    In diesem Artikel wird die Notwendigkeit eines Paradigmenwechsels hin zu einer nachhaltigeren Upgrade-Kreislaufwirtschaft erörtert. Der Fokus liegt dabei auf der Bedeutung der Umsetzung umfassenderer Maßnahmen anstatt einzelner isolierter Ansätze. Es wird die Green Upgrade Re-Assembly Factory als Lösung für die nachhaltige Aufwertung komplexer Massenprodukte für mehrere Lebenszyklen vorgeschlagen. Der Artikel zeigt die Herausforderungen der Re-Assembly-Prozesse auf (z. B. Unsicherheiten bei der Qualität der Rückläuferprodukte sowie mangelnde Nachhaltigkeitstransparenz) und schlägt Lösungen wie die digitale Produktakte und flexible und anpassungsfähige Prozessdesigns vor. Darüber hinaus wird in dem Artikel dargelegt, dass auch eine Transformation von Produktionsgebäuden in langlebige sowie klimaneutral und ressourceneffizient betreibbare grüne Fabriken notwendig ist. Anhand namhafter Industriebeispiele wird gezeigt, dass sowohl die Umstellung eines Unternehmens auf einen zirkulären Produktionsansatz als auch der Umbau einer Fabrik zu einer Net-Zero-Fabrik profitabel gelingen kann - bereits unter den heutigen Bedingungen.

    Durch einen Fokus auf Recycling, geringere Energieverbräuche und verminderten Einsatz umweltschädlicher Rohstoffe kann die Nachhaltigkeit nur bis zu einem gewissen Grad gesteigert werden und erfordert meist die Kompensierung damit einhergehender Kosten. Ein Umdenken und eine radikale Transformation der Wertschöpfung hin zur Zirkularität bieten demgegenüber ökonomische Potenziale, die den Status-Quo deutlich übersteigen. Der Hebel dafür, ist die aktive Verlängerung von Kreisläufen und die Wertsteigerung durch das Upgraden von Produkten während der Nutzungsphase. Dies schafft die Möglichkeit der kontinuierlichen Monetarisierung von Upgrade-Potenzialen, während eine ressourcenausschöpfende Wertsteigerung über die Lebenszyklen eine ganzheitliche ökologische Nachhaltigkeit erreichbar macht. Schlüssel zu diesem Paradigmenwechsel liegen in der Produktmodularisierung und Technologieplanung. Zur Realisierung kreislauffähiger Produkte müssen diese verstärkt integriert und synchronisiert werden. Um heute und morgen ökologische und ökonomisch nachhaltige Leistungen anzubieten, ist ein Verständnis über Märkte und Kunden der Circular Economy notwendig. Außerdem erfordern die regelmäßigen Upgrades ein frühzeitiges Antizipieren relevanter Technologiesprünge. Unter Berücksichtigung dieser beiden Blickrichtungen muss eine Produktarchitektur für kreislauffähige Produkte entwickelt und die Technologiebetrachtung vertikal (um Re-X-Technologien) sowie horizontal (um Remanufacturing und Modul-Upgrades) erweitert werden.

    By focusing on recycling, lower energy consumption and reduced use of environmentally harmful (raw) materials, sustainability can only be increased to a certain extent and usually requires compensation for the associated costs. In contrast, a change in thinking and a radical transformation of the value creation towards a circular economy offer superior ecological and economic potential. This is realized by an active extension of utilization cycles and the continuous increase of product value through upgrades during the utilization phase, creating the possibility of recurring monetization. Accordingly, the key to this paradigm shift lies in a new product modularization for the realization of a circular economy and in an extended technology planning to anticipate the required flexibility and upgrades. Therefore, the goal of modularization is no longer the realization of economies of scale but enabling the value-enhancing extension of product lifetimes through module upgrades and replacements. This means that technology planning should no longer focus exclusively on new products, but in particular also on upgrades for existing products. As a consequence, holistic circularity roadmaps are emerging instead of roadmaps for individual products.

    The value-enhancing circular economy is a concept for the sustainable production of Goods. A central aspect of the value-enhancing circular economy is the reduction of the ecological footprint. At the same time, successful implementation of the concept supports accomplishing of targets in the dimensions of economic efficiency and innovation. A consistently aligned value-enhancing circular economy eliminates the ecologically negative consequences of production and increases the long-term value creation and profitability of the companies involved. This paper motivates and explains the concept of the value-enhancing circular economy. In addition, a framework is presented that supports companies in the transformation process towards it. For this purpose, the product architecture, the business model as well as the innovation and value creation strategy are detached from the paradigms of the established linear economy and oriented towards value enhancement and longevity. In order to ensure that all stakeholders have access to the information required for their participation, the digital shadow in the Internet of Sustainable Production is necessary. For the extended product life cycle, a digital product file acts as a digital shadow, bundling and aggregating all relevant information.

    This article discusses the need for a paradigm shift towards a more sustainable circular upgrade economy, highlighting the importance of implementing comprehensive measures instead of isolated approaches. It proposes the Green Upgrade Re-Assembly Factory to sustainably upgrade complex mass-produced products for multiple life cycles without compromising their performance and attractiveness. The article identifies the challenges faced in re-assembly processes, such as uncertainties in the quality of return products and lack of sustainability transparency. It suggests solutions such as the Digital Product Record and flexible and adaptable process designs. Furthermore, transforming production buildings into climate-neutral green factories designed to have the longest possible life cycle and most resource-efficient operation is necessary. Using prominent industrial examples, the authors show that both the transformation of a company to a circular production approach and the transformation of a factory to a climate-neutral green factory can succeed profitably - already under today's conditions.

