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.
People with tremor find it often very difficult to use IT services and therefore attain very low levels of effectiveness, efficiency and satisfaction, when doing so. The currently available user interfaces do not guarantee sufficient precision for information input. Individuals suffering from intention tremor show a significant worsening when moving towards a button, precisely because target-oriented movements produce shaking in the affected body parts. For this target group a new method regarding the information input has been developed and evaluated. This technique enables the persons concerned to input information on a touch screen by using a wiping movement. Variations caused by the tremor are compensated with a continuous movement rather than a single direct movement towards a target field. Moreover, the screen surface causes a significant friction that helps to damp tremor forces. The user input can be identified by the computer with high accuracy by means of special heuristics which also assist barrier free access among the target group.
The shift towards a decentralized electricity supply based on renewable energy sources requires constant communication between the entities in the electric grid. To satisfy this communication need, energy market players have to select suitable communication technologies for their use cases. Conventionally, these decisions are made on a case-by-case, non-systematic basis. This paper proposes a technology configurator, which is a systematic, solution neutral approach for energy market players to select the most suitable communication technology for their communication use case. The developed methodology consists of eight steps, in an interaction between a user and a system, leading to a prioritized list of technology recommendations for the given use case. In conclusion, the proposed approach presents energy market players with a systematic way to select the best suitable communication technology to connect their system to the smart grid.

Digital shadow enables fast adaption of products and production.
Digital, agile businesses outperform traditional businesses because of lower latencies in the entire reaction chain. The capability of using data and generate knowledge will different digital champions from losers.
The goal of Industrie 4.0 is a learning agile company;a mere technology driven approach is not sufficient.
A successful implementation of Industrie 4.0 in manufacturing companies requires a holistic transformation approach.
There are many reasons why the shift towards a learning, agile company fails.
For a successful implementation, the entire company structure has to be considered. A stepwise approach is required to build the agile enterprise - smart use of data is the critical success factor.
Company development within the structuring forcesis based on an Industrie 4.0 development path.
The four structuring forces illustrate the fundamental Industrie 4.0 development and are captured by key questions.
The Maturity Index is developed by renowned partners from industry and research Overview on strategic goals and derived projects.
It is crucial today that economies harness renewable energies and integrate them into the existing grid. Conventionally, energy has been generated based on forecasts of peak and low demands. Renewable energy can neither be produced on demand nor stored efficiently. Thus, the aim of this paper is to evaluate Deep Learning-based forecasts of energy consumption to align energy consumption with renewable energy production. Using a dataset from a use-case related to landfill leachate management, multiple prediction models were used to forecast energy demand.The results were validated based on the same dataset from the recycling industry. Shallow models showed the lowest Mean Absolute Percentage Error (MAPE), significantly outperforming a persistence baseline for both, long-term (30 days), mid-term (7 days) and short-term (1 day) forecasts. A potential decrease of up to 23% in peak energy demand was found that could lead to a reduction of 3,091 kg in CO2-emissions per year. Our approach requires low finanacial investments for energy-management hardware, making it suitable for usage in Small and Medium sized Enterprises (SMEs).
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.
Smartification and digital refinement of products to enable the design of smart ones is a pivotal challenge in the manufacturing industry. Companies fail to design smart products due to missing knowledge of digital technologies and their integral part in product development processes. This paper presents a methodology that enables the derivation of digital functions for smart products through selected cases in manufacturing usage. We develop a morphology that consists of digital functions for smartification. In this context, we explained and derived characteristics by a set of examples regarding smart products in the manufacturing industry. Our methodology reduces the time spent initiating a development project with the focus on smartification.
This paper addresses the challenge of modelling individual cyber-physical systems (CPS) for small and medium-sized enterprises (SMEs) in manufacturing industries. CPS are key technology building blocks for the implementation of Industrie 4.0. Especially for SMEs the increase of production efficiency and reduction of manufacturing costs through CPS offer potential to maintain their competitiveness and innovation capacity. Although SMEs perceive the potential of CPS, they often lack financial and human resources to acquire the necessary CPS-competencies as well as an overview of all the currently available technological solutions. To overcome this issue a matching platform will offer SMEs support in finding suitable CPS-components by letting them express their functional and technical requirements. The matching logic is based on a set of morphologies that encompasses the functional and requirement spectrum of CPS-components. The matching algorithm analyses the input for congruence of requirements and available technologies and suggests suitable technology combinations. This paper describes the methodology of the matching platform, and introduces the research work to define and to develop the technology morphologies. The presented results facilitate the selection and configuration of CPS for SMEs.
Numerous traditional, agile and hybrid development approaches have been proposed for the development of CPS. As the choice of development process is crucial to the success of development projects, it has become a major challenge to identify the best-suited process. This paper introduces a methodology for identifying the best-suited CPS development process, based on the individual boundary conditions for a certain development project within a company. The authors used a set of eight indicators to assess a CPS-development project. The results of the assessment were matched with CPS-development approaches. Based on the matching results a best-suited development process was selected. The application is shown for a use case in the German manufacturing industry. The developed method aims to reduce the risk of project failure due to the wrong choice of development process.
