Sustainment Generator

Sustainment Generator (SUSGEN) is a logistical planning tool that develops records for flow modeling that represent sustainment loads on the transportation system. In other words, it estimates the amount of supplies that deployed forces will consume.

Currently fielded with the US military, SUSGEN can be used in crisis actions to “block” lift until the supply requisition systems activate. Sustainment is based on the incremental population expansion of the theater, and is produced for all military classes and sub-classes of supply.

SUSGEN is dependent on a Logistics Factors File (LFF), which is available on the Global Command and Control System (GCCS). SUSGEN supports CFAST plan building and JFAST transportation planning. SUSGEN is used in the planning process one may follow to define logistics planning factors for a Time-Phased Force and Deployment Data (TPFDD) deployment plan and to generate non-unit sustainment movement requirements to add to the TPFDD in CFAST.

Estimates of the arrival of sustainment tonnage can be obtained by modeling sustainment requirements in transportation flow models created by JFAST. The TPFDD records that SUSGEN generates enable USTRANSCOM to see a total picture of the movement of forces and sustainment, allowing a determination of overall transportation feasibility.
