Development and the deployment of COSAGE 2.0

The COmbat SAmple GEnerator (COSAGE) model is a stochastic, symmetric, two-sided combat simulation model implemented in SIMSCRIPT II.5. This model is primary used as a calibration for Attrition Calibration (ATCAL) base theater-level models including the Joint Integrated Contingency Model (JICM), Synthetic Theater Operations Research Model (STORM) (AF, follow-on to Thunder), and Integrated Theater Engagement Model (ITEM) (Navy). In 2009 it was determined that CAA would re-write the model in C++ in order to improve the modularity, ability to enhance the methodology and model maintenance. This paper focuses on the entire development process of the new model from the decision to re-write the model to the testing and evaluation prior to model deployment.
