The Fast Theater Model (FATHM)
Brown, Gerald G.
MetadataShow full item record
The Fast Theater Model (FATHM) is an aggregated joint theater combat model that fuses Air Force Air-to-Found attack sortie optimization with Ground-to-Gound deterministic Lanchester fire-exchange battles using attrition rates derived from the Army's COSAGE model. The modeled FATHM war is conducted in short periods, with Air-to-Ground and Ground-to-Ground actions carried out in parallel. Period-by-period, damaged and destroyed targets may regenerate, and there may be scheduled reinforcements of attacking platforms, munitions, and new targets. The war progresses in phase whose completion depends on threshold levels of target kills in class categories and limits on phase duration. Each phase has a separate COSAGE input file, so the phases may differ strongly from each other. All FATHM inputs and outputs are ASCII flat-files suitable for immediate integration with a host database and spreadsheet analysis. Completion of a full-scale theater scenario requires about ten minutes on a personal computer.
