SOFIA

Interdependent Infrastructure Modeling, Simulation, and Analysis Project (SOFIA)

Critical infrastructure protection is a recognized problem of national importance. Infrastructure interdependence research and applications require a seamless and unified view of infrastructure as a "system of systems," but existing infrastructure modeling efforts, however, have been hampered by an inflexible software technology base. The Simulation Object Framework for Infrastructure Analysis (SOFIA) project at Los Alamos National Laboratory aims to research and develop a high-quality, flexible, and extensible actor-based software framework for the modeling, simulation, and analysis of interdependent infrastructures. At the end of its three-year duration, we intend to have a state-of-the-art tool for the analysis of interdependent infrastructures and to have applied it to innovative research questions of national importance. This integrated, holistic, event-based approach handles multiple problem domains, varying levels of component aggregation, disparate time scales, heterogeneous simulation algorithms, sensitivity to uncertainties, and data visualization to study issues related to the characterization of infrastructure system complexity, sensitivity, robustness, and degree of interdependence, and to the identification of critical components, synergistic behavior, and fundamental limits on the predictability of these systems. Present work in SOFIA focuses on the simulation of interconnected electric power and natural gas infrastructure, along with their associated control systems.
