Abstract : According to Presidential Policy Directive 21, increasing resilience of critical infrastructures is not only desired, but United States policy. Communications infrastructures are one such critical infrastructure. The purpose of this research is to develop a methodology for measuring resilience in satellite communication systems for use as a key criterion in the selection and acquisition of new satellite architectures, in accordance with the National Security Space Strategy. The base methodology utilized in this thesis is Extreme Event Modeling implemented through the use of Bi-Level Programming with monotonically nonlinear continuous and mixed integer variables. This model differs from previous efforts applied to other critical infrastructures in that it captures the temporal component associated with multiple events, as well as the repairs, or reconstitution, of infrastructure components. Furthermore, a heuristic based upon a ratio of impact to cost and local searches is developed to solve the resulting continuous bi-level problem.
