About

The SmartArch research group is a part of the Department of Distributed and Dependable Systems, Faculty of Mathematics and Physics, Charles University in Prague, Czech Republic. SmartArch focuses on dynamic software architectures for modern smart systems. This comprises modern IoT system, smart cyber-physical systems (CPS), cloud, and edge-cloud systems.

We focus on state-of-the-art methods of model-driven development, requirements-oriented design, and component-based modeling and development. We specifically target large-scale software-intensive cyber-physical systems and aim at developing holistic, multi-paradigm, and well-integrated methods for modeling and developing such systems. Further, we focus on interconnection with cloud and especially edge-cloud and data processing that has soft real-time and other QoS requirements.

Our Research

We build on our long standing experience with design and development of component models. Starting from the SOFA 2 component model, we collaborated on the ProCom component model for real-time embedded devices and capitalized the experience with these models in the novel component model DEECo, which was conceived within project ASCENS (FP7, FET) for modeling and development highly distributed and dynamically evolving decentralized smart cyber-physical systems. In DEECo, systems are modeled as ensembles of opportunistically cooperating autonomic components.

These results of the ASCENS project established a new branch of component models, so called ensemble-based component models. We have continued in this line with the design methods (namely the Invariant Refinement Method – IRM), many testbeds (robots, autonomous vehicles, adaptive edge- and ad-hoc cloud, coordination in rescue scenarios), and further models, domain-specific languages and frameworks for development of ensemble-based systems.
