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.

However, these PLMs face certain challenges in managing the complex and decentralized product lifecycles. 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, this practice results in reducing the overall system efficiency. In this context, this paper assesses and recommends a blockchain-based innovative solution that overcomes the challenges of existing PLMs, hence increasing the overall system efficiency. Furthermore, this work argues, in a logical way, that the recommended blockchain-based platform provides a secure and connected infrastructure for data handling, processing, and storage at different stages of the product lifecycle. Conclusions: This work can be considered among the first to compare the currently implemented PLMs with a novel blockchainbased method.

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.

Its potential lies in optimising existing business models and creating innovative ones based on various technologies, making them fit for the future by reducing greenhouse gas emissions and fulfilling future decarbonization goals. In order to ensure a successful digital transformation towards decarbonization, managers have to assess the capabilities of their organisation and competently oversee their journey by defining a clear path employing digital maturity models. 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. The proposed model has five maturity levels: assess and align, engage and refine, innovate and collaborate, optimize and personalize, and transform and decarbonize.

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.

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 results show that the novel and specifically developed model outperforms both the manual forecasting approach in practice and auto machine learning models in terms of accuracy. 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.

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.

Centrally controlled production systems rely on basic data management, such as storing the bill of materials and required work schedules. Components of customer orders are added to generate the corresponding production orders. However, this type of production control can pose serious problems in case of unforeseen events such as machine failure or changing customer requirements during production. 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. The smart order uses the functionalities of blockchain technology, such as security, transparency, and immutability, to ensure the integrity of production data. The paper concludes by presenting the expected value propositions of smart order-based production control on the production system.

An increasingly popular approach to address these issues is decentralized production, which involves manufacturing products near to the customers to reduce logistics and warehousing expenses, improve lead times, and decrease carbon emissions. However, the decentralized nature of the production network necessitates a secure communication platform for stakeholders to access authentic data in real-time. In this regard, blockchain technology is identified as a promising solution due to its characteristics, which make it suitable for product data management across its lifecycle, especially in a decentralized production network. Therefore, this work proposes a conceptual framework for a blockchainbased product lifecycle management (PLM) system to ensure data provenance, security, authenticity, and trusted traceability in a decentralized production network.

However, existing models often overlook environmental dimensions, focusing primarily on profit-driven growth. To address this gap, a Digital Decarbonization Maturity Model has been developed. This paper aims to evaluate the model's effectiveness and applicability by assessing the current state of digital decarbonization within organizations and identifying opportunities for advancement, drawing on empirical insights from a focus group.}, language = {en} } @misc{AbdulghaniTugraYilmazWinkler, author = {Abdulghani, Tamer and Tugra Yilmaz, Oguzkan and Winkler, Herwig}, title = {The role of information sharing in supply chain collaboration : impacts and emerging opportunities}, series = {Procedia computer science}, volume = {277}, journal = {Procedia computer science}, publisher = {Elsevier BV}, address = {Amsterdam}, issn = {1877-0509}, doi = {10.1016/j.procs.2026.02.224}, pages = {1859 -- 1868}, abstract = {Effective supply chain management is essential for competitive advantage in an increasingly complex global marketplace, and information sharing between partners is becoming a strategic necessity. This paper aims to investigate information sharing practices within the supply chain of the fast-moving consumer goods sector. Specifically, it explores the challenges associated with these practices and their influence on collaboration among partners. Additionally, it analyzes the practical effects of technology and Industry 4.0 on these processes, emphasizing their impact on enhancing or reconfiguring supply chain collaboration. As a methodological approach, semi-structured interviews were conducted with three key supply chain actors: a supplier, a logistics service provider, and a retailer. The Gioia method was employed to analyze the interview data, thereby generating a meaningful data structure. This resulted in a conceptual model demonstrating the relationship between information sharing and collaborative supply chain performance, providing practical insights for enhancing integration.}, language = {en} } @misc{HayatRuesterWinkler, author = {Hayat, Mubashir and R{\"u}ster, Moritz and Winkler, Herwig}, title = {AI-based maintenance order planning and control of trains : status quo and conceptual considerations}, series = {Procedia computer science}, volume = {277}, journal = {Procedia computer science}, publisher = {Elsevier BV}, address = {Amsterdam}, issn = {1877-0509}, doi = {10.1016/j.procs.2026.02.286}, pages = {2495 -- 2504}, abstract = {Maintenance of trains has a major impact on their availability, safety and cost-effectiveness. To date, planning-intensive processes in train maintenance workshops have been carried out with traditional static planning systems. While these systems have provided a foundation for organizing maintenance work, they are unable to generate optimized maintenance programs. As a result, unplanned additional tasks frequently arise during the actual execution of the maintenance operations, thereby disrupting workflows in maintenance workshops and reducing both economic and operational efficiency. It has been demonstrated that such disruptions often lead to increased maintenance costs, longer lead times, and reduced plant efficiency. Therefore, there is a growing need to shift from static to more dynamic, data-driven approaches for maintenance planning and control in the railway sector. Artificial Intelligence (AI) offers significant potential in this regard, as it facilitates the development of predictive capabilities, dynamic scheduling, and intelligent resource allocation. To this aim, this work presents a conceptual framework designed to enhance maintenance order planning and control in train maintenance workshops. The proposed framework serves as a foundational model for utilizing the AI technologies to reduce inefficiencies, improve scheduling, and ultimately support timely and cost-effective maintenance planning and control strategies for trains. The framework remains conceptual at this stage, which is the main limitation of the work; however, as future work, its practical effectiveness will be explored through implementation in trains maintenance workshop and empirical validation.}, language = {en} }
