Research Overview

The research activities of the Real-Time System Lab are centered around the idea of model-driven software engineering. Already finished and still running research projects are organized in 6 clusters shown in the following diagram.

The cluster “Meta-Modeling & Model Transformation” builds the fundament for all other clusters. Based on model engineering technologies and tools developed in this cluster, the “Concurrent Engineering & Tool Integration” as well as the “Model-Based Quality Assurance” clusters represent groups of research projects related to the development of techniques that support synchronization of models across engineering domain on one hand and systematic model-based analysis and testing of software on the other hand. The remaining three clusters “Model-Driven Security Engineering”, “Product Line Engineering”, and “Self-Adaptive Distributed Systems” finally study the application of model-based software engineering concepts from different perspectives with a main focus on high-level specification and generative software engineering techniques. Right now these techniques are mainly used for the development of distributed system monitoring and self-adaptation mechanisms as well as for optimizing software product line quality assurance processes. Studied application domains addressed in cooperations with industry include the model-based development of automation engineering applications, automotive software, etc.

For further details please refer to the more detailed descriptions of these six research clusters. 

Table of Research Topics

eMoflonA tool suite for Model-Driven Engineering (MDE) that provides a range of visual and formal languages for (meta)modelling and model management. eMoflon provides an incremental interpreter for graph patterns and graph transformation rules (for unidirectional model transformation), and for Triple Graph Grammars (TGGs) for bidirectional model transformation.since  2004

The MEMIK approach makes it possible to monitor highly dynamic and structurally complex graph-based models, with the goal to efficiently detect conflicts through the combination of both incremental graph pattern (IGPM) matching and complex event processing (CEP).

MAKIMAKI creates an innovative premise for the communication systems of the future. Its aim is to be more adaptive to changes, particularly during ongoing operations. MAKI considers the diversity of Internet as an opportunity by utilizing the individual attributes of particular mechanisms to meet the desired high quality objectives. ES is active in the sub-projects A1 and A4 of MAKI.since 2013

In this DFG research group, PhD students of different departments improved basic quality aspects of peer-to-peer networks to challenge classical client-server approaches. We investigated external correctness and consistence of data.

As a proof-of-concept a distributed, but nevertheless integrated peer-to-peer-based Integrated Project Support Environment (P2P-IPSE) was developed, which enables a distributed community of users to develop software collaboratively. To achieve interoperability, we improved our ToolNet project, i.e. combine client/server COTS (CASE) tool integration technologies with P2P-based data integration and communication technologies.
