Complex software systems have to follow constantly changing requirements. Their dependability and reliability has to be maintained over long periods. In practice, software changes often lead to a decline of quality characteristics such as maintainability, flexibility, clarity, reliability and efficiency. Incomplete and inadequate changes lead to damages of the structure. Such effects are also known as architectural decay or entropy loss. A close linkage between forward and reverse engineering methods and techniques, and an enforced use of models should help to avoid such effects. By maintaining the evolvability of the software systems, a permanent further development can be achieved. Furthermore, the methods enable an improved tool support and an increased efficiency of the software development.
The evolutionary development of software systems requires models as the basis for the development activities. Linking the models of requirements, architectures and implementation are particularly essential to solve complex tasks. Traceability links have proved to be an important means to maintain the consistency of the models of different views, which are necessary to manage the complexity. The descriptions used must be based on a sound basis, and they have to be supported by adequate development methods. The bridging of the transition between requirements specification and architectural models which is often referred to as a semantic gap, demands for special methods and models, as well as for an explicit representation of traceability links and dependency relationships.
The research of the group is focussed on applications in the domains of embedded systems, especially for automotive and telecommunication systems, for logistics and for data-intensive applications.
