ABSTRACT
In broad terms, maintenance optimization models includes the mathematical models focused on 
finding either the optimal balance between costs and benefits of maintenance or the most 
appropriate time to execute maintenance. Parameters often considered in this optimization are 
the cost of failure, the cost per time unit of downtime, the cost (per time unit) of corrective and 
preventive maintenance and the cost of repairable system replacement. The foundation of any 
maintenance optimization model relies on the underlying deterioration process and failure 
behavior of the component. Over the last decades, maintenance optimization models have 
received growing attention, and by now it is a well-established area of research. This paper 
presents a brief review of existing maintenance optimization models. Several reliable models and 
methods in this area are discussed and future prospects are investigated.
