In order to take a step forward to practice, the system is assumed operating under indirect condition monitoring. The degradation of system is described by a crack growth evolution modelled by the Paris-Ergodan law, and a non-destructive ultrasonic technique is used to monitor the system condition. A procedure of state estimation and prediction of values associated with system health from the noisy measured data are performed thanks to the well-known particle filter algorithm. Then based on these estimated/predicted value, a dynamic maintenance policy is developed and is compared with two more classical policies (i.e. block replacement or periodic inspection/replacement). The comparison results on the optimal expected maintenance cost rate will show the performance of the proposed dynamic maintenance. %G English %L hal-02558062 %U https://utt.hal.science/hal-02558062 %~ CNRS %~ UNIV-TROYES %~ UTT %~ UTT-LIST3N %~ LM2S-UTT