    Die wertsteigernde Kreislaufwirtschaft ist ein nachhaltiges Konzept für die Produktion von Waren. Ein zentraler Aspekt der wertsteigernden Kreislaufwirtschaft ist die Reduzierung des ökologischen Fußabdrucks. Gleichzeitig ermöglicht die erfolgreiche Umsetzung des Konzepts auch eine Zielerfüllung in den Dimensionen der Wirtschaftlichkeit und Innovation. Eine konsequent ausgerichtete wertsteigernde Kreislaufwirtschaft eliminiert die ökologisch negativen Konsequenzen der Produktion und erhöht die Wertschöpfung und Profitabilität der beteiligten Unternehmen langfristig. Der vorliegende Beitrag motiviert und erklärt das Konzept der wertsteigernden Kreislaufwirtschaft. Zudem wird ein Framework präsentiert, welches Unternehmen bei der Transformation unterstützt. Dafür werden sowohl die Produktarchitektur, das Geschäftsmodell sowie die Innovations- und Wertschöpfungsstrategie von den Paradigmen der etablierten, linearen Wirtschaft gelöst und auf eine Wertsteigerung und Langlebigkeit ausgerichtet. Damit alle Stakeholder die zur Partizipation notwendigen Informationen abrufen können, wird der digitale Schatten im Internet of Sustainable Production als Basis für die Realisierung miteingebunden. Für den verlängerten Produktlebenszyklus fungiert zudem eine digitale Produktakte als digitaler Schatten, in dem alle relevanten Informationen gebündelt und aggregiert werden.

    Disruptive innovations are putting incumbent manufacturing companies under increasing pressure to defend their competitive position in globalized markets. To withstand this pressure, they can form cooperation agreements with startups aiming for the creation of technical innovations and, thus, ensuring access to technologies and growth. Due to organizational differences and an insufficient explication of cooperation objectives, these cooperation pose a major challenge for both partners. In this paper, the authors discuss the status-quo in the formation of entrepreneurial target systems and, thereby, systematically derive corporate as well as startup-specific cooperation deficits. Based on the analysis of creating individual target systems, a first attempt is taken to elaborate requirements for the development of a model to form collective target system for the cooperation between corporates and startups. Subsequently, model characteristics for the derivation of joint targets and requirements are discussed to enable a comparison between corporates and startups. The development of a concept for a requirements comparison based on a collective cooperation target system supports corporates and startups to ensure the fulfilling of the competitive advantage.

    The importance of job shop production is increasing in order to meet the customer-driven greater demand for products with a larger number of variants in small quantities. However, it also leads to higher requirements for the production planning and control. In order to meet logistical target values and customer needs, one approach is the focus on dynamic planning systems, which can reduce ad-hoc control interventions in the running production. In particular, the release of orders at the beginning of the production process has a high influence on the planning quality. Previous approaches used advanced methods such as combinations of reinforcement learning (RL) and simulation to improve specific production environments, which are sometimes highly simplified and not practical enough. This paper presents a practice-based application of an automated order release procedure based on RL using the example of real-world production scenarios. Both, the training environment, and the data processing method are introduced. Primarily, three aspects to achieve a higher practical orientation are addressed: A more realistic problem size compared to previous approaches, a higher customer orientation by means of an objective regarding adherence to delivery date and a control application for development and performance evaluation of the considered algorithms against known order release strategies. Follow-up research will refine the objective function, continue to scale-up the problem size and evaluate the algorithm’s scheduling results in case of changes in the system.

    Concept for Effective Identification and Initiation of Startup Investments for the Digital Transformation of Manufacturing Companies
    ( 2023)

    The digital transformation is fundamentally disrupting established business models and existing value chains at an accelerating pace. Faced with multidimensional and inevitable changes, many incumbent companies lack necessary competences, processes, and structures to actively transform their business with sufficient speed and extent. While successful tech-companies therefore consequently rely on startup acquisitions, investments or cooperations, most incumbent manufacturing companies are not successful in systematically leveraging external corporate venturing as a catalyst for their digital transformation. Several reasons may already be found in the early phases of an investment. This applies especially to the identification of suitable startups, the determination of the potential value contribution of an investment, and the effective initiation of startup investments. Against this background, this paper presents a concept for effectively identifying and initiating external corporate venturing initiatives for the digital transformation of manufacturing companies. Thus, existing approaches in literature are discussed and analyzed to derive the requirements for developing a concept, which enables effectively identifying suitable startups for digital transformation objectives and subsequently initiating an investment. Based on these findings, the methodology and its sub-models are derived.

    Performing business processes are a critical asset for manufacturing companies operating on highly competitive markets. Conventional approaches to business process improvement, however, are vulnerable to subjectivity and high manual efforts in their execution. These challenges can be overcome with recent databased approaches that semi-automate process analysis and design. Those approaches formalize methodical knowledge on weakness detection, measure derivation and performance evaluation for business processes into a performance-related decision support. By enabling the databased automation of these tasks this formalization helps to reduce efforts and subjectivity in process analysis and design. However, practice lacks a procedure for applying this decision support in operative business process improvement. Moreover, this decision support only formalises methodological knowledge. Operative business process improvement in practice additionally requires the consideration of experts’ contextual knowledge about the company and the business process itself. This paper presents a hybrid approach for the analysis and design of business processes using a databased decision support. First, existing phase models for business process improvement are consolidated into a reference model. Second, an expert-based assessment is conducted on how decision support extends, modifies or eliminates the conventional tasks of process analysis and design. In the third step, a hybrid phase model for process analysis and design is developed that integrates the formalised methodological knowledge of the decision support and contextual knowledge of experts.
