference (cf. St Malo in 2016) organized this year in the beautiful city of Copenhagen.

20 years already that the first edition, called UML’98, was held in Mulhouse, organized by Pierre-Alain Muller!

To note the significantly more important part of industrial participants than in the past, which is a very good sign for a conference on modeling!

I was mostly interested in the Model-Based Systems Engineering Meeting and in the Industry Day.

The MBSE Meeting started with a very interesting keynote of Ed Seidewitz: SysML v2 and MBSE: The next ten years, Basically the main problem of SysML is its direct filiation with UML… Room for Arcadia/Capella:-)

Then we had a large number of industrial presentations on the MBSE Adoption Challenges:



The next day, a lot of people in the big Amphi for The Industry Day with some well-known presenters:

As always, diverse and rewarding encounters and an appointment made in September next year at Munich for MODELS 2019!

Arcadia is a French Standard (AFNOR)!

Cet article parle de : ,

The ARCADIA method has been standardized with the AFNOR as Experimental Standard Z67-140, by the ‘Engineering and Quality of Software and Systems’ commission:

Technologies de l’information – ARCADIA – Méthode pour l’ingénierie des systèmes soutenue par son langage de modélisation conceptuel – Description Générale – Spécification de la méthode de définition de l’ingénierie et du langage de modélisation

The summary of this standard is as follows:

  1. Scope
  2. Terms and definitions
  3. Specification of the ARCADIA engineering definition method
  4. General specification of the ARCADIA modeling language
  5. Specification of ARCADIA modeling language concepts
  6. Annex A (informative) Description of the ARCADIA method
  7. Annex B (normative) ARCADIA concepts and perspectives
  8. Annex C (normative) Relationship between concepts

The document XP Z67-140 was published (in French) in March 2018. It is on sale on the AFNOR shop.

Note: ARCML is the name of the modeling language dedicated to the definition of models that conform to the ARCADIA method.
