WitrynaTwo PM types are performed, i.e. imperfect PM and perfect PM. The likelihood that PM is perfect depends on the number of imperfect maintenance activities have been performed since the last renewal cycle. Mathematical formulae for expected cost per unit time are developed. The optimal period for periodic PM, which minimizes cost, is … Witryna1 lis 2024 · Panday et al. (2013) also studied the selective maintenance problem for binary systems under imperfect maintenance. The hybrid hazard rate approach introduced in Lin et al. (2000) is used to model the imperfect PM actions. Accordingly, both age reduction coefficient and adjustment coefficient impact the component health.
