An optimization model for sea-based supply of bulk fuel for a deployed marine expeditionary unit

Abstract

Operational Maneuver From the Sea (OMFTS) is a Marine Corps concept that shifts the emphasis from blue-water superiority to power projection in the littorals. OMFTS treats the sea as maneuver space, and moves forces directly from ship to objectives ashore with little or no prior build-up of supplies ashore. This thesis develops the Sea-Based Logistic Optimization Model (SBLOM), an integer programming model that assesses the feasibility of conducting sea- based logistics in an OMFTS scenario based on capabilities of current and future assets, e.g., the Landing Craft Air Cushion and the MV-22 Osprey aircraft. SBLOM minimizes (when feasible) the initial fuel requirement of the Marine Expeditionary Unit (Special Operations Capable) (MEU(SOC)) ashore, and develops a fuel-delivery schedule from the sea using the lift assets available on a group of three or four ships known as an Amphibious Readiness Group (ARG). Using two OMFTS scenarios, SBLOM is run with the ARG at stand-off distances of 50, 70, and 100 nautical miles. The scenarios involve a humanitarian mission and an amphibious raid. In all cases, the use of sea-based logistics is feasible: An optimal delivery schedule is developed that meets the daily fuel requirements of the MEU(SOC) and maintains sufficient fuel levels the throughout the mission's duration.
