What type of maintenance involves replacing parts based on a predetermined schedule?

Preventive maintenance is focused on performing maintenance tasks at regular intervals according to a predetermined schedule, irrespective of the current condition of the equipment. This approach aims to prevent equipment failures and extend the lifespan of machinery by regularly checking and replacing components, lubricating moving parts, and making adjustments as needed.

The primary goal of preventive maintenance is to minimize unplanned downtime and enhance operational efficiency by anticipating maintenance needs before issues arise. By adhering to a set schedule, organizations can ensure that their assets remain in optimal working condition. This practice not only helps in reducing the chances of unexpected breakdowns but also aids in budgeting and planning for maintenance activities.

In contrast, options that involve waiting for equipment to fail before addressing issues, such as reactive maintenance, do not align with the principles of preventive maintenance. Predictive maintenance employs data-driven techniques to predict when maintenance should be performed, and prescriptive maintenance goes a step further by recommending specific actions based on the analysis of data, making preventive maintenance the most straightforward method for scheduled part replacement.
