Integrating knowledge is crucial for open innovation, and digital technologies can play a central role because they support knowledge sharing. In open innovation projects, in particular, little is known about the role of technology. Here, the individual behaviour of users is taken into account concerning the extent to which knowledge is shared. Therefore, persuasive technologies offer the potential to foster sharing. In particular, to facilitate the construction of future digital technologies, this study applies a design science research approach to create and analyse artefacts as a research contribution and develop design principles as a step towards a nascent design theory. We present insights from the design and application of three artefacts in different stages of open innovation processes. Results show that digital technologies can be used for various purposes: to build a common understanding, support design phases, communicate ideas and simplify the application of the technology for the user. Our research provides insights into the role of digital technologies for knowledge sharing in open innovation projects, and four design principles are found to facilitate the construction of future persuasive digital technologies for open innovation projects.

Due to increasing complexity on the shop floor associated with the digital transformation and growing penetration of modern production environments with smart services, the operational phase of automated production facilities is gaining additional importance. The growing range of hybrid service bundles, i.e., the combination of digital services and cyber-physical production systems (CPPS), is expanding the scope of utilization and requires the application of platformbased solutions for service integration. Efficient, scalable IT infrastructures as well as technological flexibility and independence are premises for the successful implementation of these platforms. The availability of ubiquitous communication for seamless networking of all entities also plays a central role. These prerequisites enable the vertical integration of automation components on the shop floor up to the context of strategic business processes based on continuous data and information models. This paper presents an approach for integrating CPPS elements into scalable, highly available service platforms and shows how modern control approaches can be successfully linked with smart service concepts. The exemplary use case for this is a test bench for electric drives.

Die digitale Transformation verändert industrielle Wertschöpfung umfassend und nachhaltig. Dieser disruptive Prozess hat u. a. große Auswirkungen auf die Arbeitsformen, Rollen und Qualifikationsanforderungen in der Produktion sowie in vor- und nachgelagerten Wertschöp-fungsstufen. Neben Handlungs-, Fach- und Methodenkompetenzen in der Industriearbeit kommt der generellen Themenkompetenz bezüglich Industrie 4.0 eine immanent wichtige Rolle zu, wenn es darum geht, die Partizipation und Mitbestimmung jeder einzelnen Person an der digitalen Transformation industrieller Wertschöpfung sicherzustellen. Ebenso gilt es, integrative und Stakeholder-zentrierte Systementwicklungsverfahren zu etablieren, um die Einstellungen und Erwartungshaltungen verschiedener Stakeholder-Gruppen zu erfassen und moderieren sowie Konflikte zu regulieren und so letztendlich eine hohe Akzeptanz und An-nahme digitaler Technologien und Prozesse sicherzustellen. Dieser Beitrag analysiert und er-örtert die Eignung und Einsatzmöglichkeiten von Industrie 4.0-Demonstratoren zu diesen Zwe-cken. Im Zentrum der Betrachtung steht dabei der Portable Industrial Demonstrator for Cyber-Physical Systems (PID4CPS), der eine etablierte Instanziierung dieser Demonstratorenart dar-stellt. Besonderes Augenmerk wird auf die Verwendbarkeit von Industrie 4.0-Demonstratoren für die Lehr-/Lern- sowie Aus- und Weiterbildungszwecke in den unterschiedlichen Stufen des Bildungswesens gelegt. Darüber hinaus erfolgt eine vergleichende Gegenüberstellung der Konzepte von Industrie 4.0-Demonstratoren und Lernfabriken, aus der konkreten Handlungs-implikationen zum Einsatz dieser in Lehre sowie Aus- und Weiterbildung abgeleitet werden.
Increasing complexity in production and factory automation represents a significant challenge in context of maintenance. One approach to address complexity is the implementation of automated industrial service bundles, which resemble complex business processes. To enable efficient usage of service bundles, their individual components are designed as functional modules in the form of independent micro services and are compatible with the paradigm of service-oriented architectures. For ubiquitous communication and data exchange between service entities, message-oriented middleware provides an adequate solution. This paper presents an approach for increasing efficiency in maintenance using a service bundle. The use case demonstrates the automated creation of service tickets enriched with necessary information from various sources.

The application of models and simulations is well-established in systems engineering and development. To adapt this approach to the digital age, we propose the concept of “cyber-physical modeling and simulation (CPMS)” which enables to constitute cyber-physical systems (CPS) with scalable complexity, modularity and variability in size. Based thereon, we derive a reference architecture for designing demonstrators for industrial CPS. The reference architecture offers a structured design space and attributed components which constitute the demonstrators with regard to their application objectives and scenarios. As a viability assessment, we apply the proposed reference architecture by developing the instantiation “Portable Industrial Demonstrator for Cyber-Physical Systems (PID4CPS)”.

