However, even after more than 10 years of the technology's existence, it is barely used for any self-sustaining applications. This raises the question of why BC cannot prevail against its alternatives. With this paper we want to identify criteria by which the added value of BCT can be measured. Furthermore, we want to evaluate how well the different supply chains (SC) exploit the added values of BCT. Methods: For this, we identified real-world examples and case studies for luxury, food, and healthcare SCs. These examples are described in detail and then analyzed for their added value compared to possible alternatives. Results: The results show that in the clusters of food and healthcare SCs, no general added value of BC over current best-practice solutions could be verified. Luxury SCs manage valuable products that are typically traded in small quantities. It is within this cluster that the implementation of BC can be justified best. Conclusions: In conclusion, this study shows that the application of BCT is especially beneficial for goods with a high value and low trade volume. In addition, the interface between reality and the digital twin should be as secure as the database or BC solution itself. Furthermore, the demand for transparency and immutability of data should be more important than the need to protect sensitive data. Finally, SC participants, especially the end customer, must also be able to appreciate the advantages of BCT.}, language = {en} } @misc{BerneisWinkler, author = {Berneis, Moritz and Winkler, Herwig}, title = {Fallstudie zur Fabrikplanung im Greenfield}, series = {WiSt Wirtschaftswissenschaftliches Studium}, volume = {51}, journal = {WiSt Wirtschaftswissenschaftliches Studium}, number = {1}, issn = {0340-1650}, pages = {58 -- 63}, language = {de} } @misc{KuteyiWinkler, author = {Kuteyi, Damilola and Winkler, Herwig}, title = {Logistics Challenges in Sub-Saharan Africa and Opportunities for Digitalization}, series = {Sustainability}, volume = {14}, journal = {Sustainability}, number = {4}, issn = {2071-1050}, doi = {10.3390/su14042399}, pages = {18}, abstract = {Improvements in logistics performance are considered to be a significant driver of economic growth.

Methods: To this aim, this work investigates the currently implemented PLMs used in industries through the exploration of various software reviews and selection websites. Accordingly, these existing PLMs are quantitatively compared and analyzed. Results: The analysis shows that most of the existing PLMs do not contain all the required features; therefore, industries integrate different software to create a full-fledged PLM system.

However, before any platform is adopted, its nature, functionalities, and adaptability need to be clearly defined, evaluated, and verified. In this context, the proposed work explores the available blockchain-based platforms that can be used for the purpose of product lifecycle management. We then apply one of the multi-criteria decision-making techniques, i.e., the analytic hierarchy process (AHP), to select the best possible blockchain-based platform for PLM. As transaction speed, data privacy, and scalability are our prime concerns in PLM, we only considered the permissioned (private) blockchain platforms as available alternatives in the final selection process. Results achieved on the basis of considered criteria show that Hyperledger Fabric is the top-ranked among available alternatives to be used for PLM. Furthermore, as blockchain is a new technology, a clear comparison of the available platforms based on the performancebased metrics and key performance indicators is not completely matured and is still in the development stage.

For this purpose, the analysis focused on published literature concerning digital maturity models developed to guide organisations in navigating their digital transformation journey. A systematic literature review of 36 selected digital maturity models is presented in this paper. These models overlook decarbonisation measures and focus solely on demonstrating digital capabilities, efficiency and profit growth. Therefore, a maturity model for digital decarbonization encompassing dimensions of decarbonization goals, business model innovation, customers and suppliers, products and services, employees, collaboration, processes and activities, data, and IT-infrastructure, -security and -technology has been developed. It assists organisations in reducing their carbon footprint by strategically and effectively leveraging digital technologies.

