Every system is going to fail and stop operating without asset maintenance management. Maintenance restores the condition of the system back to service when failure occurs. Therefore, the Maintenance plays a significant role in maintaining the availability of system at a specified performance level. With the growth of technology, monitoring some critical parameter has made identification of most suitable time to perform maintenance become possible in the future. Predictive maintenance theory proposed that the change in the performance of a system is the most significant reason to carry out maintenance.
