Allenthalben hört man immer häufiger, dass in Rechenzentren, dort, wo es richtig zur Sache geht, Linux Rechner in der Hauptsache aufgestellt werden. Das hat sicher mehrere Gründe. Ein wichtiger Grund ist die Lizenzfreiheit der Linux Software. Es macht schon einen deutlichen Unterschied in der Kalkulation, wenn man für Lizenzen 0 Euro einsetzen kann. Dann soll der Linux Server auch bedeutend stabiler laufen. Auch dieser Grund ist nicht von der Hand zu weisen.

Complexity in software systems encompasses numerous interrelated dimensions that are shared by a broad collection of industrial application domains. Examples of complex systems include large-scale enterprise applications supporting the strategic needs of end users, such as supply chain management, customer relationship management, etc. Other examples include sophisticated crisis management systems that must integrate many different and highly autonomous subsystems for efficient handling of potentially life-threatening disaster scenarios, telecoms infrastructure management systems that must automatically configure and re-configure many thousands or millions of customer equipment nodes, world-wide data-centric stream-based systems that have to adapt to sources of data varying in number, volume, format and semantics, upcoming integrated health care systems, and distributed systems that perform safety-critical operations in power grids, air traffic control systems, and industrial automation, and so on. The most critical relevant complexity attributes for all these systems are size, heterogeneity, distribution, dynamicity, and autonomy.
The goal of this Perspectives Workshop is to investigate state-of-the-art techniques available for modelling complex systems, generating code from models or using models as configurations, analysing such models (for verification purposes and for simulation), building languages (e.g., a domain-specific language for worst-case execution time analysis of complex systems), to support the model engineering of complex systems, and linking these modelling techniques to industrial requirements for complex systems development. The seminar will focus on questions of how to decompose, refine and evolve models in such a way that decomposable, refineable and evolvable systems can be developed. Moreover, the support provided by state-of-the-art complex systems modelling techniques for achieving and reasoning about the attributes given earlier will be analysed and summarised, to give a comprehensive overview of how well existing techniques meet these domain requirements, and how much additional research is needed to achieve these goals.
Participants are invited from both the Model Engineering community and the Complex Systems Development community to ensure the conference successfully promotes a shared understanding of complex system domain requirements and state-of-the-art model engineering technologies.