On the one hand, they deal with issues related to data transparency, traceability, and security in constant back-and-forth communication exchange between customers and sub-contractors having to confirm the order status. On the other hand, there are significant obstacles when it comes to integrating their traditional order management systems with the partner organization's information systems within the production network. These complexities tend to decrease the ability of OEMs to remain flexible and profitable. Therefore, they are constantly looking for feasible solutions to overcome these issues and improve their order management processes. To this aim, this work proposes a novel blockchain-based conceptual framework for order management that intends to establish a secure environment for efficient communication and data integrity. The decentralized and immutable nature of blockchain makes it capable of providing real-time data as well as ensuring data security and transparency. Furthermore, this work also set up basic level SQLite3 databases and design prototypical on-chain and off-chain smart contract logics that can be used to automate various operations and decisions making in order management, thereby, improving the overall order processing efficiency. According to the authors knowledge, there is no such framework available in research. Therefore, it is suggested that organization can utilize the proposed framework to develop their own blockchain based order management systems.}, language = {en} } @misc{EichenseerWinkler, author = {Eichenseer, Patrick and Winkler, Herwig}, title = {Predicting picking and workforce planning for internal shopfloor material logistics - a simulative, data-driven forecasting model}, series = {Journal of Modelling in Management}, volume = {2024}, journal = {Journal of Modelling in Management}, publisher = {Emerald}, issn = {1746-5664}, doi = {10.1108/jm2-09-2024-0288}, abstract = {Purpose With increasing demands for competitiveness, demand fulfilment and cost efficiency, the need to optimise workforce planning in logistics has become crucial. This applies not only to external customer demands, but also to internal customers, i.e. production. For this reason, the purpose of this paper is to develop a simulative, data-driven model that predicts the internal shopfloor material logistics demands. Design/methodology/approach It is a hybrid approach that includes both deterministic and probabilistic components and is an alternative to advanced but data and knowledge-dependent machine learning algorithms. Inductive, self-developed procedures, heuristic calculation rules and consideration of real-world factors form the basis of the prediction of the number of picks. The number of picks predicted in the first step forms the basis for deriving the number of employees required in the second step, and thus the basis for optimised workforce planning. The developed approach was then validated in a case study in a real company. Findings The results show that the model significantly optimises not only the planning efficiency, but also the forecasting effectiveness through better decision making in demand prediction and workforce planning in internal shopfloor material logistics compared to the status quo on a weekly basis (95.5\% accuracy in the case study). This improved decision making leads to increased efficiency throughout the intralogistics/production system. Originality/value A structured approach is described for systematically predicting the number of internal picks, which is highly relevant in practice and cannot be found in the existing literature (from the data model to the calculation rules, including statistical influencing factors, to the prediction).

The outperformance is particularly strong in the short term. Based on the predicted delivery positions, an optimised workforce planning was subsequently carried out in the case study company.

