    A DSS based on ecological-economic modelling to facilitate the implementation of biodiversity offsets and agri-environment schemes in grasslands
    (42. GIL-Jahrestagung, Künstliche Intelligenz in der Agrar- und Ernährungswirtschaft, 2022) Sturm, Astrid; Waetzold, Frank; Westphal, Luise; Querhammer, Lisa
    In Europe, the decline of biodiversity is primarily a result of agricultural intensification. Especially grasslands show an increasingly poor conservation status whereas – if appropriately managed – extensive grasslands belong to the species-richest habitats in Europe. We present DSS-Ecopay AllerGruen®, a further development of the previous versions of DSS-Ecopay®. DSS-Ecopay AllerGruen® is based on a spatiotemporally explicit ecological-economic modelling procedure to assess the ecological effectiveness and cost-effectiveness of grassland measures on species and habitats. It is designed for small-scale regional applications as a tool to support the planning of grassland measures but also to be used in consultations with stakeholders by a local conservation foundation and the local nature conservation authorities. The software can be utilized to analyze the cost-effectiveness and ecological effectiveness of over 2000 grassland measures on target species and habitats for designing biodiversity offsets and agri-environment schemes.

    Exploring Architectural Design Decisions in Industry 4.0: A Literature Review and Taxonomy
    (Software Engineering 2022, 2022) Terzimehić, Tarik; Dorofeev, Kirill; Voss, Sebastian
    Paper accepted in the Foundation Track of ACM/IEEE 24th International Conference on Model Driven Engineering Languages and Systems (MODELS), 2021. Architectural design decisions, such as service deployment and composition, plant layout synthesis, or production planning, are an indispensable and overarching part of an industrial manufacturing system design. In the fourth industrial revolution (Industry 4.0), frequent production changes trigger their synthesis, and preferably optimization. Yet, knowledge on architecture synthesis and optimization has been scattered around other domains, such as generic software engineering. We take a step towards synthesizing current knowledge on architectural design decisions in Industry 4.0. We developed a taxonomy describing architectural models, design decisions, and optimization possibilities. The developed taxonomy serves as a guideline for comparing different possibilities (e.g., application of different optimization algorithms) and selecting appropriate ones for a given context. Furthermore, we reviewed and mapped 30 relevant research works to the taxonomy, identifying research trends and gaps. We discuss interesting, and yet uncovered topics that emerged from our review.

    Generating an Environment for Socializing Between Older Adults in a VR Supermarket
    (INFORMATIK 2023 - Designing Futures: Zukünfte gestalten, 2023) Walchshäusl, Sebastian; Eichhorn, Christian; Plecher, David A.; Simecek, Tim; Klinker, Gudrun; Hiyama, Atsushi; Inami, Matsuko
    Socialization is crucial for the well-being of individuals, but elderly people often face challenges due to physical and psychological issues, as well as the COVID-19 pandemic. To address this issue, a novel approach has been developed using a Japanese Virtual Reality (VR) supermarket, where older adults can purchase products that could be delivered to their homes while socializing with others in a familiar environment. The VR supermarket is based on Japanese supermarket shelf layouts, with hand-tracking and gestures used for interaction. Avatars, attached with images of the participants and their synchronized voice input are used to represent them. In a user study involving 14 older adults, the application was found to be effective for social communication, and potential negative effects such as cybersickness were successfully mitigated. The VR supermarket thus provides a valuable tool for older adults to socialize and meet their need to interact with people from the same age group, even in isolation (pandemic scenario).

    A Use Case Analysis assessing Process Mining Model Quality for Simulation
    (AKWI Jahrestagung 2024, 2024) Schmolke, Marianne; Jawad Javaid, Muhammad
    Ever-evolving business processes can be re-engineered with process mining and simulation as a technology, as the approach shapes future outcomes, analyzing their present and past. Developing effective models can make it easier and more cost-effective, as there are potential benefits such as working with what-if scenarios and eliminating bottlenecks, but their quality check is always an issue. Different criteria have been applied to tackle this quality issue, disclosing expected benefits and weaknesses. This can help build suitable ground for analyzing and implementing relevant use cases. The criteria extracted from process model quality research demonstrate the effectiveness of model assessment and have practical implications for improving use case modeling. Results display the quality of particular models and indicate how use case modeling can be improved.
