AI-Assisted Optimization of Schedules
Air Force flight and training scheduling is a labor-intensive and largely manual process. Complex training requirements and dependencies, operational constraints, numerous qualifications, and unforeseen missions confound the schedule development process. In this project, we develop deterministic and robust optimization formulations for the Air Force training scheduling problem. We account for the propagation of disruptions, incorporate user preferences, and identify metrics and objective functions to compare candidate schedules.
