Software-intensive systems, in which a considerable fraction of the system development efforts is dedicated to the development of embedded software, are often regarded as the most important software engineering field in the years to come. They are expected to be one key factor of success for many industries such as, for example, the automotive sector, transportation, or medical devices. As today technical systems also become connected to each other using network technology, we no longer only have technical systems which are controlled by isolated operating embedded software. Instead, the software may include complex information processing capabilities and the coordination between the different technical systems via networks taking hard real-time constraints into account.
