Das Gegenteil von Theorie ist die Praxis. So sagt man landläufig und unterstellt damit oft, dass wissenschaftliche Erkenntnisse nicht immer für den Alltag taugen. Dass Theorie aber nicht gleich Theorie ist und Wissenschaft und Praxis trotz aller Unterschiedlichkeit aufeinander angewiesen sind, darauf weist das FIR an der RWTH Aachen schon mit der Auflösung seines Akronyms hin: „Forschung. Innovation. Realisierung.“ Hier zielen alle Forschungsaktivitäten darauf ab, Lösungen für reale Herausforderungen aus der Praxis zu schaffen, die am Ende auch umsetzbar sind. Eine nutzenbringende Verbindung zwischen den beiden scheinbar so unterschiedlichen Welten ist dafür unabdingbar und diese Lücke schließt das FIR mit Industriekooperationen, Wissens und Technologietransfer sowie Weiterbildungsangeboten auf vielen Ebenen. Nicht zuletzt positionierte sich das FIR als leitendes Institut des Clusters Smart Logistik auf dem RWTH Aachen Campus und füllt diese Rolle seit über 10 Jahren erfolgreich aus.
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.
Die Instandhaltung, konsequent zu Ende gedacht, ist ein zentraler Treiber für den Unternehmenswert und wird damit für viele produzierende Unternehmen zum strategischen Erfolgsfaktor. Da für die meisten Unternehmen ein umfangreicher Mitarbeiter- und Ressourcenaufbau nicht in Frage kommt, stehen diese Unternehmen vor der Herausforderung, den Wertbeitrag vorhandener Mitarbeiter und Ressourcen zu maximieren. Dies führt zum Konzept Return on Maintenance (RoM). Der Wertbeitrag der Instandhaltung geht dabei über die reine Herstellung von Verfügbarkeit zu möglichst geringen Kosten weit hinaus. Zielgrößen wie Ausschussrate, Energieeffizienz, Materialeffizienz aber auch die Minimierung von Rüstzeiten zeigen die vielfältigen Zielgrößen der Instandhaltung auf.
Technology management can significantly influence the strategic decisions of a company and thus cause success or failure. Basic templates for technology management are technology radars as well as the determination of the technology readiness level (TRL) to be able to evaluate the maturity of newly deployed technologies (e.g., newcomer vs. established). The radars, as well as the TRL, are identified in time-consuming, manual research by subject matter experts from external consultancies. This process is often repeated due to the further development and new development of technologies so that the necessary research becomes an ongoing task. The TechRad research project, therefore, aims to automate the identification of the TRL as well as technology radars using web crawling and Natural Language Processing (NLP). To commercialize the pre-competitive prototype, the development of a pre-competitive business model is the goal of this paper. Based on customer analyses, a target group definition is created. Based on user interviews, the precompetitive business model will be detailed in a four-step approach using a business model canvas and a value proposition canvas.
The operation of CNC milling is expensive because of the cost-intensive use of cutting tools. The wear and tear of CNC tools influence the tool lifetime. Today’s machines are not capable of accurately estimating the tool abrasion during the machining process. Therefore, manufacturers rely on reactive maintenance, a tool
change after breakage, or a preventive maintenance approach, a tool change according to predefined tool specifications. In either case, maintenance costs are high due to a loss of machine utilization or premature tool change. To find the optimal point of tool change, it is necessary to monitor CNC process parameters during machining and use advanced data analytics to predict the tool abrasion. However, data science expertise is limited in small-medium sized manufacturing companies. The long operating life of machines often does not justify investments in new machines before the end of operating life. The publication describes a cost-efficient approach to upgrade legacy CNC machines with a Tool Wear Prediction Upgrade Kit. A practical solution is presented with a holistic hardware/software setup, including edge device, and multiple sensors. The prediction of tool wear is based on machine learning. The user interface visualizes the machine condition for the maintenance personnel in the shop floor. The approach is conceptualized and discussed based on industry requirements. Future work is outlined.
