Optimum Maintenance Intervals in RCM++. Preventive maintenance can yield significant cost benefits by increasing the availability of a system and reducing the total maintenance costs. The question of how often the task should be performed, however, is important to consider.s weâve seen, given the corrective and preventive maintenance costs and the probability of failure, we can find a time interval that minimizes the total cost function. This task can be performed easily in RCM++ . Figure 6 shows the costs associated with the preventive maintenance.
