Factory automation and production are currently
undergoing massive changes, and 5G is considered being a key
enabler. In this paper, we state uses cases for using 5G in the
factory of the future, which are motivated by actual needs of the
industry partners of the “5Gang” consortium. Based on these use
cases and the ones by 3GPP, a 5G system architecture for the
factory of the future is proposed. It is set in relation to existing
architectural frameworks.
In diesem Paper wird eine Architektur für Kommunikationsnetze für industrielle Anwendungen vorgestellt, die neue 5G-Technologien mit vorhandener Kommunikationstechnik auf der Feldbusebene kombiniert. Diese Architektur verbindet private und öffentliche Mobilfunknetze mit lokalen Funktechnologien, um einen flexiblen Aufbau zu ermöglichen, der in der Lage ist, viele industrielle Anwendungsfälle zu unterstützen. Es wird gezeigt, wie die Errungenschaften, die mit der neuen 5G-Technologie eingeführt werden, einen großen Bereich der industriellen Anforderungen erfüllen können. Weiterhin werden relevante Anwendungsfälle beschrieben und eine Gesamtsystemarchitektur vorgeschlagen, welche nicht nur die technischen, sondern auch die funktionalen Anforderungen, welche von den spezifischen Anwendungen heutiger und zukünftiger Herstellungsprozesse gestellt werden, erfüllen kann.
The digitalization of manufacturing processes is expected to lead to a growing interconnection of production sites, as well as machines, tools and work pieces. In the course of this development, new use-cases arise which have challenging requirements from a communication technology point of view. In this paper we propose a communication network architecture for Industry 4.0 applications, which combines new 5G and non-cellular wireless network technologies with existing (wired) fieldbus technologies on the shop floor. This architecture includes the possibility to use private and public mobile networks together with local networking technologies to achieve a flexible setup that addresses many different industrial use cases. It is embedded into the Industrial Internet Reference Architecture and the RAMI4.0 reference architecture. The paper shows how the advancements introduced around the new 5G mobile technology can fulfill a wide range of industry requirements and thus enable new Industry 4.0 applications. Since 5G standardization is still ongoing, the proposed architecture is in a first step mainly focusing on new advanced features in the core network, but will be developed further later.
This research area focuses on the management systems and principles of a production system. It aims at controlling the complex interplay of heterogeneous processes in a highly dynamic environment, with special focus on individualized products in high-wage countries. The project addresses the comprehensive application of self-optimizing principles on all levels of the value chain. This implies the integration of self-optimizing control loops on cell level, with those addressing the production planning and control as well as supply chain and quality management aspects. A specific focus is on the consideration of human decisions during the production process. To establish socio-technical control loops, it is necessary to understand how human decisions are made in diffuse working processes as well as how cognitive and affective abilities form the human factor within production processes.
