ABSTRACT (maximum 200 words) Military Sealift Command (MSC) introduced its new Dry Cargo and Ammunition Ship (T-AKE) in June 2006, to replace its retiring ammunition and fast combat stores supply ships. MSC seeks new ways to use T-AKEs, fleet replenishment oilers, and fast combat support ships to better support the U.S. Navy. We evaluate two alternate ways to manage these ships, one where each ship operates under a particular “fleet ownership,” and another where these ships are “globally allocated,” serving any fleet customer as needed worldwide. We introduce an optimization-based scheduling tool, and use it to evaluate an expository 181-day peacetime scenario. We track daily inventories of 13 battle groups --- carrier strike groups, expeditionary strike groups, surface strike groups, and a littoral combat ship squadron --- to gain insight into how to best employ CLF ships. We determine that, in our scenario, global allocation provides significantly better service to fleet customers. 14.
