Supply chains form the backbone of modern economies and therefore require reliable information flows. In practice, however, supply chains face severe technical challenges, especially regarding security and privacy. In this work, we consolidate studies from supply chain management, information systems, and computer science from 2010–2021 in an interdisciplinary meta-survey to make this topic holistically accessible to interdisciplinary research. In particular, we identify a significant potential for computer scientists to remedy technical challenges and improve the robustness of information flows. We subsequently present a concise information flow-focused taxonomy for supply chains before discussing future research directions to provide possible entry points.
Die Vernetzung von Mitarbeiter*innen und Maschinen sowie die zunehmende Automatisierung, auch von Wissensarbeit, wird die Rolle der Beschäftigten im industriellen Wertschöpfungsprozess fundamental verändern. Aus diesem Grund ist arbeitsbezogene Kompetenzentwicklung aus wirtschaftlicher, gesellschaftlicher sowie sozialer Perspektive ein zentraler Schlüsselaspekt für die mittelfristige Sicherung der Wettbewerbsfähigkeit. Personalabteilungen haben bislang jedoch meist nur bedingt Kenntnisse über die bevorstehenden Veränderungen und die sich daraus ergebenden Kompetenzanforderungen an die Mitarbeiter*innen. Ziel des Forschungsvorhabens LidA war es, die sich aufgrund der fortschreitenden Digitalisierung verändernden Kompetenzanforderungen entlang definierter Industrie-4.0-Reifegradmodelle zu spezifizieren. Hierzu wurden Beschäftigte befähigt, indem zum einen ihre Selbstlernkompetenz gefördert wurde und zum anderen individuelle Lernpfade abgeleitet worden sind. Anschließend wurden diese mit passender Didaktik in Lehr- und Lernmodule überführt und auf einer bewährten Open-Source-Plattform für eine breite Nutzergruppe verfügbar gemacht. Diese soll einem breiten Nutzerkreis, speziell KMU, eine bedarfsgerechte Schulung der Mitarbeiter*innen im Zeitalter des digitalen Wandels gewährleisten.
The manufacturing industry consumes 54% of global energy and attributes for 20% of global CO2 emissions, demonstrating the industry’s role as global driver of climate change. Therefore, reducing its carbon footprint has become a major challenge as its current energy and resource consumption are not sustainable. Industrie 4.0 presents a chance to transform the prevailing paradigms of industrial value creation and advance sustainable developments. By using information and communication technologies for the intelligent networking of machines and processes, it has the potential to reduce energy and material consumption and is considered a key contributor to sustainable manufacturing as proclaimed by the European Commission in the term “twin transition”. As organizations still struggle to utilize the potential of Industrie 4.0 for a sustainable transformation, this paper presents a framework to successfully align their own twin transition. The framework is built upon three key design principles (micro level: leverage eco-efficient operations, meso level: facilitate circularity and macro level: foster value co-creation) derived using case study research by Eisenhardt, and four structural dimensions (resources, information systems, organizational structure and culture) based on the acatech Industrie 4.0 Maturity Index. Eleven interconnected areas of action are defined within the framework and offer a holistic and practical approach on how to leverage an organization’s twin transition. Within the conducted research, the framework was applied to the challenge of information quality and transparency required for high-value secondary plastics in the manufacturing industry. The result is a digital platform design that enables information transactions for secondary plastics and establishes a circular ecosystem. This shows the applicability of the framework and its potential to facilitate a structured approach for designing twin transitions in the manufacturing industry.
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.
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.
Ongoing digitalization and Industry 4.0 enable the development of new business models due to the increase in available data and digital connected products. A promising business model type for the machinery and plant engineering industry are subscription models, consisting of products and services offered in return for continuous payments. However, subscription-based business models are associated with extensive changes in the traditional machinery and plant engineering industry, in particular, for small and medium-sized companies (SMEs). Established concepts for the development of value propositions and business models neglect important aspects, such as the integrated development and optimization of products and services across the entire life cycle or the data infrastructure. This paper presents a concept for a methodology to support SMEs developing value propositions within subscription models. Therefore, the systematic identification of customer benefits, the determination and prioritization of subscription relevant functionalities as well as the design of product and service elements addressing those functionalities are the main aspects on which the focus is placed on. The result is a subscription value proposition canvas for SMEs to address the impact of subscription models on products and services.