Eine Herausforderung für produzierende Unternehmen in der Entwicklung intelligenter Produkte besteht darin, dass die Zielstellung, die mit einem intelligenten Produkt verfolgt wird, nicht expliziert ist. Zudem ist oftmals nicht spezifiziert, in welchem Anwendungsfall ein intelligentes Produkt agieren soll. Produzierende Unternehmen benötigen Unterstützung, um eine zielorientierte und folglich wirtschaftliche Melioration existierender Produkte zu gewährleisten. Ebendiese Melioration wird im Kontext von intelligenten Produkten als Smartifizierung bezeichnet und stellt damit einen Entwicklungsprozess dar, der ein bestehendes Produkt als Ausgangssituation im Sinne einer Anpassungskonstruktion expliziert. Die originäre Produktfunktion wird folglich nicht verändert, sondern das Produkt um digitale Funktionen und Dienstleistungen erweitert. Der Artikel befasst sich daher erstens mit der Beschreibung generischer Ziele für den Einsatz intelligenter Produkte im Maschinenbau. Eine Zusammenstellung und Erläuterung solcher Ziele unterstützt Unternehmen, eine Präzisierung der Zielfestlegung in der Initiierungsphase eines Smartifizierungsprojekts durchzuführen. Zweitens wird unter Anwendung der Ziel-Mittel-Beziehung ein Anwendungsfall intelligenter Produkte beschrieben. Abschließend werden beide Aspekte in einer Methode zusammengefasst, wie mittels Ziel- und Anwendungsfallbetrachtung Anforderungen abgeleitet und wie diese Elemente in Vorgehensmodelle der Produktentwicklung eingebettet werden können. Exemplarisch wird anhand einer Stanzmaschine aufgezeigt wie die Methode und die sich daraus ableitenden Ergebnisse im Smartifizierungsprozess zur Entwicklung einer intelligenten Stanzmaschine eingesetzt werden.

Wie kaum ein anderes Phänomen beeinflussen Communities über Plattformen wie Facebook, Wikipedia oder Google unseren privaten und geschäftlichen Alltag durch die Vernetzung und Bereitstellung von Wissen und Informationen. Während noch vor einigen Jahren Online-Foren, als frühe Vorläufer von heutigen Communities, nur für einen sehr kleinen Teil der Gesellschaft zugänglich oder von Interesse waren, sind webbasierte Communities heute für viele Menschen in ihre täglichen Abläufe integriert und scheinbar unersetzlich geworden.
Data-driven transparency in end-to-end operations in real-time is seen as a key benefit of the fourth industrial revolution. In the context of a factory, it enables fast and precise diagnoses and corrections of deviations and, thus, contributes to the idea of an agile enterprise. Since a factory is a complex socio-technical system, multiple technical, organizational and cultural capabilities need
to be established and aligned. In recent studies, the underlying broad accessibility of data and corresponding analytics tools are called “data democratization”. In this study, we examine the status quo of the relevant capabilities for data democratization in the manufacturing industry.
(1) and outline the way forward.
(2) The insights are based on 259 studies on the digital maturity of factories from multiple industries and regions of the world using the acatech Industrie 4.0 Maturity Index as a framework. For this work, a subset of the data was selected.
(3) As a result, the examined factories show a lack of capabilities across all dimensions of the framework (IT systems, resources, organizational structure, culture).
(4) Thus, we conclude that the outlined implementation approach needs to comprise the technical backbone for a data pipeline as well as capability building and an organizational transformation.
Task-Specific Decision Support Systems in Multi-Level Production Systems based on the digital shadow
(2019)
Due to the increasing spread of Information and Communication Technologies (ICT) suitable for shop floors, the production environment can more easily be digitally connected to the various decision making levels of a production system. This connectivity as well as an increasing availability of high-resolution feedback data, can be used for decision support for all levels of the company and supply chain. To enable data driven decision support, different data sources were structured and linked. The data was combined in task-specific digital shadows, selecting clustering and aggregation rules to gain information. Visual interfaces for task-specific decision support systems (DSS) were developed and evaluated positively by domain experts. The complexity of decision making on different levels was successfully reduced as an effect of the processed amounts of data. These interfaces support decision making, but can additionally be improved if DSS are extended with smart agents as proposed in the Internet of Production.
The environment in which companies operate is increasingly volatile and complex. This results in an increased exposure to disruptions. Past disruptions have especially affected procurement. Thus, companies need to prepare for disruptions. The preparedness for disruptions in the context of procurement is significantly influenced by the design of the procurement strategy. However, a high number of purchased articles and a variety of influencing factors lead to high complexity in procurement. The systematic design of the procurement strategy should therefore take into account the criticality of the purchased articles. This enables to focus on the purchased articles that have a high impact on the disruption preparedness. Existing approaches regarding the design of the procurement strategy in uncertain environments either lack practical applicability and objective evaluation or focus on the criticality of raw materials rather than of purchased articles. Therefore, a data-based approach for the systematic design of the procurement strategy in the context of the Internet of Production has been proposed. One central aspect of this approach is the identification of success-critical purchased articles. Thus, this paper proposes a framework for characterizing purchased articles regarding supply risks by combining two systematic analyses. First, a systematic literature review is performed to answer the question of what factors can be used to describe the supply risks of purchased articles. The results are analyzed regarding sources and impacts of risks and thus contribute to a structured characterization of supply risks. Second, existing criticality assessment approaches for raw materials are analyzed to identify categories and indicators that describe purchased articles. The results of both reviews provide the basis for linking product characteristics with supply risks and assessing product criticality which will be integrated into an app prototype.
