Literature Review: Framework of Prognostic Health Management for Airline Predictive Maintenance

Maintenance plays now a critical role in manufacturing for achieving important cost savings and competitive advantage while preserving product conditions. It suggests moving from conventional maintenance practices to predictive strategy. Owing to the complexity of aircraft systems, Prognostic and Health Management (PHM) provides a set of capabilities that enable diagnostic, prognostic and health management for effective and efficient maintenance. A functional PHM system is required to optimize condition-based maintenance (CBM), mitigate unscheduled maintenance and reduce costs inflicted thereupon. However, a comprehensive review that details previous and on-going efforts in PHM filed is lacking. To fill the gaps, this paper presents the literature review of prognostic health management techniques and the framework of PHM in order to predictive of aircraft maintenance. Moreover, this paper summarizes the challenges in existing research and highlights the opportunities in future research of the PHM framework.
