Airline Fleet Rotables Staggered Replacement Scheduling using Dynamic Approach

The purpose of this paper is to describe the application of a dynamic approach for scheduling of airline rotable components preventive maintenance in order to minimize earliness costs and maximize on wing time of the components. First, analysis of required service level is performed to determine minimum stock quantity for unscheduled replacements, or removals for repair. Then, a schedule for staggered replacement of propeller blades and hubs for overhaul on a regional turbo-prop aircraft fleet is given, with limited availability of spare blades and other constraints. Results show that a minimal cost solution without part shortages can be obtained.
