- Konferenzbeitrag50 Jahre Verhaltensmodellierung: Vom Modellieren mit Programmen zum Programmieren mit Modellen(Modellierung 2010, 2010) Reisig, WolfgangSoftware entwickeln bedeutet, die Kluft zwischen algorithmischen Ideen und implementierten Programmen zu überbrücken. Dabei helfen Modelle: Ein adäquates Modell einer algorithmische Idee repräsentiert die relevanten Aspekte der Idee verständlich und unmittelbar einsichtig. Ein gutes Modell vermeidet Zusätze oder Abstriche, die lediglich der verwendeten Modellierungstechnik geschuldet wären. In diesem Beitrag konzentrieren wir uns auf Modelle zur Beschreibung des dynamischen Verhaltens von Systemen. Während „Datenmodellierung“ ein aus der Datenbanktheorie wohlbekanntes Konzept ist, gibt es für das Modellieren von Verhalten keinen gleichermaßen etablierten Begriff. Ein solcher Begriff würde weit mehr als den Kontrollund Datenfluss umfassen und auch generelle Fragen an das Konzept des „Algorithmus“ stellen. Eine Modellierungstechnik stellt Ausdrucksmittel bereit, um eine spezifische Art von Modellen zu charakterisieren. Eine zweckmäßige Modellierungstechnik bietet außerdem ausdrucksstarke Verfahren zur Analyse dieser Modelle, d.h. zum Nachweis spezieller Eigenschaften. Wir konzentrieren uns hier auf Techniken zur Verhaltensmodellierung, die ausdrucksstarke Analyseverfahren bereitstellen. Wir streifen ihre historische Entwicklung, versuchen eine Klassifikation solcher Techniken gemäß signifikanter Kriterien, und fragen nach den wichtigsten Gestaltungsprinzipien zukünftiger Modellierungstechniken.
- KonferenzbeitragAccessibility in Conceptual Modeling Research and Tools(Modellierung 2024, 2024) Sarioglu, Aylin; Metin, Haydar; Bork, DominikThe reports on Disability by the World Health Organization show that the number of people with disabilities is increasing. Consequently, accessibility should play an essential role in information systems engineering research. While software and web engineering research acknowledge this need by providing, e.g., web accessibility guidelines and testing frameworks, we show in this paper, based on a systematic review of the literature and current modeling tools, that accessibility is, so far, a blind spot in conceptual modeling research. With the paper at hand, we aim to identify current research gaps and delineate a vision toward more inclusive, i.e., disability-aware conceptual modeling. One key finding relates to a gap in research and tool support concerning physical disabilities. Based on these results, we further present the first modeling tool that can be used keyboard-only, thereby including users with physical disabilities to engage in conceptual modeling.
- KonferenzbeitragAdaptable Model Versioning in Action(Modellierung 2010, 2010) Brosch, Petra; Kappel, Gerti; Seidl, Martina; Wieland, Konrad; Wimmer, Manuel; Kargl, Horst; Langer, PhilipIn optimistic versioning, multiple developers are allowed to modify an artifact at the same time. On the one hand this approach increases productivity as the development process is never stalled due to locks on an artifact. On the other hand conflicts may arise when it comes to merging the different modifications into one consolidated version. In general, the resolution of such conflicts is not only cumbersome, but also error-prone. Especially if the artifacts under version control are models, little support is provided by standard versioning systems. In this paper we present the enhanced versioning process of the model versioning system AMOR. We show how AMOR is configured in order to obtain a precise conflict report which allows the recommendation of automatically executable resolution patterns. The user of AMOR chooses either one of the recommendations or performs manual resolution. The manual resolution may be in collaboration with other developers and allows to infer new resolution patterns which may be applied in similar situations.
