Abstract:
|
Historical reliability data provide crucial information about aircraft maintenance and have presented many challenges for reliability data analysis. Irregular types of cutoffs and bounds as well as latent and evident features of the lifetimes, superimposition of lifetime processes, and unobservable degradation paths have troubled the ways industry do aircraft maintenance and inventory replenishment planning. In this talk, we show that advanced reliability methods have been developed and implemented to design a maintenance process as a continuous analysis and process system based on performance values experienced for model-specific fleets flown by multiple operators under a variety of operating conditions and environments. We provide an overview of the maintenance tools in which statistical reliability methods were used to support the maintenance optimization processes.
