Planned Maintenance Interval (PMI) is a predetermined period of time during which maintenance activities are scheduled to take place. It is a key component of a maintenance program and is used to ensure that equipment and machinery are kept in optimal condition. PMI is typically based on the manufacturer's recommendations, the type of equipment, and the environment in which it is used. PMI activities may include inspections, lubrication, cleaning, and repairs. The goal of PMI is to reduce the risk of equipment failure and extend the life of the equipment. PMI is also known as preventive maintenance, scheduled maintenance, or predictive maintenance.
