A computerized maintenance management system (CMMS) is essential for the coordination of all activities related to the availability, productivity, and maintainability of complex systems. Modern computer resources have made it possible to considerably improve the effectiveness and efficiency in the field of maintenance through the use of CMMS. CMMS software solution has evolved from relatively simple mainframe scheduling of maintenance activities to multi-user systems that cover a multitude of maintenance functions. The ability of CMMS to process large amounts of data in a targeted and rapid manner has opened up new possibilities for maintenance, facilitating a more deliberate and thoughtful approach to asset lifecycle management.
