An intelligent maintenance system (IMS) is a system that utilizes collected data from machinery in order to predict and prevent potential failures in them. The occurrence of failures in the machinery can be costly and even catastrophic. In order to avoid them, there needs to be a system which analyzes the behaviour of the machine and provides alarms and instructions for preventive maintenance. Analyzing the behaviour of the machines has become possible by means of advanced sensors, data collection systems, data storage/transfer capabilities and data analysis tools. Such as those developed for prognostics. The aggregation of data collection, storage, transformation, analysis and decision making for smart maintenance is called an intelligent maintenance system (IMS).
