Modeling and Simulation of Systems of Systems

Course Length:



This three-day course is de¬signed for engineers and managers who wish to enhance their capabilities to construct, work with, and/or understand state-of-the-art concepts and tools for modeling and simulation for systems of systems. The course covers the basics of systems concepts and discrete event systems specification (DEVS), a computational basis for system theory. It demonstrates the application of DEVS to “virtual build and test” of engineered systems of systems, the increasingly adopted alternative to complex systems development. Discussion of DEVS-Compliant; environments will provide examples of state-of-the-art agent-based, high-fidelity SoS space-systems simulations. Students will gain access to modeling and simulation software that provides hands on experience with integrated development and testing of modern component-based systems.

What you will learn:

  • Basic concepts of Discrete Event System Specification (DEVS) and how to apply them using simulation software
  • How to understand and simulate systems with both Discrete and Continuous temporal behaviors
  • System of Systems Concepts, Interoperability and service orientation, within a modeling and simulation framework
  • Integrated System Development and Testing with applications to service oriented architectures
  • Concepts and Tools at the cutting edge of the state-of-the-art exemplified by advanced adaptive complex systems environments.

From this course you will obtain the understanding of how to leverage collaborative modeling and simulation to analyze systems of systems problems within an integrated development and testing process.
