Abstract

A health monitoring system for a vehicle system includes an operational support system including a plurality of managers and a decision support module. Each manager corresponds to a different sub-system of the vehicle system, and comprises a plurality of reasoners and a fusion block. Each reasoner is configured to obtain data and provide preliminary output regarding a different component of the sub-system based on the data. The fusion block is coupled to the plurality of reasoners, and is configured to receive the preliminary output and generating manager output based on the preliminary output. The decision support module is coupled to the plurality of managers, and is configured to receive the manager output and provide a decision support output based on the manager output.

Claims

1. A program product for performing diagnostics on a vehicle system, the program product comprising:

a program configured to at least facilitate performing the diagnostics on the vehicle system, the program comprising;

a plurality of managers, each of the plurality of managers corresponding to a different sub-system of the vehicle system, each of the plurality of managers comprising;

a plurality of reasoners, each of the plurality of reasoners configured to at least facilitate obtaining data and providing preliminary output regarding a different component of the sub-system based at least in part on the data; and

a fusion block coupled to the plurality of reasoners, the fusion block configured to at least facilitate receiving the preliminary output and generating manager output based at least in part on the preliminary output, wherein the fusion block is configured to at least facilitate conducting fusion block analysis based at least in part on the preliminary output and generating the manager output based at least in part on the fusion block analysis; and

a decision support module coupled to the plurality of managers, the decision support module configured to at least facilitate;

receiving the manager output from the plurality of managers; and

providing a decision support output based at least in part on the manager output, wherein the decision support module is configured to at least facilitate performing decision support analysis based at least in part on the manager output and generating the decision support output based at least in part on the decision support analysis; and

a computer-readable signal-bearing media bearing the program.

2. The program product of claim 1, wherein:

each of the plurality of reasoners is further configured to at least facilitate conducting reasoner analysis based at least in part on the data; and

the preliminary output is based at least in part on the reasoner analysis.

3. The program product of claim 1, wherein:

the program further comprises a plurality of enterprises, each of the plurality of enterprises configured to generate an enterprise output; and

the decision support module is further configured to at least facilitate;

receiving the enterprise output from at least one of the plurality of enterprises; and

performing the decision support analysis also based at least in part on the enterprise output.

4. The program product of claim 3, wherein the program further comprises:

an enterprise service bus coupled to the plurality of enterprises and the decision support module and configured to at least facilitate flow of the enterprise output to the decision support module and to receive the decision support output from the decision support module; and

a plurality of interfaces coupled to the enterprise service bus, the decision support module, and the plurality of enterprises and configured to at least facilitate flow of the decision support output to the enterprise service bus and flow of the enterprise output to the decision support module.

5. The program product of claim 4, wherein the program further comprises:

a diagnostic network coupled to the enterprise service bus and configured to receive the decision support output therefrom; and

a presentation layer coupled to the diagnostic network and configured to receive the decision support output therefrom.

6. A computer system for performing diagnostics on a vehicle system, the computer system comprising:

a processor;

a memory coupled to the processor; and

a program residing in the memory and configured to be executed by the processor, the program configured to at least facilitate performing the diagnostics on the vehicle system, the program comprising;

a plurality of managers, each of the plurality of managers corresponding to a different sub-system of the vehicle system, each of the plurality of managers comprising;

a plurality of reasoners, each of the plurality of reasoners configured to at least facilitate obtaining data and providing preliminary output regarding a different component of the sub-system based at least in part on the data; and

a fusion block coupled to the plurality of reasoners, the fusion block configured to at least facilitate receiving the preliminary output and generating manager output based at least in part on the preliminary output; and

a decision support module coupled to the plurality of managers, the decision support module configured to at least facilitate;

receiving the manager output from the plurality of managers; and

providing a decision support output based at least in part on the manager output.

7. The computer system of claim 6, wherein:

each of the plurality of reasoners is further configured to at least facilitate conducting reasoner analysis based at least in part on the data; and

the preliminary output is based at least in part on the reasoner analysis.

8. The computer system of claim 7, wherein:

the fusion block is configured to at least facilitate conducting fusion block analysis based at least in part on the preliminary output and generating the manager output based at least in part on the fusion block analysis; and

the decision support module is configured to at least facilitate performing decision support analysis based at least in part on the manager output and generating the decision support output based at least in part on the decision support analysis.

9. The computer system of claim 8, wherein:

the program further comprises a plurality of enterprises, each of the plurality of enterprises configured to generate an enterprise output; and

the decision support module is further configured to at least facilitate;

receiving the enterprise output from at least one of the plurality of enterprises; and

performing the decision support analysis also based at least in part on the enterprise output.

10. The computer system of claim 9, wherein the program further comprises:

an enterprise service bus coupled to the plurality of enterprises and the decision support module and configured to at least facilitate flow of the enterprise output to the decision support module and to receive the decision support output from the decision support module; and

a plurality of interfaces coupled to the enterprise service bus, the decision support module, and the plurality of enterprises and configured to at least facilitate flow of the decision support output to the enterprise service bus and flow of the enterprise output to the decision support module.

11. The computer system of claim 10, wherein the program further comprises:

a diagnostic network coupled to the enterprise service bus and configured to receive the decision support output therefrom; and

a presentation layer coupled to the diagnostic network and configured to receive the decision support output therefrom.
