Modeling and Simulation of Systems of Systems
ABSTRACT
The trend toward modeling and simulation-based acquisition of systems-of-systems in defense and other domains is accelerating. For example, the Ballistic Missile Defense System (BMDS) needs such technology not only to support acquisition, but also to synchronize sustained acquisitions of its component systems. The BMDS typifies a system of systems for which thorough, system-level, live testing is unaffordable, impractical, unsafe or illegal. Thus, BMDS acquisition relies increasingly on M&S to estimate performance of current and future architectures against adversary threats. The complexity of such tasks is creating a need for automatic selection, construction, and testing of end-to-end scenarios based on suites of models covering the conceivable component models and alternatives compositions. In this talk, we describe how we are developing an environment to support selection of components and couplings to compose system models best able to meet the on-demand intended use and objectives of stakeholder users. We first overview the Modeling and Simulation Framework and generative ontology of the System Entity Structure on which the environment depends. Then we show how the framework’s fundamental origin in dynamic systems theory and the Discrete Event System Specification (DEVS) formalism are necessary to meet the complexities of modeling and simulation of defense and other systems of systems. Finally we show how such a capability can grow and evolve with stakeholder needs over the long term.
