    Domain-Specific Conceptual Modeling
    (EMISA 2024, 2024) Paczona, Martin; Mayr, Heinrich C.; Prochart, Guenter
    This EMISA24 Current Research Talk is based on the authors' paper, recently published in the journal Data and Knowledge Engineering. We address the question of whether and how domain-specific modeling can increase productivity in the development of technical systems in an industrial setting. For, managers' decisions are ultimately based on whether or not the use of a new method pays off. The research was intertwined with a project in which we collaborated with a company to develop a domain-specific modeling method and tool for designing and implementing testbeds for electric vehicles.

    Model-Based Generation of Software Configurations in Mechatronic Systems
    (Modellierung 2020, 2020) Paczona, Martin; Mayr, Heinrich C.; Prochart, Guenter
    An essential part of the mechatronic system is the software, which is responsible to bring functionality into the system consisting of mechanical, electronic and electrical parts. The software must be tailored to the specific hardware to fulfill tasks (e.g. control, monitoring) according to the system requirements. In today‘s industrial practice, the design is mainly done manually. First the entire architecture is drawn using drawing tools. Based on this software developers derive the low-level specification using their low-level development environments. This is error prone and time-consuming due to the fact, that a large number of hardware parameters have to be taken in account and the informal specification does not allow to derive these parameters. To improve this we present here an approach where the overall architecture of the mechatronic system is described using a Domain-Specific Conceptual Modeling Language (DSML) using the example of Electric Vehicle Testbeds. Based on this model the low-level software configurations are generated rule-based. In this paper we present the concepts of the DSML, explain the transformation rules and show the functionality of the generator by introducing a practical example.

    Model-based Testbed Design for Electric Vehicles
    (40 Years EMISA 2019, 2020) Paczona, Martin; Mayr, Heinrich C.; Prochart, Guenter
    Electric cars boom. This puts pressure on providing and improving tools and systems for electric car development. Electric vehicle testbeds (EVTs) are such systems: they serve for testing all high voltage vehicle components like batteries, inverters or complete engines and help to reduce the need of cost intensive road tests. EVT users like manufacturers of automobiles, aircrafts or train engines mostly have individual requirements. EVTs are therefore typically tailor-made solutions. Today’s approach to customized testbed (component) design starts with drawing the overall architecture using tools like MS Visio; based here-on, software developers, circuit plan designers, and engineers use their specific low-level design and development environments, obviously with no transformation or generation out of the initial drawing with causes all known challenges of such procedure. This paper presents a novel, innovative and scalable approach to EVT design based on an ontology grounded Domain Specific Modeling Language (DSML). It enables the user to describe the customer requirements in the familiar form. The resulting model can then be used to generate circuit diagrams and software configurations. Such approach not only may reduce development time and cost but may increase the quality of the resulting EVT.
