    Supply Chain Management in a Circular Economy
    (Leykam, 2019)
    Since Supply Chain Management became a management discipline in the early 1980s the topic was seen in a process-oriented view – structured, well designed and manageable. This process-oriented view was supported by the world ́s linear view- point on rules within our economy, in short-terms take-make-waste. Megatrends and sustainable ecological thinking allow a new way of process design to a so-called Circular Economy where someone ́s waste is someone else ́s food. Processes within a Circular Economy aim in building new ways of production, usage and recycling of materials and thus create new business models. This research provides a guideline on how to design a supply chain within a Circular Economy.

    Towards trustworthy end-to-end communication in industry 4.0

    Industry 4.0 considers integration of IT and control systems with physical objects, software, sensors and connectivity in order to optimize manufacturing processes. It provides advanced functionalities in control and communication for an infrastructure that handles multiple tasks in various locations automatically. Automatic actions require information from trustworthy sources. Thus, this work is focused on how to ensure trustworthy communication from the edge devices to the backend infrastructure. We derive a meta-model based on RAMI 4.0, which is used to describe an end-to-end communication use case for an Industry 4.0 application scenario and to identify dependabilities in case of security challenges. Furthermore, we evaluate secure messaging protocols and the integration of Trusted Platform Module (TPM) as a root of trust for dataexchange. We define a set of representative measurable indicator points based on existing standards and use them for automated dependability detection within the whole system.
