Abstract

A method for optimizing the availability of a technical object, comprises the steps of providing a serviceable technical object; defining a service plan; defining a setpoint availability; maintaining the serviceable technical object according to the service plan; determining the actual availability of the serviceable technical object; and automatically adjusting the service plan according to a difference between the setpoint availability and the actual availability.

Claims

1. A method for optimizing the availability of a technical object comprising the steps of:

providing a serviceable technical object;

defining a service plan;

defining a setpoint availability;

maintaining the serviceable technical object according to the service plan;

determining the actual availability of the serviceable technical object;

automatically adjusting the service plan according to a difference between the setpoint availability and the actual availability.

2. The method according to claim 1, wherein the step of determining the actual availability of the serviceable technical object is performed manually by a service personnel.

3. The method according to claim 1, wherein the step of determining the actual availability of the serviceable technical object is performed automatically by evaluating at least one sensor value which determines a parameter of the serviceable technical object.

4. The method according to claim 1, wherein the service plan includes a maintenance schedule including at least one service interval.

5. The method according to claim 1, wherein the service plan includes a task list.

6. The method according to claim 4, wherein the step of adjusting the service plan includes the step of increasing or decreasing said service interval.

7. The method according to claim 5, wherein the step of adjusting the service plan includes the step of adding or modifying a task.

8. The method according to claim 1, wherein said method steps are performed for a plurality of serviceable technical objects with a plurality of setpoint availabilities for each object and a plurality of actual availabilities for each object, and wherein the method comprises the steps of:

determining a resulting availability from said plurality of actual availabilities; and

adjusting each service plan according to each actual availability and according to said resulting availability.

9. The method according to claim 8, wherein each serviceable technical object is of the same or similar type.

10. The method according to claim 1, further comprising the step of providing a cost analysis for providing said availability.

11. A system for optimizing the availability of a technical object comprising:

a serviceable technical object;

means for defining a service plan;

means for defining a setpoint availability;

means for maintaining the serviceable technical object according to the service plan;

means for determining the actual availability of the serviceable technical object;

means for automatically adjusting the service plan according to a difference between the setpoint availability and the actual availability.

12. The system according to claim 11, wherein a service personnel determines the actual availability of the serviceable technical object.

13. The system according to claim 11, comprising at least one sensor value for determining a parameter of the serviceable technical object which relates to the availability of said object.

14. The system according to claim 11, wherein the service plan includes a maintenance schedule including at least one service interval.

15. The system according to claim 11, wherein the service plan includes a task list.

16. The system according to claim 14, wherein the means for adjusting the service plan increase or decrease said service interval.

17. The system according to claim 15, wherein the means for adjusting the service plan add or modify a task of said task list.

18. The system according to claim 11, comprising a plurality of serviceable technical objects with a plurality of setpoint availabilities for each object and a plurality of actual availabilities for each object, and further comprising:

means for determining a resulting availability from said plurality of actual availabilities, wherein each service plan is adjusted according to each actual availability and according to said resulting availability.

19. The system according to claim 18, wherein each serviceable technical object is of the same or similar type.

20. The method according to claim 11, further comprising means for providing a cost analysis for providing said availability.

21. A method for optimizing the availability of a technical system including a plurality of serviceable technical objects, comprising the steps of:

defining a service plan for each serviceable technical object;

defining a setpoint availability for each serviceable technical object;

maintaining each serviceable technical object according to each service plan;

determining each actual availability of each serviceable technical object;

determining a resulting availability from all determined actual availabilities; and

automatically adjusting the service plan according to a difference between the setpoint availability and the actual availability and according to said resulting availability.

22. The method according to claim 21, wherein each service plan includes a maintenance schedule including at least one service interval.

23. The method according to claim 21, wherein the service plan includes a task list.

24. The method according to claim 22, wherein the step of adjusting the service plan includes the step of increasing or decreasing said service interval.

25. The method according to claim 23, wherein the step of adjusting the service plan includes the step of adding or modifying a task.

26. The method according to claim 21, wherein each serviceable technical object is of the same or similar type.

27. The method according to claim 21, further comprising the step of providing a cost analysis for providing said availability.
