Produzierende Unternehmen stehen vor der Herausforderung, die Digitalisierung ihrer Systemlandschaften nutzenorientiert auszurichten. Aufgrund der oftmals historisch gewachsenen Shopfloors und IT-Systeme sind die Möglichkeiten mit den bereits existierenden Bestandssystemen undurchsichtig. Eine Vielzahl an Anwendungsfällen ist bereits mit geringem Mehraufwand, im Kontrast zu umfassenden Neuanschafungen, umsetzbar. Entscheidend ist eine systematische Ermittlung von Handlungsbedarfen, die auf den individuellen Bestandssystemen und Zielsetzungen basieren. Ziel des Forschungsprojekts ‚MarryIT‘ ist es, KMU durch eine methodisch angeleitete Erfassung und Bewertung des IT-OT-Integrationsstands zu unterstützen. IT-OT-Integration beschreibt die Vernetzung der Shopfloorsysteme (OT-Systeme wie MES, Produktionsmaschinen, Sensoren, Waagen, Scanner etc.) mit den Officefloorsystemen (IT-Systeme wie IoT-Plattformen, ERP, PLM, Supply-Chain-Management-Systeme etc.).
With the development of publicly accessible broker systems within the last decade, the complexity of data-driven ecosystems is expected to become manageable for self-managed digitalisation. Having identified event-driven IT-architectures as a suitable solution for the architectural requirements of Industry 4.0, the producing industry is now offered a relevant alternative to prominent third-party ecosystems. Although the technical components are readily available, the realisation of an event-driven IT-architecture in production is often hindered by a lack of reference projects, and hence uncertainty about its success and risks. The research institute FIR and IT-expert synyx are thus developing an event-driven IT-architecture in the Center Smart Logistics' producing factory, which is designed to be a multi-agent testbed for members of the cluster. With the experience gained in industrial projects, a target IT-architecture was conceptualised that proposes a solution for a self-managed data-ecosystem based on open-source technologies. With the iterative integration of factory-relevant Industry 4.0 use cases, the target is continuously realised and validated. The paper presents the developed solution for a self-managed event-driven IT-architecture and presents the implications of the decisions made. Furthermore, the progress of two use cases, namely an IT-OT-integration and a smart product demonstrator for the research project BlueSAM, are presented to highlight the iterative technical implementability and merits, enabled by the architecture.
Industry 4.0 is driven by Cyber-Physical Systems and Smart Products. Smart Products provide a value to both its users and its manufacturers in terms of a closer connection to the customer and his data as well as the provided smart services. However, many companies, especially SMEs, struggle with the transformation of their existing product portfolio into smart products. In order to facilitate this process, this paper presents a set of smart product use-cases from a manufacturer’s perspective. These use-cases can guide the definition of a smart product and be used during its architecture development and realization. Initially the paper gives an introduction in the field of smart products. After that the research results, based on case-study research, are presented. This includes the methodological approach, the case-study data collection and analysis. Finally, a set of use-cases, their definitions and components are presented and highlighted from the perspective of a smart product manufacturer.
