Competence Centre Model-Based Development

The increasing complexity of software requires specific models with varying degrees of abstraction to ensure the efficient development of high-quality systems. These models are specifically tuned towards different views on the system under development, dependent of the different phases of the development process.

The framework developed by the competence centre consists of the following layers of abstraction:

Functional Architecture: Models of the functional architecture describe the functionalities offered by the system (from the application point of view), including their relations. The functional architecture focuses on the description of those functions independent of their implementation.
Logical Architecture: Models of the logical architecture describe how the system is structured into logical components cooperating by communication: the component hierarchy is defined independent of the technical platform.
Technical Architecture: Models of the platform describe the available resources for the implementation of the system under development, i.e. the available sensors and actors, processing units, and communication paths.

The current field of research of the competence centre is the integrated model-based development. For this purpose, we have been investigating the relations between different layers of abstraction, e.g., the mapping of functions to components or components to resources, and defining them formally. This leads to increased process efficiency by a higher degree of automation as well as increased product quality by eliminating defects introduced by manual development steps.
