Some background how MB attempts to keep up with increasing design complexity.
Smaragd-based engineering at Daimler
Interview with Prof. Alfred Katzenbach, Director of IT Management at Mercedes-Benz Cars Research and Development.
Professor Katzenbach, what do you expect the global deployment of Smaragd to deliver? What are the key performance indicators?
Let me answer that question from the user’s perspective. Smaragd must be available around the clock and deliver extremely rapid response times. This is because every component used in vehicle development has to have a corresponding data record. Smaragd is our core engineering backbone system. It manages all our design data, and provides our developers worldwide with a single view of the truth.
Who has access to Smaragd and its data?
In addition to the 8,000 engineers who own the data, there are many more who use it – from designers, to staff at our production facilities, to members of the executive board.
And the solution increases the efficiency of your engineering workflows in product development?
Constantly: for example, by helping us avoid iterations, and keep data consistent and free of redundancies. The solution allows us to synchronize parallel processes, accelerate individual development phases, and better predict results.
Predict results: what does that mean, exactly?
Smaragd enables us to perform simulations in virtual reality. As a result, we can accelerate prototype development, reducing the need for physical prototypes and mockups. The first digital we create is now considerably more advanced than in the past. But ultimately, we have to fine-tune the handling, comfort and user-friendliness on the real-world car. Perfecting a Mercedes involves hands-on driving on real roads. And that will still be true a hundred years from now.
Where is Smaragd deployed?
It is used for all our vehicles: in other words, for cars, buses, vans and trucks made under the Mercedes, smart, Maybach, Fuso and Freightliner brands. This applies to every model on the market or in development. During the strategy, prototyping, and production phases, we integrate the virtual world into the development cycle and accelerate each individual stage: from design, to flow simulations, interior design, ergonomics, crash testing, fuel-economy optimization, and production.
What are the key success factors?
Developing a vehicle is an optimization task involving multiple criteria, with interdependencies between processes in different disciplines. So the ability to promptly sign-off every single step in the development process is a key success factor. This is particularly true in design and engineering. At the approval stage, which hundreds of components reach every day, we use Smaragd’s integrated approval processes to get the green light and legally binding sign-off (for product liability purposes) from everyone responsible for the components.
Once the car is in production, Smaragd’s job is done, isn’t it?
Actually, it’s not. You could say Smaragd always plays a part. For example, at the vehicle planning stage, we digitally simulate the installation and removal of parts during maintenance and repairs. This helps us create solutions that later minimize the duration and cost of visits to the repair shop.