Understanding the Organizational Impact of Robotic Process Automation: A Socio-Technical Perspective
(2022)
Interest in AI-driven automation software is growing constantly across
all industries, as these technologies enable companies to almost automate administrative processes completely and significantly increase operational efficiency.
However, many implementation attempts fail due to a lack of understanding of how these technologies affect the various socio-technical aspects that are intertwined in an organisation. This leads to a widening gap between value propositions of automation software and the ability of companies to exploit them. For long-term
success, collaboration between humans and software robots in the organization must be optimised. Therefore, the social, technical, and organizational impact of Robotic Process Automation was investigated. Following a socio-technical systems approach, a model was developed and validated in a use case of a company in the mechanical engineering sector. Knowing the influencing factors before launching large-scale automation initiatives will help practitioners to better exploit
efficiency potentials and increase the long-term success.
Künstliche Intelligenz (KI) hat als Technologie in den vergangenen Jahren Marktreife erlangt. Es existiert eine Vielzahl benutzerfreundlicher Produkte und Services, welche die Anwendung von KI im Alltag und im Unternehmen vereinfachen. Die Herausforderung, vor denen Anwendende, gerade im betriebswirtschaftlichen Kontext, stehen, ist nicht die technische Machbarkeit einer KI-Applikation, sondern deren organisatorisch und rechtlich zulässige Gestaltung. Zu einer zunehmenden Dynamik in der Gesetzgebung kommt ein gesellschaftliches Interesse an der Kontrolle und Transparenz über die für KI-Modelle erhobenen Daten. Die Diskussion über Datensouveränität im geschäftlichen und privaten Alltag rückt mehr und mehr in das Zentrum der öffentlichen Aufmerksamkeit.
Datenbasierte KI-Anwendungen stehen damit in einem Spannungsfeld zwischen den Potenzialen, die das Erheben und Teilen von Daten über Unternehmensgrenzen hinweg bietet, und der Herausforderung, die Datensouveränität der involvierten Personen zu wahren. Die vorliegende Studie soll erstens über die Auswirkungen der Datensouveränität und die damit verbundenen aktuellen und kommenden Regularien auf KI-Anwendungsfälle aufklären. Dafür wurden Expertinnen und Experten aus den Bereichen Recht, KI- und Organisationsforschung befragt. Zweitens zeigt die Studie Potenziale und Best Practices von KI-Anwendungsfällen mit überbetrieblichem Datenaustausch auf. Dafür wurden Fallstudien in Unternehmen durchgeführt, die bereits erfolgreich Datenaustausch in ihre Geschäftsmodelle integriert haben, um ihre KI-Applikationen zu betreiben und zu verbessern.
Driven by different trends, such as digitalization, the number of companies aiming for successful business transformation is increasing, while new structures and systems are paving the way. Strategic agile management systems offer significant potential benefits given the increasing speed of the evolving environment in which organizations find themselves these days. To select and implement the appropriate strategic agile management system, companies need to understand the underlying theoretical principles to be able to select the most suitable for the respective company and to introduce it based on individual adaption. Within this paper, a morphology is presented to improve theoretical knowledge about strategic agile management systems. Creating a common understanding of strategic agile management systems and their current areas of application creates a suitable frame of reference for future research projects.
Augmented reality seems to offer great potential benefits in the field of industrial services. However, the question of the exact benefits, both monetary and qualitative, is difficult to evaluate, as is the case with IT investments in gen-eral. Within the framework of the DM4AR research project, an evaluation model was therefore developed. Based on group discussions and interviews on potential AR use cases, a list of monetary and qualitative benefits was compiled to form the basis for selecting suitable evaluation modules in the existing literature. These include an impact chain analysis in the form of a strategy map, a monetary eval-uation as a calculation of the return on investment, based on the assumptions of the use case as well as existing studies, and a qualitative evaluation in the form of a utility analysis. The outcome is an evaluation model in the form of a multi-perspective approach that considers the impact of AR in the four perspectives of the balanced scorecard (financial, customer, internal business processes, learning and growth). The results of the qualitative and monetary evaluation can be sum-marized in a 2D matrix to support decision-making.
