In condition-based maintenance area, mean residual life function is recognized as a promising reliability indicator for maintenance decision-making. However, very few maintenance strategies based on the mean residual life have been developed. This paper therefore analyzes a predictive maintenance strategy based on the mean residual life given the degradation level collected periodically in different inspection times. This strategy is developed for systems which are subject to competing and dependent failures due to degradation and traumatic shocks. Numerical examples are given to illustrate the analytical results of the strategy.