With the implementation of cyber-physical production systems, a multitude of isolated industrial services utilizing versatile hardware and software components in heterogeneous and rigid system architectures are an obstacle for the consequent extension of holistic automation within production networks. To address this issue, we conceptualize a platform-based system architecture enabling value-adding service bundles based on and extending proven architectural styles. Our proposal also aims on qualifying communication systems to work transboundary in value-adding networks. The presented architecture is applied to a use case in context of maintenance. Our findings provide an adaptive conceptualization for application-specific service composition and integration.

Zusammenfassung Architekturbegriffe spielen in der Wirtschaftsinformatik eine immer prominentere Rolle. Ein Beleg dafür ist der Begriff der Referenzarchitektur, welcher in einer stetig ansteigen Anzahl an Publikationen verwendet wird. Besonders im Kontext des Begriffs „Industrie 4.0“ und unternehmensübergreifenden Digitalisierungsbestrebungen wird der Begriff der Referenzarchitektur verstärkt verwendet, um auf eine gewisse Art der Standardisierung hinzuwirken und die Komplexität bei der Entwicklung von Systemen zu reduzieren. Jedoch ist die Verwendung des Begriffs und das Begriffsverständnis sehr heterogen, sodass der Vergleich, die Bewertung, eine Ableitung oder das Erstellen von Referenzarchitekturen sehr erschwert wird. Um solchen Herausforderung zu begegnen wird in diesem Beitrag das Begriffsverständnis von Referenzarchitekturen systematisiert, mit dem Ziel, eine einheitliche Grundlage für dessen Beschreibung und zum Vergleich von Referenzarchitekturen bereitzustellen. Hierzu werden geläufige Definitionen in Wissenschaft und Praxis dargelegt, diskutiert und an Hand der verfolgten Ziele sowie den Ausprägungen und Eigenschaften von Referenzarchitekturen systematisiert. Diese Systematik bildet dabei die Basis um auch zukünftige Begriffe und Eigenschaften im Kontext von Referenzarchitekturen einzuordnen bzw. zu klassifizieren.

The digitization of the industry offers far-reaching potentials in the context of industrial value creation. With the introduction of technologies such as cyber-physical systems (CPS), organizations aim to realize them. However, due to an increase in complexity with regard to system architectures and the number of involved stakeholders, organizations face novel challenges in the process of system development. This research addresses this issue with the de-sign of a portable industrial demonstrator for CPS and a complementary work-shop setting to model and simulate industrial CPS configurations with reduced complexity. Thereby, the solution functions as a boundary object joining differ-ent stakeholder groups to mediate and elaborate a common understanding, moderate conflicting expectations, evaluate and align system configurations and foster stakeholder driven innovations within the system design process. In doing so, the solution offers a new approach for participatory CPS design. The de-signed artifacts are evaluated in the course of interview and observational stud-ies in combination with focus groups. The results reveal that the development of industrial CPS benefits from the use of demonstrators, especially with regard to stakeholder integration.
The increasingly progressive digitization of industrial value creation in the context of the fourth industrial revolution is leading to profound change for companies. In this context, technological innovations like industrial cyber-physical systems (CPS) have an impact not only on production processes and service provision but also on the roles and activities of the most diverse actors in the internal and external environment of companies. For the sustainable and successful application of these technologies, it is therefore important to ascertain and analyze the expectations from and attitudes towards industrial CPS of the individual stakeholder groups in order to use this knowledge for the design, implementation and operation of industrial CPS configurations. Utilizing technology acceptance, innovation diffusion and stakeholder theories as a foundation, stakeholder groups are identified and subsequently surveyed via interviews and focus groups within a multiple case study. The subsequent evaluation of the data is based on a qualitative content analysis. The application of an industrial CPS for maintenance in companies within the automotive, supplier and power generation industries sets the empirical field. The results of the study offer a comprehensive overview of stakeholder expectations from and attitudes towards industrial CPS and show existing consensus but also the prevailing discrepancies.

The extensive digitization in industry and the advancing introduction of cyber-physical systems (CPS) in manufacturing offer a wide-ranging potential for industrial value creation. To ensure effective engineering processes of these systems, technological and organizational challenges need to be addressed systematically. Thereto, we develop a method for the systematic engineering of industrial CPS in this paper. The operational framework of the suggested method provides a guided process for (1) the selection of application fields for industrial CPS under the consideration of economic and technological necessities as well as (2) guidelines for the subsequent system configuration with components and functionalities.
