    Application-Architecture of an ERP-System for the era of Industry 4.0
    (INFORMATIK 2021, 2021) Herlyn, Wilmjakob Johannes
    In this paper we design an architecture of a future ERP-System that bases on the concept of a Digital Control Twin as its kernel. ‘Architecture’ in this paper means how the different applications of an ERP-System work together in combination with the Operation Control System of the Computer. The architecture is designed in the way that a lot of EPR-Applications are integrated in only one System. Nowadays the ERP-applications are separated modules like Master Production Scheduling and Manufacturing Execution or Material Requirement Planning, Warehouse Management, Transportation Control or JIT-Call-Offs which causes a loss of data consistency and accuracy and a lack of response-time and adjustment consequently. Classical ERP-Systems bases on the Waterfall-Model with no direct recursion of results to a preceding module. This architecture is no more suitable for the capabilities of industry 4.0 e. g. to exploit the huge amount of permanent available data and to react instantly on disturbances in production, transportation, storing or handling. The proposed architecture is a kind of Design Science Research approach that bases on the knowledge and experience in one of the biggest automotive OEM in the departments of IT, Purchasing, Production, Logistic and Sales.

    Digital Twin – Potenziale für die Polizei
    (INFORMATIK 2023 - Designing Futures: Zukünfte gestalten, 2023) Volkmann, Dirk; Schildein, Sabine; Povalej, Roman
    Für die moderne Polizeiarbeit haben Themen wie GIS, BIM, CAD, Digital Twin u. a. eine immer größer werdende Bedeutung. Neue Technologien helfen, polizeiliche Aufgaben effektiver und effizienter zu bewältigen. So kann ein Digital Twin z. B. bei der Bewältigung von Einsatzlagen, im ermittelnden Bereich bei On the Case oder Cold Cases die Polizeiarbeit nachdrücklich unterstützen. Allgemein ist das Ziel solch einer kriminalistischen Arbeit die Rekonstruktion und wahrheitsgetreue Repräsentation einer Tathandlung bzw. eines Tatgeschehens. Im Paper werden relevante Begrifflichkeiten betrachtet sowie Einsatzmöglichkeiten geografischer Informationssysteme unter Implementierung von Digital Twins als Referenzmodelle am Beispiel der Vernehmung aufgezeigt. Dabei wird auf die GIS- und BIM-Methoden reflektiert, die sich als vernehmungsunterstützende Elemente anbieten und einen enormen Mehrwert erzeugen können. Abgeschlossen wird das Paper mit einer Reflektion der gewonnenen Erkenntnisse hinsichtlich Bedeutung für die moderne Polizeiarbeit.

    Enhancing Digital Shadows with Workflows
    (Modellierung 2022 Satellite Events, 2022) Heithoff, Malte; Michael, Judith; Rumpe, Berhard
    The vast amount of data in modern manufacturing demands acquisition of contextualized data to enable fast decision making where domain expertise must be provided at run-time. Within this paper, we investigate the research question how to handle human-machine-interactions for engineering of digital shadows and still ensure the traceability of computation and simulation results. Current research for digital shadows concentrates on modeling key elements such as data sharing or metadata, but does not incorporate human-machine-interaction or the traceability of data aggregation. In this paper, we present a conceptual model which covers the base concepts for digital shadows integrating human-machine-interaction by utilizing workflows. We extend the conceptual digital shadow model defined within the “Internet of Production” excellence cluster and showcase our approach on an example. This contribution presents an applicable modeling approach for designing digital shadows which provide contextual information of the underlying human integrated process.

    Modeling Digital Shadows in Manufacturing by Using Process Mining
    (Modellierung 2022 Satellite Events, 2022) Brockhoff, Tobias; Uysal, Merih Seran; van der Aalst, Wil
    Friction in shopfloor-level manufacturing processes often occurs at the intersection of different subprocesses (e. g., joining sub-parts). Therefore, considering the Digital Shadows (DSs) of individual materials/sub-parts is not sufficient when analyzing the processes. To this end, holistic views on shopfloor-level processes that integrate multiple DSs are needed. In this work, we discuss how material-centric DSs supported by discrete assembly events can be integrated using techniques from process mining. In particular, we propose to utilize DSs that contain additional structural information to overcome the main challenges of concurrency and the presence of many different objects.

    Modelling Pig Rearing as Digital Shadow
    (Modellierung 2022 Satellite Events, 2022) Zimpel, Tobias
    Pig rearing and animal welfare are increasingly in the interest of society. To enhance animal welfare using data-driven analyses, modeling the pig rearing process is essential to create corresponding data sets. Pig rearing is a complex process for increasing pigs’ weight (from approx. five to 25 kilograms) involving various actors (e. g. farmers, veterinarians) to provide goods (e.g., food, water) and services (e.g., medical care). Thereby, pigs live in pens equipped with condition-measuring sensors, like the pen's temperature or pigs' activity. Manual measurements (e.g., weights) are also conducted, resulting in various data sources. For analyzing these data, measured in different contexts, a digital shadow appears as an approach for modeling these data traces. Therefore, we report on a digital shadow for pig rearing, including the assets pen and pig, sensor sources, data traces (e.g., pens’ temperature), and the purpose of analyzing causes of necrosis (dead tissue) with association rules.

    Workshop Modeling in (and for) Production
    (Modellierung 2022 Satellite Events, 2022) Michael, Judith; Koren, István
    The production domain is permeated by heterogeneous data sources, a variety of IT systems, and complex industrial use cases - aspects that offer an exciting field for research. The MoPro Workshop aims to be a platform for researchers and practitioners within the production domain to exchange their modeling techniques, interesting use cases, and challenges. We are interested in the use of models for development, production, and usage cycles, as well as model-based and model-driven approaches that span these domains across disciplinary boundaries.
