Defense Logistics Modeling

PAC Core Expertise

AMP, ARM & RASP

The Analysis of Mobility Platform (AMP) is a transportation modeling and simulation framework used to obtain an end-to-end simulation of the Defense Transportation System (DTS) to assist Combatant Command planners, Joint Staff, Office of Secretary of Defense (OSD), United States Army’s Center for Army Analysis (CAA), and USTRANSCOM analysts in refining joint force transportation enabler requirements during Time-Phased Force and Deployment Data (TPFDD) development processes and to provide throughput analysis for airports and seaports.

The Aerial Refueling Model (ARM) is designed to support force structure, acquisition and operational planning studies. Given a Synthetic Theater Operations Research Model (STORM) scenario with receiver mission information, the model creates refueling requests and then produces efficient and feasible tanker schedules to satisfy those requests.

The Replenishment At Sea Planner (RASP) builds and optimizes Combat Logistics Forde (CLF) schedules to sustain Navy ships at sea with fuel, ammunition, and dry cargo. This end-to-end discrete event simulation is used to determine logistics support requirements to operate Carrier Strike Groups, Amphibious Ready Groups, and Surface Action Groups during combat campaign models and simulations.

By integrating this suite of tools, PAC can conduct a full end-to-end simulation of military operational deployments as well as a dynamic simulation of sustainment (fuel, parts, ammunition, etc.) requirements and delivery throughout a campaign. These simulations and our resultant analysis inform force capability and fleet sizing information for the following programs:

Strategic Mobility Air Fleet

The Air Force C-5 and C-17 fleets are managed by USTRANSCOM and provide long distance strategic mobility airlift capabilities for the Department of Defense.

Aerial Refueling Fleet

The Air Force KC-135 and KC-46 fleet are managed by USTRANSCOM and provide worldwide aerial refueling capabilities for the DoD.

Voluntary Intermodal Sealift Agreement

VISA is a partnership between the USG and the maritime industry, administered by the DoT/Maritime Administration (MARAD), to provide DoD with assured access to commercial sealift and intermodal capacity to support the emergency deployment and sustainment of U.S. military forces.

Voluntary Tanker Agreement (VTA) Program

The VTA is an agreement established by MARAD to provide for US commercial tanker owners and operators to voluntarily make their vessels available to satisfy DoD needs.

Civilian Reserve Air Fleet

The CRAF is a voluntary, contract-based agreement between DoD and U.S. commercial air carriers that augments DoD’s military airlift capability during times of war and national emergency.

Tanker Security Program

The FY2021 National Defense Authorization Act (NDAA) required the Secretary of Transportation (SECTRANS), in consultation with the Secretary of Defense (SECDEF), to establish a TSP fleet of active, commercially viable, militarily useful, privately owned product tank vessels to meet national defense and other security requirements.

Surge Sealift

The government-owned or organic fleets include MARAD’s Ready Reserve Force (RRF) and MSC Surge Fleet. The RRF and Surge Fleet support the rapid worldwide deployment of U.S. military forces, primarily the transport of Army and Marine Corps unit equipment, combat support equipment, and initial resupply during the critical surge period before commercial ships can be marshaled.

Maritime Security Program

MSP maintains a modern U.S.-flag fleet providing military access to vessels and vessel capacity, as well as a total global, intermodal transportation network. This network includes vessels, logistics management services, infrastructure, terminals facilities, and U.S. citizen merchant mariners to crew the government owned/controlled and commercial fleets.

Combat Logistics Force

The Navy Military Sealift Command (MSC) operates Fleet Oilers (T-AO) and Dry Cargo and Ammunition Ships (T-AKE) as well as commercially operated cargo and tanker ships. This fleet provides at-sea sustainment to US Navy combatant fleet.