Companies operate in an increasingly volatile environment where different developments like shorter product lifecycles, the demand for customized products and globalization increase the complexity and interconnectivity in supply chains. Current events like Brexit, the COVID-19 pandemic or the blockade of the Suez canal have caused major disruptions in supply chains. This demonstrates that many companies are insufficiently prepared for disruptions. As disruptions in supply chains are expected to occur even more frequently in the future, the need for sufficient preparation increases. Increasing resilience provides one way of dealing with disruptions. Resilience can be understood as the ability of a system to cope with disruptions and to ensure the competitiveness of a company. In particular, it enables the preparation for unexpected disruptions. The level of resilience is thereby significantly influenced by actions initiated prior to a disruption. Although companies recognize the need to increase their resilience, it is not systematically implemented. One major challenge is the multidimensionality and complexity of the resilience construct. To systematically design resilience an understanding of the components of resilience is required. However, a common understanding of constituent parts of resilience is currently lacking. This paper, therefore, proposes a general framework for structuring resilience by decomposing the multidimensional concept into its individual components. The framework contributes to an understanding of the interrelationships between the individual components and identifies resilience principles as target directions for the design of resilience. It thus sets the basis for a qualitative assessment of resilience and enables the analysis of resilience-building measures in terms of their impact on resilience. Moreover, an approach for applying the framework to different contexts is presented and then used to detail the framework for the context of procurement.
In the food industry, a very large potential of data ecosystems is seen, in which data is understood, exchanged and monetized as an economic asset. However, despite the enormous economic potential, companies in the food industry continue to rely on traditional, product-oriented business models. Existing data in the value chain of industrial food production, e.g., in harvesting, logistics, and production processes, is primarily used for internal optimization and is not monetized in the form of data products. Especially the pricing of data products is a key challenge for data-based business models due to their special characteristics compared to conventional, analog offerings and multiple design options. The goal of this work is therefore to solve this issue by developing a framework that allows the identification of pricing models for data products in the industrial food production. For this purpose, following the procedure of typology formation, essential design parameters and the respective characteristics are derived. Furthermore, three types for pricing models of data products are shown. The results will serve not only stakeholders in the food industry but also manufacturing companies in general as input for an orientation of their databased business models.
Due to shorter product life cycles and the increasing internationalization of competition, companies are confronted with increasing complexity in supply chain management. Event-based systems are used to reduce this complexity and to support employees' decisions. Such event-based systems include tracking & tracing systems on the one hand and supply chain event management on the other. Tracking & tracing systems only have the functions of monitoring and reporting deviations, whereas supply chain event management systems also function as simulation, control, and measurement. The central element connecting these systems is the event. It forms the information basis for mapping and matching the process sequences in the event-based systems. The events received from the supply chain partner form the basis for all downstream steps and must, therefore, contain the correct data. Since the data quality is insufficient in numerous use cases and incorrect data in supply chain event management is not considered in the literature, this paper deals with the description and typification of incorrect event data. Based on a systematic literature review, typical sources of errors in the acquisition and transmission of event data are discussed. The results are then applied to event data so that a typification of incorrect event types is possible. The results help to significantly improve event-based systems for use in practice by preventing incorrect reactions through the detection of incorrect event data.
Die beschriebenen unterschiedlichen Ausprägungen der sechs Gestaltungsfelder im Rahmen der Smart-Maintenance-Roadmap stellen Meilensteine dar, die Unternehmen bei der eigenen Transformationen ihrer Instandhaltungsorganisation unterstützen. Smart Maintenance sollte jedoch nicht als eine endgültige Entwicklungsstufe betrachtet werden. Vielmehr beschreibt Smart Maintenance das Verständnis um den dazugehörigen Transformationsprozess selbst: erfolgreiche Smart-Maintenance-Unternehmen kennen also die Zusammenhänge, die zwischen den jeweiligen Entwicklungsphasen bestehen und können diese für die Umsetzung der folgenden Transformationsschritte ihrer Instandhaltung aber auch angrenzender Organisationseinheiten nutzen. Dabei hilft eine zyklische Betrachtung der nachfolgenden vier Schritte, um den Weg zur Smart Maintenance aktiv und zielgerichtet zu gestalten:
1. Entwicklung eines gemeinsamen Zielverständnisses
2. Regelmäßige Bestimmung der eigenen Position im Smart-Maintenance-Transformationsprozess
3. Ableitung und Sortierung der Entwicklungsschritte in einer individuellen Roadmap
4. Umsetzung der nächsten Entwicklungsschritte auf Basis der zuvor erledigten "Hausaufgaben"
Industry 4.0 and Smart Maintenance represent a great opportunity to make manufacturing and maintenance more effective, safer, and reliable. However, they also represent massive change and corresponding challenges for industrial companies, as many different options and starting points have to be weighed and the individual right paths for achieving Smart Maintenance need to be identified. In our paper, we describe our approach to evaluating maintenance organizations in a case study for the oil and gas industry, developing a shared vision for the future, and deriving economical and effective measures. We will demonstrate our approach, by showcasing a specific example from the oil and gas industry, where a need for action on HSE-relevant critical flanges in the company's piping systems was identified. We describe the steps, that were taken to identify the need for action, the specifications of the project and the criticality analysis of the piping system. This resulted in the derivation of a digitalization measure for critical flanges, which was first commercially analyzed and then the flanges were equipped with a continuous monitoring solution. Finally, a conclusion is drawn on the performed procedure and the achieved improvements.
