Maintenance refers to the processes and activities involved in keeping equipment, machinery, and facilities in good working condition. This includes regular inspections, repairs, and replacements to prevent breakdowns and ensure safety. Effective maintenance can extend the lifespan of assets and improve operational efficiency. There are various types of maintenance, such as Preventive Maintenance, which aims to prevent issues before they occur, and Predictive Maintenance, which uses data analysis to predict when maintenance should be performed. By implementing a robust maintenance strategy, organizations can minimize downtime and reduce costs associated with unexpected failures.
