Abstract

A reliability centered maintenance system having an input device and logic that receives and stores data indicative of a function, a functional failure, a failure mode, and a failure effect, via the input device, displays the received data to a display device in response to a first user input, and displays a plurality of logical selectable input boxes corresponding to a type of the failure mode and at least one task or default strategy for addressing the failure mode. The logic further receives at least one selection input via the selectable input boxes and receive data describing the at least one task or the at least one default strategy.

4. The system of claim 1, wherein the plurality of selectable input boxes comprises a portion of boxes for indicating hidden failure modes.

5. The system of claim 4, wherein the portion of selectable input boxes comprises a box configured for indicating an on-condition task, a restoration task, a replacement task, an operational check, or a combination of tasks associated with the failure mode.

6. The system of claim 1, wherein the plurality of selection input boxes comprises a portion of boxes for indicating evident failure modes.

7. The system of claim 6, wherein the portion of selectable input boxes comprises a box configured for indicating an on-condition task, a restoration task, a replacement task, an operational check, or a combination of tasks associated with the failure mode.

8. The system of claim 1, wherein the logic is further configured to receive, via the input device, data indicative of a time interval associated with performing the at least one task.

9. The system of claim 8, wherein the logic is further configured to receive, via the input device, data indicative of a maintenance package corresponding to the time interval.

10. The system of claim 9, wherein the logic is configured to generate a report comprising data indicative of the at least one task or default strategy.

11. The system of claim 1, further comprising a pushbutton that when selected receives data corresponding to information obtained after an analysis has been performed.

12. The system of claim 1, wherein at least one of the selectable input boxes indicates that a combination of tasks is appropriate for addressing the failure mode, and the logic is further configured to receive data indicative of a plurality of tasks associated with the combination of tasks.

13. The system of claim 1, wherein the logic is further configured to receive data indicative of an action item to be performed in association with the failure mode.

14. The system of claim 1, wherein the logic is further configured to receive data indicative of additional information that may be needed in order to further analyze the failure mode.

15. The system of claim 1, wherein the logic is further configured to receive data indicating that the failure mode is to be identified for an audit process.

17. The system of claim 1, wherein the logic is further configured to receive mode remark data indicative of additional information related to the failure mode.

18. The system of claim 1, wherein one of the selectable input boxes indicates that a human error may have been involved with the failure mode.

16. The system of claim 16, wherein the logic is further configured to receive data indicative of a date for the audit process, members of an audit team, or a date of an RCM analysis corresponding to the failure mode.

19. A reliability centered maintenance method, comprising:

receiving data indicative of a function, a functional failure, a failure mode, and a failure effect;

storing the data in memory;

displaying the data received in the receiving step to a display device in response to a first user input;

displaying a plurality of logical selectable input boxes corresponding to a type of the failure mode;

receiving data indicative of at least one task for addressing the failure mode;

receiving at least one selection input via the selectable input boxes;

receiving data describing the at least one task; and

storing in memory data indicative of the at least one task, the failure mode type, and the selection input for the failure mode.

20. The method of claim 19, further comprising displaying the data and the input boxes to the projection screen and the display device simultaneously.

21. The method of claim 20, enlarging the data displayed to the screen in response to a second user input.

22. The method of claim 19, further comprising displaying a portion of the plurality of selectable input boxes corresponding to hidden failure modes.

23. The method of claim 22, displaying the portion of the plurality of selectable input boxes corresponding to an on-condition task, a restoration task, a replacement task, an operational check, or a combination of tasks associated with the failure mode.

24. The method of claim 19, further comprising displaying a portion of the plurality of selectable input boxes corresponding to evident failure modes.

25. The method of claim 24, further comprising displaying the portion of the plurality of selectable input boxes corresponding to an on-condition task, a restoration task, a replacement task, an operation check, or a combination of tasks associated with the failure mode.

26. The method of claim 19, further comprising receiving, via the input device, data indicative of a time interval associated with performing the at least one task.