In Germany’s transition to a more sustainable industrial landscape, electricity generated by wind turbines (WT) remains a mainstay of the energy mix. Operating and maintenance costs, which account for roughly 25% of electricity generation costs in onshore WTs make improvements of maintenance activities a key lever in the economic operation of WTs. Prescriptive maintenance is a possible approach for improved maintenance activities. It is a concept where asset condition data is used to recommend specific actions and has great potential for the operation of wind parks. However, especially small, but also large wind park operators, and maintenance service providers often struggle with the implementation of such a new maintenance approach. As a part of the research project ReStroK, a learning game has been developed to support the training and familiarization of maintenance technicians with the concepts and underlying principles of this maintenance approach. In this paper, the concept for the development of a learning game will be presented. Multiple scenarios for its usage and their corresponding requirements will be discussed and an overview over the game will be given.
Smart-Service-Engineering
(2019)
Die Industrie 4.0 hält viele Möglichkeiten für produzierende Unternehmen bereit, während sie zeitgleich eine Menge Herausforderungen kreiert. In diesem digitalisierten
und globalisierten Marktplatz kommen viele Unternehmen unter Druck, serviceorientierter zu werden und innovative Dienstleistungen wie Smart Services anzubieten. Die digitalen Services schaffen ihren Wert durch die Erweiterung von physischen Produkten. Jedoch haben sich die klassischen Methoden des Service-Engineerings (SE) nicht in ausreichendem Tempo an die digitalisierten Komponenten und veränderten Voraussetzungen angepasst. Hier wird das Smart-Service-Engineering (SSE) als neuer Ansatz für industrielle Smart Services vorgestellt. Smart-Service-Engineering basiert auf einem iterativen Entwicklungsmodell, das agile und kundenorientierte Methoden zur Verringerung der Entwicklungszeit implementiert, um einen frühen Markterfolg zu erreichen. Dabei liegt der Fokus auf den Service-Entwicklungsstufen und der Interaktion dieser Elemente des Smart Service. Schlussendlich illustriert der Beitrag die erfolgreiche Umsetzung des Smart-Service-Engineering-Ansatzes auf ein deutsches mittelständisches Unternehmen der Textilindustrie.
KVD-Service-Studie 2020
(2019)
Im Rahmen der Digitalisierung haben viele Serviceanbieter das Leistungsportfolio um innovative Services und Smart Services ergänzt. Für die Anbieter stellen gerade die Markt- einführung und der Vertrieb dieser Leistungen zwei der zentralen Herausforderungen bei der Etablierung dieser Leistungen dar. Neben bestehenden vertrieblichen Herausforderungen beim Servicevertrieb, wie der Aufklärung und Überzeugung von Kunden und der individuellen Anpassung und Erbringung der Leistung für den Kunden, erfordert der Vertrieb von Smart Services zusätzlich die interdisziplinäre Zusammenarbeit von mehreren Bereichen, den Zugang und die Verarbeitung von Daten sowie die permanente Betreuung der Leistung beim Kunden über den Lebenszyklus. Damit Serviceunternehmen auf dem Markt wettbewerbsfähig bleiben, müssen sich Vertriebsorganisationen erfolgreich weiterentwickeln bzw. völlig neu aufstellen. Für die dargestellten Herausforderungen gilt es, Erfolgsfaktoren für den Vertrieb von Services und Smart Services abzuleiten. Der diesjährige Schwerpunkt der Service-Studie 2020, die vom KVD zusammen mit dem FIR durchgeführt wurde, liegt daher auf dem Themenkomplex `Vertrieb von Services und Smart Services`.
Subscription business transforms traditional business models of machinery and plant engineering. Many manufacturing companies struggle to pull out the potential created by Industry 4.0 and make it economically usable. In addition to technological innovations, it is necessary to transform the business model. This leads to a shift from ownership-based and product-centric business models to outcome-based business models, which focus on the customer's value and thus realize a unique value proposition and competitive advantage – the outcome economy. Based on a case study analysis among manufacturing companies, this paper provides further clarification including a definition and constituent characteristics of subscription business models in machinery and plant engineering.
