With respect with a permanent decreasing innovation cycles of increasingly complex distributed systems, and regarding their efficient operation and maintenance, application of quantitative models and simulations is of growing importance

  • for systems design and development,
  • for configuration planning, and operation and maintenance management and
  • for training and education.

Effective model and simulation applications require adaptability and reusability of models and submodels. Therefore, conceptual and methodological approaches for modular, component-based model construction (as opposed to complex monolithic models), and adaptation of model components – based on solid theoretical foundations – is urgently required. The lack of system theoretic foundations for component-based modeling and simulation, and missing international standards, as well, currently results in the implementation of proprietary models, model „components“ and „component“ interfaces, allowing only limited interoperability and reusability of those modules.

Regarding the above mentioned trends and requirements major topics of this Dagstuhl-Seminar will focus on:

  • System theoretic definitions and foundations for model-components (especially regarding differences to definitions and specifications of software-components),
  • Specification of model components (and interfaces),
  • Hierarchical, component-based model development regarding cost-benefit, quality, performance, reliability, and reusability aspects,
  • Architectures for component-based model and simulation applications,
  • Verification and validation methods for model components,
  • Synergies for the application of software-component-technologies in their application for building model-components.


In the series Dagstuhl Reports each Dagstuhl Seminar and Dagstuhl Perspectives Workshop is documented. The seminar organizers, in cooperation with the collector, prepare a report that includes contributions from the participants' talks together with a summary of the seminar.

Dagstuhl's Impact

Please inform us when a publication was published as a result from your seminar. These publications are listed in the category Dagstuhl's Impact and are presented on a special shelf on the ground floor of the library.


Furthermore, a comprehensive peer-reviewed collection of research papers can be published in the series Dagstuhl Follow-Ups.