- KonferenzbeitragAdditional Information in Business Processes: A Pattern-Based Integration of Natural Language Artefacts(Modellierung 2014, 2014) Bittmann, Sebastian; Metzger, Dirk; Fellmann, Michael; Thomas, OliverBusiness process modelling initiatives frequently make use of semi-formal modelling languages for depicting the business processes and their control flows. While these representations are beneficial for the analysis, simulation and automatic execution of processes, they are not necessarily the best option to communicate process knowledge required by employees to execute the process. Hence, textual process representations and their transformation to semi-formal models gain importance. In this paper, a pattern-based modelling approach positioned in between the two extremes of informal text and semi-formal process models is derived. The patterns offer a basis for a seamless integration of natural language and business process models. In particular the business process modelling patterns, which have to rely on human interactions are focussed. For those patterns an integrated representation of information that support the manual execution is developed. The approach fosters the contribution by employees of the operative business, since it does not rely on classical modelling paradigms, but uses natural language for modelling business processes.
- KonferenzbeitragAdvancing Virtual Coaching in Healthcare: Towards A Unified Terminology and Reference Model(Modellierung 2024, 2024) Gißke, Carola; Weiman, Thure Georg; Schlieter, HannesVirtual coaching applications, designed to facilitate behavior change through adaptive coaching activities, hold promise for personalized interventions, particularly in healthcare. While existing literature explores various aspects of virtual coaches (VCs), there is a lack of comprehensive conceptual analysis, and inconsistent terminology further complicates their understanding. The present paper aims to demonstrate the ongoing work on systematically categorizing and describing the components of VCs and, thereby, creating a reference model reusable for different contexts. Based on a systematic literature review, concepts related to VC interventions will be derived, categorized, and linked to each other, forming a unified framework that could simplify the process of designing VCs and provide the foundation for dedicated building tools in terms of low/no-code platforms. Moreover, the work contributes with a consolidated terminology, and the proposed model may also be used to identify underexplored research areas, enhancing research opportunities in the field.
- KonferenzbeitragAn agile approach to workflow management(Modellierung 2004, 2004) Weber, Barbara; Wild, WernerIn today's dynamic and uncertain business environment workflow management systems must react quickly to change. This paper suggests extending workflow management with case-based reasoning (CBR) to allow just-in-time updates to the predefined workflow model and to provide flexibility by keeping (real) options open rather than freezing them early on. First an initial workflow model is created, covering only the economically justifiable details of a business process. The decision how to model a business process precisely is delayed until the company's needs are more clearly understood and business value can be achieved. When changes become necessary during run-time, the predefined workflow model is extended with additional knowledge in the form of cases. This feedback supports continuous process improvement, resulting in more manageable and more efficient business processes over time. When the knowledge encoded in cases becomes frequently reused, it is refactored into rules and therefore explicitly included in the workflow model.
- KonferenzbeitragAgility in medical treatment processes – a model-based approach(Modellierung 2012, 2012) Burwitz, Martin; Schlieter, Hannes; Esswein, WernerThe economic view on today's health care organizations insists on the integration of standardized process descriptions by Clinical Pathways and information technology (IT). The individuality of several treatments then again requires mechanisms for a flexible and agile alignment oft a treatment process at any time. This paper delineates an IT-system for an agile execution of medical treatment processes based on process models of Clinical Pathways. It will be shown which information occurs and where it can be used in terms of an agile process management and a continuous process improvement.
- KonferenzbeitragAnalysis of Business Process Model Reuse Literature: Are Research Concepts Empirically Validated?(Modellierung 2014, 2014) Fellmann, Michael; Koschmider, Agnes; Schoknecht, AndreasBusiness process modeling is a highly manual task. The effort of business process modeling might be reduced if process modelers are provided with the option of reusing existing process model assets instead of creating new models from scratch. Numerous research efforts thus have been focused on the reuse of existing model assets leading to a great variety of methods, models, algorithms and tools. However, up to now, the state of empirical evidence in respect to proven positive effects using these approaches is largely unclear. We therefore fill this gap by systematically analysing the available publications. Our paper contributes to the understanding of business process model reuse and consequently also to the knowledge base regarding process model reuse.
