Abstract: | This paper investigates the optimal threshold values of age to perform preventive maintenance (PM) actions for leased equipment
within the lease period. In this paper, we use age reduction method to describe the degree of PM and construct the maintenance
cost function. For repairable leased equipment, two maintenance models are proposed: (i) maintenance policy of single-phase
and (ii) maintenance policy of two-phase. During the lease period, PM actions are carried out when the age of equipment reaches
a certain threshold value. Any failure of the leased equipment is rectified by a minimal repair within the lease period. Under
these maintenance schemes, the mathematical models of the expected total cost for maintenance policies of single-phase and
two-phase are established, and the optimal maintenance policies are derived such that the expected total cost is minimized.
Finally, the features of the optimal maintenance policy are illustrated through numerical examples. |
