One of the most important costs occurring in the production process are Maintenance Costs. Huge investments are required to replace the parts, check the electric parts and machining parts, etc. to minimize the downtime of the production line.
But when should we replace any used part? Every month? Every year? If we were talking about a car, we could predict the tires or plug wires, should be changed after a definite millage. But in a production line in a factory we cannot easily set up such schedules.

Maintenance Operation is divided to: Reactive (Too Late) and Proactive.
Proactive Maintenance is also two types: Preventive (Too Early) & Predictive (Right One).
In Predictive Maintenance, we use the right Life Span of machine parts through Real Time Sensing of parts behaviors.
By this method only, we will be able to reduce the costs curve to a minimum.
