Reserve P-3 squadrons are directed to maintain a complement of six aircraft in their inventory. This number was determined through the application of a concept known as the crew seat ratio (CSR). While implementation of the CSR provides an accurate means of determining what is required operationally, further application results in excessive aircraft assignments, stressing maintenance capacities. The CSR assumes all aircrew will attain scheduled proficiency and readiness requirements. However, only deploying aircrew are expected to pursue readiness requirements throughout the FRTP. Therefore, applying a consistent ratio to all aircrew results in assigning more aircraft than what is required. The assignment of six aircraft can be burdensome, as reserve maintenance departments are at a disadvantage and not adequately staffed to support that many aircraft. This thesis performs multiple analyses in optimization modeling to determine the minimum (best-fit) number of aircraft assignments for day-to-day operations while maintaining the requisite support for the active duty component. It accounts for constraints resulting from individual training and proficiency requirements, aircrew readiness and qualification requirements, and maintenance practices and capabilities. This thesis examines the development and application of The Orion Model (TOM), and demonstrates feasibility with an optimal solution of four aircraft assigned per squadron.
