Abstract

A recursive mapping structure for diagnostic models is provided. A parent diagnostic model includes a first input module, a first output module, a first monitor module coupled to the first input and first output modules, and a first propagation module coupled between the first input and first output modules. A child diagnostic model includes a second input module, a second output module, a second monitor module coupled to the second input and second output modules, and a second propagation module coupled between the second input and second output modules, wherein the second monitor module is coupled to the first monitor module.

Claims

1. A recursive mapping structure for diagnostic models interpreted by at least one diagnostic reasoner, comprising:

a parent diagnostic model, including;

a first input module,

a first output module,

a first monitor module coupled to the first input and first output modules, and

a first propagation module coupled between the first input and first output modules; and

a child diagnostic model, including;

a second input module,

a second output module,

a second monitor module coupled to the second input and second output modules, and

a second propagation module coupled between the second input and second output modules, wherein the second monitor module is coupled to the first monitor module.

2. The recursive mapping structure of claim 1, wherein the child diagnostic model is representative of a line-replaceable unit (LRU).

3. The recursive mapping structure of claim 1, wherein the parent and child diagnostic models are incorporated into a database schema.

4. The recursive mapping structure of claim 1, further including an additional child diagnostic model having an additional second input module, wherein the second output module is coupled to the additional second input module.

5. The recursive mapping structure of claim 4, wherein the child diagnostic model and the additional child diagnostic model are incorporated into a system reference model defined by the parent diagnostic model.

6. The recursive mapping structure of claim 5, wherein the system reference model is representative of a system.

7. The recursive mapping structure of claim 4, further including a grandparent diagnostic model having a third monitor module, wherein the first monitor module is coupled to the third monitor module.

8. The recursive mapping structure of claim 7, further including an additional parent diagnostic model having an additional first input module, wherein the first output module is coupled to the additional first input module.

9. The recursive mapping structure of claim 8, wherein the parent diagnostic model and the additional parent diagnostic model are incorporated into a platform reference model defined by the grandparent diagnostic model.

10. The recursive mapping structure of claim 9, wherein the platform reference model is representative of a platform.

11. A reference diagnostic model having a recursive mapping structure, the diagnostic model interpreted by at least one diagnostic reasoner comprising:

an input module;

an output module;

a propagation module in communication with the input and output modules, the propagation module adapted to describe at least one corrective action; and

a monitor module in communication with the input and output modules, wherein the input and output module are adapted for communication with an additional reference model on a single level of a hierarchy.

12. The reference model of claim 11, wherein the single level is a line-replaceable unit (LRU) level, system level, or platform level.

13. The reference model of claim 11, wherein the monitor module is adapted for communication with an additional reference model on an additional level.

14. The reference model of claim 13, wherein the single level is a line-replaceable unit (LRU) level, and the additional level is a system level.

15. A computer program product for implementing a plurality of diagnostic models having a recursive mapping structure, the plurality of diagnostic models interpreted by at least one diagnostic reasoner, the computer program product comprising a computer-readable storage medium having computer-readable program portions stored therein, the computer-readable program code portions comprising:

a first data file portion implementing a parent diagnostic model, including;

a first input module,

a first output module,

a first monitor module logically coupled to the first input and first output modules, and

a first propagation module logically coupled between the first input and first output modules; and

a second data file portion implementing a child diagnostic model, including;

a second input module,

a second output module,

a second monitor module logically coupled to the second input and second output modules, and

a second propagation module logically coupled between the second input and second output modules, wherein the second monitor module is logically coupled to the first monitor module.

16. The computer program product of claim 15, wherein the child diagnostic model is representative of a line-replaceable unit (LRU).

17. The computer program product of claim 15, wherein the parent and child diagnostic models are incorporated into a database schema.

18. The computer program product of claim 15, wherein the second data file portion implements an additional child diagnostic model having an additional second input module, wherein the second output module is logically coupled to the additional second input module.

19. The computer program product of claim 18, wherein the child diagnostic model and the additional child diagnostic model are incorporated into a system reference model defined by the parent diagnostic model.

20. The computer program product of claim 19, wherein the system reference model is representative of a system.