Die h{\"a}ufigsten Herausforderungen sind demnach die Ressourcenverf{\"u}gbarkeit, lange Lieferzeiten, der Fachkr{\"a}ftemangel und preisgetriebene Themen. Experten wurden zu aktuellen Ereignissen befragt, wie Rohstoffpreisschwankungen, der Zero-Covid-Strategie von China und Knappheiten in der Logistik. Preisschwankungen betrafen die meisten Unternehmen, w{\"a}hrend Krieg und Sanktionen nur indirekt wirkten. Die Zero-Covid-Strategie f{\"u}hrte zu Vertrauensverlust in China und Knappheiten in der Logistik zu h{\"o}heren Transportkosten. Der Fachkr{\"a}ftemangel wurde auch als aktuelles Ereignis genannt. ▪ Der zweite Themenkomplex ist Ver{\"a}nderungen im SCM gewidmet. Dabei wurde insbesondere der Wandel in komplexere Netzwerke, der Aufstieg des E-Commerce und die Bedeutung von Vertrauen und Transparenz angef{\"u}hrt als wesentliche Ver{\"a}nderungen. Supply Chains sind gewachsen und komplexer geworden, aber auch die Qualit{\"a}t der Vernetzung hat sich verbessert. E-Commerce f{\"u}r Standardprodukte wird weiter an Relevanz gewinnen. Kein Trend zur Deglobalisierung wurde festgestellt. Die Experten sind sich einig, dass Supply Chains "too lean" geworden sind und das Risikomanagement wichtiger ist. Das oberste Ziel sollte sein, die Produktion und Lieferf{\"a}higkeit sicherzustellen. ▪ Der dritte Themenkomplex befasst sich mit Nachhaltigkeit, einschließlich des Lieferkettengesetzes (LkSG), Dekarbonisierung und Nachhaltigkeitsnachweisen. Die meisten Unternehmen erf{\"u}llen die Anforderungen des LkSG und nehmen das Gesetz als Klausel in Vertr{\"a}gen auf. B{\"u}rokratie in Deutschland f{\"u}hrt zu hohen Kosten, besonders f{\"u}r kleine Unternehmen. Kosteneinsparungen sind der gr{\"o}ßte Treiber bei der Dekarbonisierung. Nachhaltigkeit wird immer wichtiger und kann {\"u}ber Zertifikate nachgewiesen werden. ▪ Im vierten Themenkomplex Software wurde die Anpassungsf{\"a}higkeit von ERP-Systemen bem{\"a}ngelt und automatische Bestellungen wurden kontrovers betrachtet. Die meisten Experten verzichten aus Sicherheitsgr{\"u}nden auf Cloud-basierte L{\"o}sungen aufgrund des hohen Risikos f{\"u}r Cyberangriffe und m{\"o}glicher Gefahren f{\"u}r die Supply Chain. ▪ In Themenkomplex f{\"u}nf wurden neue Technologien im SCM besprochen. AR wird f{\"u}r die Wartung von Maschinen eingesetzt und VR f{\"u}r Simulation und Planung. IoT wird f{\"u}r predictive Maintenance genutzt, Treiber der Automatisierung ist der Fachkr{\"a}ftemangel. Big Data \& AI sollen die Vorhersage der Nachfrage verbessern. Additive Fertigung hat Potenzial f{\"u}r Automatisierung und sinkende Kosten. Die Blockchain gilt als komplex und kann als geteilte Datenbank, Zahlungssystem und zur Rechnungsteilung dienen. ▪ Im sechsten Themenkomplex Sichtbarkeit halten Experten Transparenz f{\"u}r wichtig, sie ist noch zu gering aber bietet Potenzial zur Erkennung von Risiken.

On the other hand, 5G technology offers in theory opportunities for high-accuracy positioning beyond mobile communication. Local 5G networks in industrial settings could leverage existing infrastructure for positioning. Although previous research demonstrates the theoretical capabilities of 5G positioning, practical trials cannot be performed due to hardware still being in early research developmental stages. This research aims to close the gap between research and industrial use by assessing the technical feasibility of 5G indoor positioning in an automotive production environment. To achieve this, use cases from research and industry are categorized into different scenarios based on distinct requirements. Representative use cases are analyzed considering system requirements and their feasibility. For this, first the overall concept of 5G positioning is tested in a research lab, followed by simulations of 5G positioning in an industrial environment. This is performed to determine the technical capability and expected accuracy. The simulations show that sub-meter accuracies can be achieved when combining 5G positioning with line� of-sight filtering. This study highlights the promising role of 5G as a real-time locating system in industrial settings.

In such scenarios, costly and time-consuming re-scheduling becomes necessary, which endangers the company's competitive position and leads to data retention issues. This paper introduces a new method of production control based on the concept of smart orders. Smart orders use smart contracts for autonomous routing based on programmed information in the source code, enabling self-control through the production system. Smart contracts are transaction programs that work with 'if-then logic", allowing for partially flexible process schedules and reducing the need for human intervention.

This model covers nine dimensions: decarbonization goals, business model innovation, customers and suppliers, products and services, employees, collaboration, processes and activities, data, and IT-infrastructure, -security and -technology, that present a holistic approach to reduce CO2 emissions in organizations. These dimensions are assessed against five maturity levels: beginner, adopter, integrator, innovator, and transformer, indicating various degrees of maturity within each dimension. These levels provide a pathway from beginner to more advanced level with respect to adopting digital technologies for the decarbonization goal.}, language = {en} } @misc{KoenigWinkler, author = {K{\"o}nig, Mathias and Winkler, Herwig}, title = {Montage im Wandel : empirische Ergebnisse der Digitalisierung}, series = {Industry 4.0 Science}, volume = {41.
