A competing risk model for dependent and imperfect condition–based preventive and corrective maintenances

Abstract: This article develops a model for dependent and imperfect condition-based preventive and corrective maintenance actions. The approach is based on the combination of the intensity proportional repair alert, a competing risks-based model and the generalized renewal process. Typically, intensity proportional repair alert can identify either how preventive actions may modify the distribution of the time between critical failures or how corrective events may change the frequency of preventive maintenances, but this… Show more

“…As, in the cases of deteriorating(improving) systems, the hazard function is directly(inversely) proportional to the age, the better the interventions the lesser(greater) the virtual age, always decreasing hazard characteristics underlying the system. Several examples in literature, such as [ 2 5 ], and [ 6 ] make use of this reasoning.…”

“…Authors like [ 2 , 3 ], and [ 7 ] have resorted to the Weibull-based GRP (WGRP). In these cases, the parameters set of the WGRP is thus ( α , β , q ), representing, in this order, the scale, shape, and virtual age parameters.…”

“…Much research that concentrates on optimizing the control limits and/or inspection intervals of CBM have been done. [4][5][6][7][8] On the one hand, unlike TBM that determines maintenance activities based on a probabilistic model of system failure, CBM makes maintenance decision based on the real-time condition of the system, which is more accurate. On the other hand, due to the development of sensor technology, the degradation behavior of the system can be easily monitored to predict failure events.…”
