    A Classification Framework for Service Modularization Methods
    (Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 13, Nr. 14, 2018) Pöppelbuß, Jens; Lubarski, Aleksander
    Service modularity has been suggested as a promising concept that can resolve the dilemma between increasing diversification of customer demands and the provider’s need for standardization and efficiency gains. Despite having been in the center of attention amongst service researchers for the past decade, service modularity still remains a rather theoretical concept with little application in practice. Previous publications have contributed conceptual and enterprise modeling methods to achieve modular service architectures by both adjusting product modularization methods to the service domain as well as designing new ones specifically for services. However, up to date, there exists no framework that would systematize and classify these methods concerning their premises as well as underlying modularity principles and objectives. The main contribution of this paper is the development of a framework that can be used to classify existing and future methods for service modularization based on two key dimensions, i. e., the phases of the modularization process and the types of structuring the modular architecture. The developed framework further points out which phases of the overall modularization process are still underdeveloped and how future research can contribute to making service modularity more accessible for practitioners.

    Modularization Guidelines to Support Control Software Variability in IEC 61499
    (SE 2024 - Companion, 2024) Sharma, Shubham; Hager, Anna-Lena; Zoitl, Alois
    In the field of Cyber-Physical Production System (CPPS), a substantial number of control software components are integrated with legacy software. This legacy control software has existed in industries for decades and faces maintenance problems due to sub-optimal tool support. Consequently, rigid software structures have emerged, making maintenance difficult and necessitating better support for managing variability. These legacy systems contain an enormous volume of control software, making it impractical to transform manually in terms of variability management. Additionally, there is a growing demand for variability to accommodate to customer-specific requirements. Control software must be flexible and modular enough to fulfill diverse project-specific needs. Guidelines are required to assist control system engineers in determining which control software components must be refactored and which can be left unchanged. We investigated legacy control software from industrial use cases, identified problem areas, and gathered lessons learned. These lessons have been translated into guidelines for future control software modularization. Hence, in this paper, we present a set of guidelines aimed at modularizing IEC 61499 control software, specifically focusing on enhancing control software variability for variability-intensive CPPS.
