Abstract

A method for maintaining a complex article, including retrieving maintenance information relating to maintenance of a component of a complex article from an electronically-accessible tag coupled to the component and applying the retrieved maintenance information to a determination regarding maintenance of the complex article. A device including a complex article including a first component and a second component, the first and second components being one of individually replaceable and maintainable. The first component is tagged with a first tag that stores first computer accessible information including a first identifier identifying the first component and first maintenance information describing maintenance of the first component. The second component is tagged with a second tag that stores second computer accessible information including a second identifier identifying the second component and second maintenance information describing maintenance of the second component.

Claims

1. A method for performing maintenance for a complex article, comprising:

for one or more of a plurality of electronically-accessible tags that are each coupled to a respective component of the complex article, storing maintenance information about the respective component; and

for at least one of the plurality of electronically-accessible tags, storing at least a portion of the maintenance information that describes maintenance of the complex article as a whole.

2. The method of claim 1, further comprising:

for at least one of the plurality of electronically-accessible tags, storing at least a portion of information that describes technical and operational relationships of and between the components.

3. The method of claim 2, wherein storing information that describes technical and operational relationships of the components includes:

storing the information as a hierarchy in which each node represents a component and links represent the technical and operational relationships of the components.

4. The method of claim 2, further comprising:

storing, in the at least one of the plurality of electronically-accessible tags, information that identifies a particular component that has been removed from the article, that specifies whether the particular component has been replaced, and that specifies the geographical location of the particular component.

5. The method of claim 2, further comprising:

determining a priority of maintenance based on the technical and operational relationships of the components.

6. The method of claim 1, wherein storing maintenance information includes:

storing the maintenance information that describes maintenance of the article as a whole in a tag that is coupled to the complex article.

7. The method of claim 6, further comprising:

storing, in the tag, maintenance information as a hierarchy in which each node represents a component and links represent the technical and operational relationships of the components.

8. The method of claim 6, further comprising:

exchanging maintenance information between the tag and at least one of the plurality of electronically-accessible tags.

9. The method of claim 6, further comprising:

storing, in the tag, information describing the use of the article; and

determining which maintenance is to be performed based on the use of the complex article.

10. The method of claim 6, further comprising:

storing, in the tag, a list of all of the plurality of electronically-accessible tags.

11. The method of claim 1 wherein each of the plurality of electronically-accessible tags stores a portion of the maintenance information associated with the complex article.

12. The method of claim 1 wherein one of the plurality of electronically-accessible tags stores all of the maintenance information associated with the complex article.

13. A system for performing maintenance, comprising:

a plurality of electronically-accessible tags, each electronically-accessible tag being coupled to a respective component of an article, each electronically-accessible tag including maintenance information for the component to which the electronically-accessible tag is coupled, and at least one of the plurality of electronically-accessible tags including information that describes maintenance of the article as a whole.

14. The system of claim 13, wherein:

the at least one of the plurality of electronically-accessible tags includes information that describes technical and operational relationships of the components.

15. The system of claim 14, wherein:

information that describes technical and operational relationships of the components is stored as a hierarchy in which each node represents a component and links represent the technical and operational relationships of the components.

16. The system of claim 14, wherein:

the at least one of the plurality of electronically-accessible tags includes information that identifies a particular component that has been removed from the article, that specifies whether the particular component has been replaced, and that specifies the geographical location of the particular component.

17. The system of claim 14, further comprising:

a processor and logic for accessing information that describes technical and operational relationships of the components, and for determining a priority of maintenance based on the technical and operational relationships of the components.

18. The system of claim 13, further comprising:

a tag that is coupled to the article and that includes maintenance information that describes maintenance of the article as a whole.

19. The system of claim 16, wherein:

the tag includes maintenance information that describes a hierarchy in which each node represents a component and links represent the technical and operational relationships of the components.

20. The system of claim 13, further comprising:

an interrogator for reading and writing data to one or more of the electronically-accessible tags.

21. The system of claim 13, wherein:

the plurality of electronically-accessible tags are linked so that one electronically-accessible tag can exchange information with another electronically-accessible tag.

22. The system of claim 21, wherein:

the tag exchanges maintenance information with one of the plurality of electronically-accessible tags, and updates information that describes maintenance of the article as a whole.
