The total maintenance cost curve typically starts high due to initial breakdown and repair costs. As preventive maintenance increases, these costs decrease because the equipment is better maintained, leading to fewer breakdowns. However, after a certain point, the cost of preventive maintenance itself can become excessive, causing the total cost to rise again. This reflects the diminishing returns of overly frequent preventive maintenance.
