The objectives of this paper are to provide an overview of the TSAR and TSARINA simulation models, and to illustrate their application. These models were developed to provide a method to assess how airbase attacks would affect the capability of airbases to generate effective combat sorties, and to evaluate how a wide range of airbase improvement options could increase the combat capability of airbases during wartime. TSAR simulates the complex interdependencies between the diverse kinds of support resources needed by a modern military organization to sustain combat, and as such has also been successfully applied to assessments of the readiness and sustainability of other kinds of military organizations. Following a description of model highlights, the application of these models is illustrated with some results from a recent analysis.
