    Towards flexible and secure end-to-end communication in industry 4.0

    The digital transformation of industrial production is driven by the advance of cyber-physical production systems (CPPS) within which raw materials, machines and operations are interconnected to form a sophisticated network. Making such systems self-adaptable is a priority concern for the future implementation of Industry 4.0 application scenarios. In this position paper, we design a meta-model and use it as a tool to describe an end-to-end communication use case from an ongoing research project. Based on this use case we develop a business process performance and security trade-off model, which shows that maximazing both parameters at the same time is not possible, thus an efficient balance between them has to be achieved. Motivated by the result, we propose self adaptation as a solution towards a flexible and secure end-to-end communication in Industry 4.0. To identify and document the self-adaptation points in a structured methodological and lightweight way we use the bespoken meta-model.

    Project Management in a cultural context
    Theories of project management are well structured guidelines to bring projects to success. Available studies on project success factors stress out that commitment on decisions, reliability and engagement within organizations as well as the benefit for the project sponsor decide over success or failure. In an international context projects face other cultural, technical and economic challenges. For project teams that work together in EU-funded projects the acceptance of cultural differences and the consideration of one´s own and foreign cultural peculiarities form the basis for a successful cooperation. These projects usually produce results for several project sponsors, decisions are made by the coordinator and not directly with the project manager on the partner side. Agile methodologies are simply not possible and project communication is well defined in the project planning phase and alignments are difficult to put through. The authors of this paper stress out that one important project success factor are culture. According to current literature this issue in the context of international project management has potential for further research. With the aim to close this gap a set of selected EU-funded projects are analysed for success factors and problem areas. This paper provides the criteria catalogue of the conducted analysis and a recommended course of action.

    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.
