Interoperabilität

The growing demand for battery cells offers significant potential for the use of digital solutions in their manufacture, which in turn creates opportunities for added value through adaptive and flexible production systems. A key enabler is interoperable data exchange based on formalized data descriptions. Existing ontologies and information models remain too abstract for direct implementation. This paper presents a requirements analysis of data standards in battery cell manufacturing. A procedure for developing domain-specific standards based on OPC UA (Open Platform Communications Unified Architecture) is derived from the results.

The increasing heterogeneity and complexity of industrial plant components from different manufacturers make it difficult to handle technical documentation consistently. In addition, the flexibility required for system changes challenges the long-term usability and legally compliant design of this documentation throughout the entire life cycle of cyber-physical production systems. This article contributes to the discussion on Technical Documentation 4.0 by systematically analyzing existing specifications and approaches and by proposing a concept for a holistic documentation framework.

The decentralized data ecosystem Gaia-X, which is currently under development, supports the future viability of the digital data economy in Europe. But how can relevant use cases be realized in Gaia-X from a service-oriented perspective? To answer this question, this article presents a methodology that describes a structured and interdisciplinary approach to service development in the ongoing Gaia-X 4 ROMS consortium research project [1]. In this project, federated services are realized in five processing steps on the basis of use cases. IT experts, software developers and industry users can leverage the model to efficiently coordinate the joint realization of use cases with Gaia-X and the goal of sovereign data exchange.

Whilst bIoTope should be understood as a highly flexible and dynamic ecosystem capable of seamlessly integrating arbitrary proprietary IoT platforms, it nevertheless builds upon several core components, which provide essential functionality. Those functionalities referenced in this article, are agnostic to other ecosystem-external systems. Inside of the ecosystem, a micro-service-architecture MSA approach is applied. Using O-MI for technical Interoperability and O-DF for syntactic and semantic interoperability are foundation pillars of the ecosystem.

Information technology is one of the key enabling technologies of future manufacturing. In the two basic business processes manufacturing is located at the intersection point. However, for manufacturing and its value adding purpose, information technology has to be considered as a tool. In this paper the author describes an approach to the components of a new information model inside the future factory.

Digital Engineering is becoming more important due to its potentials in cost reduction as well as a unique instrument to control complex products and processes. Nowadays it is used in the industry to cope with more and more individual products accompanied by efficiency requirements on the production processes. The proceeding technical evolution makes it possible to participate in the domain of services from digital engineering. In this article we address challenges for linking process execution and planning. A logistic example illustrates the fusion of real and virtual world.

In many cases, digital engineering is the only realistic answer to important trends in industry. This includes increasingly customized products, decentralized value chains, increasing complexity and functionality of products as well as the need to reduce the time to market. Digital Engineering has already resulted in many technology-driven changes of the product development process. Probably the most important change is the ability to execute some of the iteration loops of development and test completely in the virtual environment. Further improvements can only be achieved by simultaneously combining development and simulation tools from many different domains, such as mechanical engineering, physics simulation, and software engineering. This article identifies current research issues in the field of distributed interoperable testing environments. Moreover, two examples of current applications are given to illustrate what functionalities can already be utilized today.
