In diesem Beitrag wird ein neuartiges Konzept für ein hybrides Produktionssystem vorgestellt, das sowohl neue als auch aufbereitete Produkte verarbeiten kann. Im Kern zeichnet es sich durch einen multifunktionalen De- und Remontagearbeitsplatz aus, der mehrere Strategien der Kreislaufwirtschaft in das Wertschöpfungssystem integriert. Damit wird das Ziel verfolgt, die industrielle Transformation hin zu einer kreislauffähigen Produktion zu fördern und effizient zu gestalten.
Development of a platform business model for co-creation ecosystems for sustainable furniture
(2023)
Existing design platforms with multi-dimensional value chains currently have deficits in terms of their business models, resulting in insufficient attention to sustainability goals and individual requirements for products of these platforms. Co-creation approaches, such as the Do-It-Together (DIT) approach for furniture, involve customers and manufacturers as equal partners in the design and production process. This allows customers to have more influence on the sustainability and individualization of products. The existing literature addresses sustainability-oriented design principles for platform business models, but concrete platform business models for multidimensional DIT cocreation of furniture are still missing. Therefore, the objective of this paper is to develop a business model for a DIT co-creation platform for the furniture industry based on a four-step business model innovation framework. This method will then be applied to a specific project scenario to derive a project-specific DIT co-creation business model. This generates knowledge about the collaborative manufacture of sustainable and customized furniture and contributes to the cross-sectoral transfer of platform business models for the development of sustainable products.
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.
Numerous start-ups and now even some major corporates are currently trying to improve visibility and foresight in the manufacturing industry through connected supply chains, or in other words, through increased data sharing. This study strives to support companies in leveraging the potential of increased data sharing in supply chain collaborations. Despite the great potential of digitizing manufacturing and automated data sharing throughout the supply chain, most companies are not yet able or willing to implement this kind of openness. The main reason for this lack of transparency in the supply chain is the high complexity and high cost of the required interfaces. In practice, instead of automated and extensive data sharing, companies exchange spreadsheets and PDFs with minimum information. This study supports companies in the pre-stage before automated data sharing is technically implemented. We find that building trustful relationships is a necessary step towards extended and automated data sharing. Moreover, we find that social capital provides a means to partially compensate for a lack of automation in terms of shortening lead times and dealing with disruptions. Introducing a supply chain collaboration typology and showcasing descriptive and qualitative results for 36 firms, we show how to navigate the frontend of the Internet of Production.
Um in komplexen Wertschöpfungsnetzwerken und an der Schnittstelle zwischen Kunden und Lieferanten valide, datenbasierte Entscheidungen treffen zu können, muss eine hohe Datenqualität vorliegen. Dabei mangelt es oft an einem Datenqualitätsmanagement (DQM), das den konkreten Anwendungsfall und den überbetrieblichen Austausch berücksichtigt. Wir stellen ein universales Rahmenwerk für das überbetriebliche DQM vor, das Ziele, Prozesse, relevante Daten und Akteure erfasst und den Grundstein für eine ganzheitliche Datenqualitätsstrategie legt.
Obwohl Sprachassistenzsysteme im privaten Alltag immer beliebter werden, finden solche Systeme noch kaum Anwendung in der Industrie. In der Theorie werden diverse Potenziale wie Zeiteinsparungen, verbesserte Ergonomie oder optimierter Informationsfluss durch den industriellen Einsatz von Sprachassistenten erwartet. Jedoch wurde dieser Einsatz im industriellen Kontext noch nicht praxisnah erforscht. Aus diesem Grund wurde im Rahmen des Forschungsprojektes „Smart Speaker“ eine Laborstudie durchgeführt, um den Einsatz von Sprachassistenzsystemen am Beispiel eines Montageprozesses zu untersuchen. Es konnten dabei drei wichtige Faktoren identifiziert werden, die maßgeblich die Nutzungseffizienz eines Sprachassistenzsystems beeinflussen.
Die verarbeitende Industrie in Deutschland steht vor der Transformation von der bisher vorherrschenden ökonomisch orientierten Produktion hin zu einer nachhaltigen Produktion. Durch die Anpassung von Parametern der Produktionsplanung und -steuerung, wie z. B. der Losgröße durch u. a. die Konsolidierung von Transportaufwänden oder geringe Reinigungsaufwände, kann dabei eine nachhaltigere Produktion erreicht werden. Hierfür wurde mittels einer systematischen Methodik ein digitaler Schatten konzeptioniert, der eine nachhaltige Konfiguration von Losgrößen ermöglicht. Dafür erfolgen eine Aggregation von Daten aus verschiedenen Informationssystemen und die Simulation des Verhaltens eines Produktionssystems bei veränderten Losgrößen. Diese ermöglichen eine optimierte Auslegung der Losgröße, basierend auf ökonomischen und ökologischen Zielgrößen.
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.
Eine wesentliche Bedingung zur Optimierung der Wertschöpfungsprozesse ist die Transparenz über die leistungsbestimmenden Faktoren eines Unternehmens. Die Ermittlung dieser Faktoren stellt für viele Industriebetriebe eine Herausforderung dar. Im Rahmen der Veröffentlichung wird daher eine Vorgehensweise zur systematischen Identifikation von Einflussfaktoren der Unternehmenskennzahlen vorgestellt, welche die Grundlage zur Ableitung von individuellen Stellhebeln zur Steigerung der Unternehmensleistungsfähigkeit darstellt.
Recent developments have demonstrated the challenges and impacts of disruptions in supply chains. Current disruptions especially affected procurement and have indicated a lack of resilience. Resilience aims at being prepared, decreasing the impact, and enabling fast reactions and adaption in case of disruptions. The systematic design of resilience in procurement is significantly influenced by proactive and strategic actions before disruptions occur. Thus, the procurement strategy plays a major role when increasing resilience. The procurement strategy is influenced by various factors. Thus, a data-based approach for its systematic design is required. Based on the vision of the Internet of Production (IoP), this paper presents a data-based approach for designing procurement strategies. The IoP is a framework that enables cross-domain collaboration by providing semantically adequate and contextual data from production, development, and usage in real-time at an appropriate granularity. The paper aims at analyzing the state of the art regarding the design of procurement strategy in uncertain environments and the identification of success-critical purchased articles. Based on this, an approach is developed that is structured along the action research cycle and uses CRISP-DM to further detail the different steps. Through the use of these frameworks, both practical applicability and objective evaluation are ensured. The proposed approach thus allows the systematic evaluation of purchased articles regarding supply risks and lies the foundation for the adaption of the procurement strategy. The resulting approach is the foundation for future practical application of different use cases. As one central use case for the presented approach, the paper introduces the textile industry and its supply chains.
