Integration of Asset Aministration Shells

Up until now, the primary focus has revolved around processes, development, production, and assembly. Subproject 5 marks the commencement of various cross-sectional topics that are now entering the fray. SP5 to SP10 address the integration of Asset Administration Shells into composite components, automatically running negotiation processes, Data Governance, testing, and knowledge transfer. Additionally, the work in subprojects 5-8 is being bolstered by the expertise of subcontractors.

Objectives of the Subproject

Subproject 5 aims to develop implementation concepts for the integration and interconnection of Asset Administrative Shells. So far, the focus has been more on defining the Asset Administration Shell itself, determining necessary properties and parameters. The aim of SP5 is to find ways of integrating them into complete processes. To achieve this, cross-relationships between individual Asset Administration Shells or between individual data and administration shells need to be described. The integration of Asset Administration Shells will be simulated using a selected composite component as a basis.

Work Focus

SP5 primarily focuses on the integration of Asset Administration Shells and content. It builds upon the groundwork laid by subprojects 1-4 and leverages the outcomes of previous subprojects. Hierarchization of data plays a major role in this subproject. Additionally, it seeks to answer the question: How can a suitable machine or resource be identified that can cut and press, given the context of Asset Administration Shells integration?

Work Status

SP5 commenced in December 2022, and the first requirements analysis workshops have already taken place. Discussions revolved around questions such as: Which data, models, sub-models, and Asset Administrative Shells need to be integrated? How should relationships and hierarchies be mapped?

Furthermore, an approach for the composite component has been modeled, comprising semi-finished products and individual components for the cable harness. The composite component is intended to facilitate the description of necessary capabilities at the resource level, where machines operate. An alignment between the offered and required capabilities must be achieved.

Next Steps

The next steps involve the detailed elaboration of the requirements (WP5.1) and the concrete modeling of an example wiring harness based on Asset Administration Shells (WP5.2). A connection to Catena-X will be prepared in close cooperation with SP 8. Additionally, the tasks for the subcommissions of 4soft and Fraunhofer IESE are being formulated. These points are planned to be clarified in further workshops.

Subcontracting Details:

4soft will be responsible for the integration of VEC models. This task involves mapping hierarchies in the Asset Administration Shell and addressing the nesting capability of Asset Administration Shells. The industry-standard VEC will be utilized for this purpose, and the result should be accessible through the AASX Package Explorer.

Fraunhofer IESE will focus on addressing distributed Asset Administration Shells. This entails exploring how to couple and synchronize distributed Asset Administration Shell infrastructures. The main objective is to establish coupling and synchronizability among different partners along the value chain. Updates must be exchanged securely, reliably, and rapidly. Fraunhofer IESE has already developed a suitable middleware called "BaSyx" and applied it in numerous projects.

Expected Results

Upon completing the requirements analysis, a functional implementation concept with a pilot application that is applicable across multiple value creation stages will be developed. Composite components for the wire harness and production resources will be defined, and a capability-based mapping between production resources and the wire harness will be devised, along with the collection of quality data.
