This study introduces a methodology integrating Life Cycle Assessment (LCA) with Failure Mode and Effects Analysis (FMEA) to identify and assess environmental sustainability risks in manufacturing processes in alignment with the Corporate Sustainability Reporting Directive (CSRD) and European Sustainability Reporting Standards (ESRS). In contrast to existing top-down approaches at sector and company level, this methodology specifically addresses the challenge of transitory sustainability risks in manufacturing, driven by rapid changes in regulatory frameworks and market expectations, by providing a robust and adaptable framework for comprehensive, bottom-up risk assessment directly on the manufacturing shop floor. Through a detailed literature review, the paper identifies gaps in current risk assessment methods and proposes a novel approach that enhances traditional FMEA by incorporating LCA results, thereby facilitating a comprehensive, quantitative analysis of sustainability risks. The practical application of this methodology is demonstrated through a case study, underscoring its effectiveness in real-world settings and potential for broader applications in sustainable manufacturing. The results presented in the paper also include quantitative sustainability performance benchmarks for the EU28 industrial sector, offering a strategic tool for manufacturers to improve sustainability practices, align operations with environmental standards, and mitigate transitory sustainability risks. This research contributes to the sustainable evolution of manufacturing, providing a methodological foundation for understanding and managing sustainability risks.
In recent years it has become more and more evident that the ability of systems to adapt themselves is an increasingly important requirement. This is not least driven by emerging computing trends like Ubiquitous Computing, Ambient Intelligence, and Cyber Physical Systems, where systems have to react on changing user needs, service/device availability and resource situations. Despite being open and adaptive it is a common requirement for such systems to be trustworthy, whereas traditional assurance techniques for related system properties like safety, reliability and security are not sufficient in this context. We recently developed the Plug&Safe approach for composition time safety assurance in systems of systems. In this position paper we provide an overview on Plug&Safe, elaborate the different facets of trust, and discuss how our approach can be augmented to enable trust assurance in open adaptive systems.
A self-adaptive software system modifies its behavior at runtime in response to changes within the system or in its execution environment. The ful- fillment of the system requirements needs to be guaranteed even in the presence of adverse conditions and adaptations. Thus, a key challenge for self-adaptive software systems is assurance. Traditionally, confidence in the correctness of a system is gained through a variety of activities and processes performed at de- velopment time, such as design analysis and testing. In the presence of self- adaptation, however, some of the assurance tasks may need to be performed at runtime. This need calls for the development of techniques that enable contin- uous assurance throughout the software life cycle. Fundamental to the develop- ment of runtime assurance techniques is research into the use of models at runtime
Connected cars, freely configurable operating rooms, or autonomous harvesting fleets: dynamically emerging open systems of systems will shape a new generation of systems opening up a vast potential for new kinds of applications. In light of the hard-to-predict structure and behavior of such systems, assuring their safety will require some disruptive changes of established safety paradigms. Combining current research results from different disciplines with industrial experience, this paper dares to think out of the box and look beyond the limits of traditional safety assurance. It structures upcoming challenges posed by the emergence of open systems of systems, tries to shift existing paradigms to meet those new challenges, and proposes an abstract conceptual framework building on comprehensive interlinked multi-concern runtime models for dynamically assuring the safety as well as other properties of open systems of systems. As there currently is no comprehensive realization of the framework, we discuss what kind of approaches could fit into which parts of the framework and exemplify this for the case of conditional safety certificates.
Rising automation levels in the automotive domain demand a shift from the fail-safe to the fail-operational paradigm. Fail-operational architectures and behaviors are inherently more complex and thus require special diligence from a safety engineering point of view. In this work, we present how we tailored and applied a methodology that facilitates the design of fail-operational architectures from early design stages on by enabling informed judgment regarding the gradually evolved architecture's fitness for purpose. The method specifically considers resilience regarding dynamic changes in environmental conditions, including V2X aspects and internal capabilities. In this paper, we summarize our experiences in applying the methodology in a highway pilot case study. Furthermore, we present essential extensions of the methodology for modeling and evaluating the operational design domain.
Ad-hoc computer systems can automatically realize higher services when at least two distributed and communicating (embedded) devices come together. For this purpose, they must able to manage appearance and loss of devices and resources, and they have to adapt to changes in requirements and environment. Based on a component-oriented approach for adaptive ad-hoc systems, this paper suggests a high-level service quality reference model to advocate further research on the quality matching problem between service provider and client components.
