    Examining the PASS Approach to Process Modelling for Digitalised Manufacturing
    (Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 15, Nr. 1, 2022) Moser, Christoph; Kannengiesser, Udo; Elstermann, Matthes
    This article investigates whether an existing process modelling notation - the Parallel Activity Specification Scheme (PASS) - can support the digitalisation of manufacturing processes. In particular, four aspects are examined that have previously been claimed to be benefits of the PASS notation: ease of modelling, distributed modelling, incremental change, and IT integration. This is done by analysing three digital transformation projects in the manufacturing industry. The projects included the analysis and improvement of cross-department value streams, the introduction of Automated Guided Vehicles (AGVs) on the shopfloor, and the specification of a new Manufacturing Execution System (MES). The ways in which PASS was used and whether it was able to provide its claimed benefits are presented and analysed.

    Virtues and Values in Conceptual Modeling with Subject-Orientation
    (Modellierung 2024 Satellite Events, 2024) Elstermann, Matthes
    This work delves into the problem domain of modeling human values, specifically focusing on the subject-oriented paradigm. The goal of this workshop contribution is to explore the thought that the choice of modeling paradigm profoundly influences the expression and exchange of ideas/values with and within models and that Subject-Orientation, as a paradigm, possibly offers a unique and interesting foundation for that by leveraging its intrinsic ties to natural language structures. The work discusses the core tenets of Subject-Orientation, with its explicit consideration of active entities, and their relationships with passive elements and activities during modeling, especially of complex process systems as they are prevalent in the discussions of modern society. It then navigates through the implications of Subject-Orientation on expressing values, emphasizing the precision required in attaching values to specific entities as well as the paradigm’s impact on the inclusion of human elements in modeling. Furthermore, the exchange of values during the modeling process itself is explored, arguing that Subject-Orientation supports meaningful representations and facilitates the exchange of values among stakeholders. The explicit intent of this brief contribution is to spark discussions and especially encourage those unfamiliar with Subject-Oriented thinking to explore its advantages and drawbacks compared to modeling unrestricted by specific paradigms.
