Forces Planning Model - FPM

Joint Chiefs of Staff, Force Structure (J-8); Washington, DC

FPM is an integrated, global model designed to assess the impact of budget and force structure changes. Investment, development, and operations and support costs are computed for DoD and the Services. Effectiveness modeling considers unit weapon system characteristics when determining and calculating force ratios and attrition.

The model works with joint and combined forces, BLUE and RED. It handles conflict escalation from conventional warfare to chemical warfare, non-strategic warfare, and strategic nuclear warfare. The model considers lift mobility, and sustainability. It includes ground combat, air combat, ground-vs.-air combat, interdiction, airbase attack, SAM suppression, close air support, escort, battlefield, and airbase defense.

Inputs to the model include appropriate budget, force structure, system characteristics, and scenario data. Inputs are highly aggregated to facilitate fast operation. Calculations are made using cost factors that are loaded into the Cost Module (CM) from the cost database or made dynamically within the CM from information passed from the Integration Module (IM). Components of the Effectiveness Module (EM) have been extensively linked together in a dynamic structure to emphasize the interaction among ground, air, and naval forces as well as mobilization and lift capabilities.

The IM primarily produces intermediate data files, which are read by the CM and the EM. CM outputs include a variety of output files describing the costs of base case and revised force structure. EM output contains different levels of detail, a variety of measures of effectiveness for all theaters for all cycles for a broad overview to more detailed information on a cycle-by-cycle basis.
