International competition, shorter product life cycles and faster technological leaps forward – these are only a few of the challenges the production of a company is facing in the 21st century. In order to survive in an environment like this, resource-efficient and secure planning of production processes are necessary to guarantee a consistent and high quality output. Unforeseeable machine failures as well as performance drops or deterioration in quality because of defective system components can lead to shortness of supplies which will eventually weaken the market position of the entire organization.
To meet these requirements organizations are increasingly focusing on the improvement of maintenance, repair and operations of their machinery. In the previous years, the industry shifted their focus away from only reactive repair mechanisms towards the predictive coordination of machine maintenance.
Predictive Maintenance falls under the category of the future of maintenance developments. Originally developed in the course of the “Industrie 4.0” high-tech strategy of the German government, today Predictive Maintenance represents the informatization of production processes - intelligent IT-based production systems on the path towards a Smart Factory. Through the generation and analysis of different machine data, the predictive power of the state of industrial plants is not only enhanced, but also provides the basis for an improved planning certainty as well as the efficient planning of repair and maintenance work.

6. The requirements on maintenance
International competition
Shorter product life cycles
Faster technological leaps
More complex business processes
Shift from product to service
7. Evolution of Maintenance Concepts
Reactive or Breakdown Maintenance
Preventive or Periodic Maintenance
Condition-based Maintenance
Unplanned production shutdowns
Inefficient use of resources
Simple rules
Not very precise
8. Predictive Maintenance as an extension of condition-based maintenance represents the informatization of production processes. With intelligent IT-based production systems Predictive Maintenance represents one important step on the path towards the development of a Smart Factory in industrial production.

Example – Gearbox Bearing damage in wind farm
•Reactive Maintenance
•Cost for a replacement of the bearing $ 250.000
•Cran costs $ 150.000
•Power generation / Revenue losses $ 26.000
$ 426.000

10. Predictive Maintenance
Example – Gearbox Bearing damage in wind farm
•Predictive Maintenance
Use of acceleration sensors, oil particle counters and weather forecast modules, plus reliable evaluation of the data
Early detection of the damage at the gearbox bearing
•Repair instead of exchange of the bearing $ 30.000 < $ 250.000
•Lower cran costs $ 75.000 < $ 150.000
•Power generation / Revenue losses $ 2.000 < $ 26.000
$ 107.000 < $ 426.000
