A Maintenance Management System (MMS) is a software tool that is used to plan, organize, and track maintenance activities for physical assets, such as buildings, equipment, and machinery. The system is designed to help organizations streamline and optimize their maintenance operations, reduce downtime, and extend the lifespan of their assets. An MMS typically includes features such as work order management, asset tracking, preventive maintenance scheduling, inventory management, and reporting. The system can be used in a variety of industries, including manufacturing, transportation, and facilities management. By using an MMS, organizations can improve their maintenance efficiency, reduce costs, and increase the reliability and availability of their assets.
