Digitalization and Industry 4.0 continue to shape our industrial environment and collaboration. For many enterprises, a key challenge in moving forward in this matter is the integration of their shop-floor systems (hard- and software) with their office-floor systems to harvest the full potential of industry 4.0.
A multitude of different technologies and respective use-cases available on the market leave many companies startled. This paper presents a set of use-cases for IT-OT-Integration to bring transparency into a company’s digital transformation.
Additionally, a technical requirements profile for integrating IT- and OT-Systems based on the use cases is presented. Both, use-cases and their requirements, guide companies in selecting the digitalization measures that fit their current situation and help in identifying technical challenges that need to be addressed in the transformation process.
The digital transformation brings up various new tasks to manage new business application software and integrate them into existing business processes and legacy systems, which are necessary to keep e.g. a production system running. Today, all these tasks are on the one hand not clearly defined and on the other hand, responsibility of these cross-disciplinary tasks is unclear in companies being mostly structured in a function-oriented way. While quality management has developed to a firmly established function of process excellence years ago, IT-application management is still to become an inevitable part of the digital transformation. There are just a few authors trying to define and describe this part, the related tasks, and necessary roles in an organization. In this paper, we show how the business needs of a company can influence the ideal adaptation of the digitization solutions and thus become the success of the digital transformation. We base the paper on a use case in manufacturing companies. We then describe how companies deal with business application systems today. Based on the framework Aachen Digital Architecture Management we describe how a company can holistically improve the management of business application systems.
Low-Level-Code Based Production Model For Improving Material Requirements Planning In ERP Systems
(2021)
Single and small-series production companies face specific challenges, such as variable customer order decoupling points (CODP), decreasing quantities and rising cost pressure. This leads to a increasing production complexity and growing requirements on Production Planning and Control (PPC). Digitalization’s direct links between objects, people, and machines as well as detailed recording of production progresses opens new solutions for PPC. However, volume of data and the required processing times are increasing. Thus, to achieve near-real-time data processing, a decentralization of decision-making systems can be observed. The function Material Requirements Planning (MRP) is PPC’s original need for Enterprise Resource Planning (ERP) systems. Here, PPC’s overall problem (to fulfil primary requirements for products) is divided into subproblems (to fulfil single production orders). Especially companies characterized by an organization in accordance to the workshop principle, high in-house production depth and variable CODP are confronted with high dynamics in their production systems. This ends in significant differences between primary requirements (overall problem) and single production orders (subproblems). Ultimately, these insufficient PPC data result systematically in a non-optimal overall solution despite optimal partial solutions. This publication combines PPC’s fundamentals from existing commonly known models with current implementation concepts of ERP systems. A newly developed Low-Level-Code based Production Model provides explanations for deviations between the overall problem and its subproblems. Furthermore, information flows of PPC can be structured between a periodically actualized vertical and an event driven horizontal information flow. These recognitions lead to an improvement of PPC by ERP systems.
Networked digitalisation as an enabler for smart products and data-based business models presents companies with numerous and diverse challenges on their way through the digital transformation. Various reference architecture models have been developed in recent years to support these companies. A detailed analysis of these and in particular their use by companies quickly showed that currently existing reference models have major weaknesses in their practical suitability. With the Aachen Digital Architecture Management (ADAM), a framework was developed that specifically addresses the weaknesses of existing reference architectures and specifically takes up their strengths. As a holistic model, specially developed for use by companies, ADAM structures the digital transformation of companies in the areas of digital infrastructure and business development starting from customer requirements. Systematically, companies are enabled to drive the design of the digital architecture, taking into account design fields. The description of the design fields offers a detailed insight into the essential tasks on the way to a digitally networked company. The model is not only a structuring aid, but also contains a construction kit with the design fields to configure the procedure in the digital transformation. The procedure differentiates between the development of the digitalisation strategy and the implementation of the digital architecture. Three different case studies also show how ADAM is used in industry, what structuring support it can provide and how the digital transformation can be configured. The breadth and depth of ADAM enable companies to take the path of digital transformation systematically and in a structured manner, without ignoring the value-creating components of digitalisation. This qualifies ADAM as a sustainability-oriented framework, as it places the economic scaling, needs-based adaptation and future-oriented robustness of solution modules in the focus of digital transformation.
The development of renewable energies and smart mobility has profoundly impacted the future of the distribution grid. An increasing bidirectional energy flow stresses the assets of the distribution grid, especially medium voltage switchgear. This calls for improved maintenance strategies to prevent critical failures. Predictive maintenance, a maintenance strategy relying on current condition data of assets, serves as a guideline. Novel sensors covering thermal, mechanical, and partial discharge aspects of switchgear, enable continuous condition monitoring of some of the most critical assets of the distribution grid. Combined with machine learning algorithms, the demands put on the distribution grid by the energy and mobility revolutions can be handled. In this paper, we review the current state-of-the-art of all aspects of condition monitoring for medium voltage switchgear. Furthermore, we present an approach to develop a predictive maintenance system based on novel sensors and machine learning. We show how the existing medium voltage grid infrastructure can adapt these new needs on an economic scale.
Die Schwerpunktstudie untersucht, inwieweit die Potenziale von digitalen Technologien zur Steigerung der Energieeffizienz in der deutschen Wirtschaft bereits ausgeschöpft und die möglichen negativen Effekte schon heute durch gezielte Maßnahmen eingedämmt werden.
