Abstract
This dissertation is directed at modeling, planning and scheduling MRO (Maintenance, Repair and Overhaul) operations in aviation industry. Tactical level scheduling is designed for a medium-range planning horizon (e.g., two months), which allocates sufficient resources with finite capacity constraints to deal with incoming demand. To achieve this objective, the dissertation problem, defined as tactical MRO scheduling (TMS) problem, is constructed by threefold in order of: resource planning, system state mapping, and their integration for a continuous improvement. Within this infrastructure, being able to explain the relationships between system inputs and outputs, diagnose (nonlinear) linear relationships, predict the necessity inputs for resource planning, and dependently create schedules by means of mathematical optimization is the main objective, as well as the foremast contribution of this dissertation.
