<p>The United States Navy's Military Sealift Command (MSC) employs its Combat Logistics Force (CLF) to supply the combatant fleet through replenishments at sea (RAS). These RAS events need to be conducted where the combatant fleet operates. In order to give logistics planners an accurate view of RAS locations, we create heat maps from historical RAS evolutions to illustrate and calculate the most probable location for future events. We compare relying on this estimated location with current practice of using the corresponding center point of a given Operational Area Box (OP Box) and determine the impact of this centroid location on CLF assets, fuel cost, and time. The Pacific Coast scenario that we present uses the Replenishment at-Sea Planner (RASP) to find the optimal scheduling of RAS events at both the OP Box center point and the estimated RAS location. The results show that the centroid location offers significant improvements in customer readiness and total CLF underway fuel usage planning.
