Witrynaimperfect maintenance policies is to model the impact of maintenance actions on the system. Most of the imperfect maintenance models lead 45 to the reduction of age or impact the failure intensity, refer to (14; 15; 16). Imperfect maintenance models reducing the degradation level are still a broad field to explore. WitrynaIt is well known that reality is between these two extreme cases: standard maintenance reduces failure intensity but does not leave the system as good as new. This is known as imperfect maintenance. Many imperfect maintenance models have been proposed.
