ABSTRACT
Related to CMT modeling, Scarf (1997) determined that no model was designed for modeling the deterioration level of a component beyond which preventive activities had to be applied. Since that affirmation, a small number of papers have been developed dealing with this subject. Barata et al. (2002) determine a CMT model to find the optimal degradation thresholds of maintenance intervention, dealing with corrective replacement, preventive replacement and PM costs. Marseguerra et al. (2002) study a continuously monitored multi-component system that models the profit obtained from system operation, maintenance costs and penalties during downtime, for determining the optimal degradation level beyond which PM has to be performed. Liao et al. (2005) present a CMT model for continuously degrading systems to determine the optimum maintenance threshold based on inspection, maintenance, failure and replacement and maximize system availability.
