| Summary: | Approved for public release; distribution unlimited. === This thesis details an integer programming model to aid in the modernization of the Navy's Maritime Patrol Aviation fleet. Over a user specified time horizon, the model provides a schedule for when to retire, perform avionics upgrades, or transfer current inventory aircraft from the USN to the USNR. Additionally, the model determines when to open a new aircraft production line and the number of aircraft to procure each year. The model optimizes the modernization schedule while taking into consideration required inventory, minimum required percentage of aircraft containing modern avionics, maximum desired mean aircraft age, budgetary limitations, and production line restrictions. The model minimizes the procurement, operating and maintenance costs using the X-System solver.
