    Controlled Run-Time Adaptivity in Industrial Agent Systems - Challenges and Research Prospects
    (INFORMATIK 2023 - Designing Futures: Zukünfte gestalten, 2023) Sudeikat, Jan; Köhler-Bußmeier, Michael
    Developing Cyber-physical Systems (CPS) inherently requires enabling run-time adaptivity. These systems integrate physical components, which operate in changeable contexts. In addition, objectives may change, due to socio-technical aspects. Industrial agents have been proposed for enhancing future industrial automation and control systems and integrating agents in industrial systems is an active field of research. Besides enabling technical compatibility of agent concepts and frameworks, the design and orchestration of agent activities have to be fine-tuned and a goal-directed adaption@run.time requires that the system can analyze its own structure at run-time; therefore, the system’s structure has to be reflected inside the system. Here, we outline current work and research challenges on how explicit organizational modeling can facilitate developing industrial agent systems. We discuss architectural aspects and outline how adaptations of organizations can be enabled, modeled and automated following the MAPE-K approach.

    Towards Integrating Multi-Agent Organizations in OPC UA for Developing Adaptive Cyber-Physical Systems
    (INFORMATIK 2022, 2022) Sudeikat,Jan; Kohler-Bußmeier,Michael
    Developing adaptive Cyber-physical Systems (CPS) requires integrating physical components with run-time controls which monitor and adjust the operation of components appropriately. The use of multiagent systems (MAS) is an established approach for embedding adaptive features and the integration of multiagent systems in industrial systems is an active field of research. Industry standards, like OPC UA, allow for vendor independent information exchange and unit control in industrial settings. Here, we propose to represent MAS organizations within OPC UA information models. The organization of a MAS can be seen as a crosscutting concern in structing and integration distributed adaptive applications. Explicit modelling allows to express organizational structures in industrial settings and enables monitoring of these structures at run- time with established tools and frameworks for industrial control.