Die Teilstudien der vorliegenden Schwerpunktstudie geben aufschlussreiche Einsichten zum aktuellen Stand der Forschung und zum Einsatz digitaler Maßnahmen zur Steigerung der Energieeffizienz der Unternehmen in der Informationswirtschaft und im Verarbeitenden Gewerbe.
Sowohl in der Forschung als auch in der Praxis zeigt sich, dass die Datenverfügbarkeit und -verarbeitung eine zentrale Hürde darstellt, um die Potenziale digitaler Technologien im Energiebereich realisieren zu können. Somit ist die Verbesserung der Erfassung, Integration, Verarbeitung und des Schutzes von Energiedaten ein zentrales Handlungsfeld und elementare Voraussetzung für die erfolgreiche Planung potenzieller Maßnahmen und deren Evaluierung im Laufe der Umsetzung, sowohl für die Politik als auch Unternehmen.
Wie gesetzliche Zielvorgaben zudem Anreize für Unternehmen setzen, neue Lösungsansätze zu finden und künftig vermehrt in energieeffizienzsteigernde Maßnahmen zu investieren, lesen Sie in der Studie.
Die vernetzte Digitalisierung als Befähiger für Intelligente Produkte und datenbasierte Geschäftsmodelle stellt Unternehmen vor zahlreiche und vielfältige Herausforderungen auf dem Weg durch die digitale Transformation. Zur Unterstützung dieser Unternehmen wurden in den vergangenen Jahren diverse Referenzarchitekturmodelle entwickelt. Eine detaillierte Analyse derselben und insbesondere ihrer Nutzung durch Unternehmen zeigte schnell, dass aktuell bestehende Referenzmodelle große Schwächen in der Praxistauglichkeit aufweisen. Mit dem Aachener Digital-Architecture-Management (ADAM) wurde ein Framework entwickelt, das gezielt die Schwächen bestehender Referenzarchitekturen adressiert und ihre Stärken gezielt aufnimmt. Als holistisches Modell, speziell für die Anwendung durch Unternehmen entwickelt, strukturiert ADAM die digitale Transformation von Unternehmen in den Bereichen der digitalen Infrastruktur und der Geschäftsentwicklung ausgehend von den Kundenanforderungen. Systematisch werden Unternehmen dazu befähigt, die Gestaltung der Digitalarchitektur unter Berücksichtigung von Gestaltungsfeldern voranzutreiben. Die Beschreibung der Gestaltungsfelder bietet einen detaillierten Einblick in die wesentlichen Aufgaben auf dem Weg zu einem digital vernetzten Unternehmen. Dabei stellt das Modell nicht nur eine Strukturierungshilfe dar, sondern beinhaltet mit den Gestaltungsfeldern einen Baukasten, um das Vorgehen in der digitalen Transformation zu konfigurieren. Das Vorgehen differenziert zwischen der Entwicklung der Digitalisierungsstrategie und der Umsetzung der Digitalarchitektur. Drei unterschiedliche Case-Studys zeigen zudem auf, wie ADAM in der Industrie konkret genutzt, welche Strukturierungshilfe es leisten und wie die digitale Transformation konfiguriert werden kann. Durch die Breite und Tiefe von ADAM werden Unternehmen befähigt, den Weg der digitalen Transformation systematisch und strukturiert zu bestreiten, ohne die wertschöpfenden Bestandteile der Digitalisierung außer Acht zu lassen. Dies qualifiziert ADAM zu einem nachhaltigkeitsorientierten Framework, da es die wirtschaftliche Skalierung, die bedarfsgerechte Anpassung und die zukunftsgerichtete Robustheit von Lösungsbausteinen in den Fokus der digitalen Transformation rückt.
Die digitale Transformation stellt Unternehmen fortlaufend vor neue Herausforderungen, die richtig eingeschätzt und bewältigt werden müssen. Häufig fehlt ein strukturierter Gesamtansatz, mit dem Sie die digitale Transformation Ihres Unternehmens konzeptionieren und nachhaltig umsetzen können. Wir am FIR an der RWTH Aachen haben in den letzten Jahren zahlreiche Projekte zur Gestaltung der digitalen Transformation in Unternehmen durchgeführt und basierend auf diesen Erfahrungen ein Framework entworfen, um Ihnen genau dieses Wissen weiterzugeben und Ihnen zu helfen, bestehende Herausforderungen anzugehen. Unser Modell 'Aachener Digital-Architecture-Management' (ADAM) dient der Gestaltung von Digitalarchitekturen.
The number of cyber-attacks on small and medium enterprises (SMEs) is constantly increasing. SMEs do not recognize the attacks until the damage has occurred. Only then, they fight with measures to increase IT-security and IT-safety. Many studies come to the point that this refers to a lack of budget, expertise and awareness of the need for IT-security. There are many compendia with recommendations for action, but they are too comprehensive and unspecific to the individual needs of SMEs. In this paper, we present the results of a research activity on the gaps that address the challenges faced by SMEs. In addition, we develop a concept for a serious gaming approach that includes an economic perspective on IT-security measures and shows how SMEs can derive their own IT-seurity target state
Since 2016, the “Digital in NRW” Competence Centre has been supporting SMEs in the manufacturing industry in designing their individual digital transformation. With an Industry 4.0 maturity assessment, we define the status quo of SMEs, derive SME-specific measures from this, develop a digitalization roadmap and accompany the SME transformation. This paper presents the results of the four-year SME support. By analyzing the results of all maturity assessments, potential analysis and design workshops, we present the most frequent and most effective measures for a successful digital transformation of SMEs. The result of the paper is an action guideline for SMEs to initiate their own digital transformation based on formalized experience.
