Due to current agility requirements of organizations, socio-technical system development is considered one of the key activities of members of the organizations. Dynamic process adaptation enable handling the volatility of business operation and IT infrastructure. Subject-oriented process representations are key enablers to dynamic adaptation due to their capability for stakeholders to create directly executable models. In this way stakeholder can be involved in change management pro-actively. Subject-oriented models (i) represent all relevant features required for system control and decision making, and (ii) are executable on demand. This effectiveness enables organizational change in a creative and efficient way, while establishing innovative design and change management tools. Subject-oriented Business Process Management capabilities are reflected in this realm revealing benefits and potential for further research.}, language = {en} } @article{StaryElstermannFleischmannetal.2022, author = {Stary, Christian and Elstermann, Matthes and Fleischmann, Albert and Schmidt, Werner}, title = {Behavior-Centered Digital-Twin Design for Dynamic Cyber-Physical System Development}, volume = {2022}, pages = {169}, journal = {Complex Systems Informatics and Modeling Quarterly (CSIMQ)}, number = {30}, publisher = {Technische Universit{\"a}t Riga}, address = {Riga}, issn = {2255-9922}, doi = {https://doi.org/10.7250/csimq.2022-30.02}, pages = {31 -- 52}, year = {2022}, abstract = {Digital Twins are digital models of Cyber-Physical Systems to enable not only continuous monitoring but also active functional improvement of networked services, physical products, machines and devices. This capacity is of utmost importance when recognizing and exploring business opportunities in terms of organizational and technology innovations, as well as enriching the scope of system-relevant applications. Before being operated in their target ecosystems, such as smart cities, Cyber-Physical Systems can be validated and be run as Digital Twin through executable behavior models. The development of these models captures both, the horizontal, and the vertical integration of CPS components, thus allowing to consider specific system qualities, such as pollution effects of traffic. This article investigates methodological and technological aspects of developing and operating Digital Twins along system transformation processes. We consider integration depth and breadth, connectivity, organizational intelligence, validation, and implementation variability in the context of human-centered modeling and development. The approach enriches the understanding of digital twins towards digital representation of Cyber-Physical Systems allowing for dynamic allocation of physical and digital parts according to operational conditions. An exemplary case study in traffic management demonstrates the feasibility and practicability of the communication-centered approach.}, language = {en} } @article{FleischmannSchmidtStaryetal.2014, author = {Fleischmann, Albert and Schmidt, Werner and Stary, Christian and Augl, Martina}, title = {Agiles Prozessmanagement mittels Subjektorientierung}, volume = {50}, journal = {HMD Praxis der Wirtschaftsinformatik}, number = {2}, publisher = {Springer}, address = {Wiesbaden}, issn = {2198-2775}, doi = {https://doi.org/10.1007/BF03340797}, pages = {64 -- 76}, year = {2014}, language = {de} }
