Federated simulations for systems of systems integration

Systems of systems integration is a difficult engineering challenge that places a particular burden on the engineers who must develop simulation models to support that in-tegration. Developing a large scale stand-alone model to support systems integration is a time-consuming process that is often not possible. An alternative approach is to leverage existing models in a federation. This type of work requires a specialized set of engineering skills. The United States Military Academy Department of Systems Engineer-ing SysHub research program is better defining these skills and applying them to different problem domains. This pa-per highlights how capabilities for information exchange, environmental representation, entity representation, model development, and data collection support the federation development process.
