Imperfect maintenance … Witryna1 sie 1990 · Two types of preventive maintenance policies are considered. A policy is defined to be optimum if it maximizes “limiting efficiency,” i.e., fractional amount of up-time over long intervals. Elementary renewal theory is used to obtain optimum policies.
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. WitrynaAmong the categories, imperfect maintenance is the most realistic one since it restores the equipment to the state between as good as new and as bad as old. Many studies …
