Digital Fingerprint

Creating a basis for an intelligent value chain

Intelligent data collection, processing, and transfer along the entire value chain – from the idea, design, production and in-service to the end-of-life – for the intelligent component and the versatile, autonomous factory of the future!

Continuous data flow at any time

In order to realize this plan, a continuous data flow at any time and any process step is necessary. Context-related semantics are required so that the various data types can be correctly assigned at any time. Different disciplines exchange data and must always know where the data of the previous steps are and what exactly they mean.

Data must be stored and smartly linked

The basis is therefore the digital fingerprint of each component, which stores and smartly links all data from the initial concept, design, calculation, process, machine, logistics, and in-service from integrated sensors. The main objective of the digital fingerprint is thus the further development of a component into an Industry 4.0 component and the creation of the necessary basis for the intelligent value chain of a component for the future.

The digital fingerprint can consequently also be seen as a foundation for Industry 4.0 applications and accordingly as a link between all ARENA2036 joint projects.

Five subprojects lead to the realization of the project Digital Fingerprint

Subproject 1 (SP1) - "Data and Semantics" foregrounds the semantic description of the digital fingerprint.

In order to develop the intelligent component, different simulation approaches are considered in SP2 - "Smart Engineering", both for structural simulation and for optimization and process simulation.

To achieve the desired intelligence of the component, suitable sensors are integrated into the demonstrator in SP3 - "Smart Component" to obtain data from the manufacturing process as well as from the in-service area.

In SP4 - "Smart Production" the interface to production and assembly as well as to the neighboring project Fluid Production will be established.

In SP5 - "In Service and Evaluation" the evaluation of the digital fingerprint is done. For this purpose, the value chain of a component is run through at the beginning of the project according to the state of the art. This serves as a reference. At the end of the project, the newly developed interfaces and data semantics will be used to run through the value chain again and to compare it with the reference.

The result will be a flexible, expandable automated value chain that can be used as a basis in various fields of technology. In addition, new tools such as sensitive components and virtual evaluation methods will be available. The component is thus available as an Industry 4.0 component.

"ARENA2036 is a lighthouse of the University of Stuttgart in the field of knowledge and technology transfer. In cooperation with our partners from science and industry and not least start ups, we have succeeded at establishing a unique innovation platform. I am personally fascinated above all by the agility and versatility of the ARENA2036, which is expressed solely by the fact that I am always discovering new projects on the hall space."

"In the production of the future, data will play a decisive role and the integrated use of development, production, and operational data will become the key factors for trustworthy value creation and utilization systems. For DXC.technology, ARENA2036 is already a special environment. As a leading, independent integration service provider, we can contribute to the networking of these worlds and help shape the data standards of tomorrow. The university environment is of elementary importance for the education of our young talents."
