Towards continuous evolution through automatic detection and correction of service incompatibilities

Systems with long life times need to continuously evolve after deployment in response to changing technology and business needs. Lacking this ability not only prevents systems from quickly reacting to these changes, but also increases risk, as many small updates are collected into big infrequent upgrades. Service-oriented architectures support...

A digital twin method for automated behavior analysis of large-scale distributed IoT Systems

Reducing Design Time and Promoting Evolvability using Domain-specific Languages in an Industrial Context

The complexity of cyber-physical systems is increasing, driven by integration of more functionality and trends towards mass-customization. This has resulted in complex systems with many variants that require long time to develop and are difficult to adapt to changing requirements and introduction of new technology. New methodologies are hence...

Virtual Prototyping of Large-Scale IoT Control Systems Using Domain-Specific Languages

IoT applications and other distributed control applications are characterized by the interaction of many hardware and software components. The inherent complexity of the distributed functionality introduces challenges on the detection and correction of issues related to functionality or performance, which are only possible to do after system...

Using Digital Twins to Create and Manage Complex Distributed Control Systems

Building Distributed Co-simulations using CoHLA

The construction of a co-simulation for large cyberphysical systems can be very time consuming. We have defined a domain specific language called CoHLA that facilitates this construction based on the standards FMI and HLA. Scalability of this approach is investigated by the application to Internet of Things (IoT) systems. Because of the...
