Prognostics and Health Management (PHM) System
摘要
Maintenance in shipping today follows either a reactive maintenance (RM) or preventive maintenance (PM) approach [261]. RM introduces high risks of unscheduled downtime, while PM provides relatively high reliability, but at unnecessary costs due to predetermined maintenance intervals. PM also will not detect random failures which are in fact the most common failure pattern in the maritime industry. Thus, a more predictive maintenance approach is necessary to identify these kinds of failures. A predictive system will significantly increase operating performance and drastically decrease unexpected system failures [262].
