Abstract

Techniques for distributed production control include tagging unfinished products with electronically accessible production information that identifies aspects in which the products are to be produced differently. The production information is used to control an aspect of the production of a given product.

Claims

1. A method for producing a customized product comprising:

receiving an unfinished product tagged with a first tag comprising first electronically accessible production information that identifies an aspect of finishing the unfinished product;

receiving an unfinished component of the product, the unfinished component tagged with a second tag comprising second electronically accessible production information that identifies an aspect of finishing the unfinished component;

using the first production information in performing at least a portion of finishing the unfinished product; and

using the second production information in performing at least a portion of finishing the unfinished component of the unfinished product.

2. The method of claim 1, wherein the first tag comprises production information that identifies the unfinished component of the unfinished product.

3. The method of claim 1, wherein the first tag comprises production information that identifies a process to be applied during finishing the unfinished product.

4. The method of claim 3, wherein the production information that identifies the process comprises production information that identifies a manner in which the process is to be applied.

5. The method of claim 1, wherein the second tag comprises production information that identifies a subcomponent of the unfinished component.

6. The method of claim 1, wherein the second tag comprises production information that identifies a process to be applied during finishing the unfinished component.

7. The method of claim 1, wherein the second tag comprises production information that identifies how the unfinished component is to be applied to the unfinished product.

8. The method of claim 1, wherein using the first production information comprises using the first production information to identify a manufacturing resource usable in performing finishing the unfinished product.

9. The method of claim 1, further comprising updating the first production information to reflect performance of the aspect of finishing the unfinished product.

10. The method of claim 1, wherein using the first production information comprises:

identifying that a second component specified in the first production information is unavailable; and

interrupting finishing the unfinished product based on unavailability of the second component.

11. A method for producing a customized product comprising:

receiving an unfinished product comprising a second component, the unfinished product tagged with a first tag comprising first electronically accessible production information that identifies an aspect of finishing the unfinished product, the second component tagged with a second tag comprising second electronically accessible production information that identifies an aspect of finishing the second component;

using the first production information in incorporating a first component into the unfinished product, wherein incorporation of the first component partially completes assembly of the unfinished product;

using the second production information in performing at least a portion of finishing the second component; and

before attempting to complete assembly of the product, updating the first tag to reflect the incorporation of the first component into the product and updating the second tag to reflect the portion of finishing the second component.

12. The method of claim 11, wherein updating the second tag comprises updating the second tag to reflect an application of a process to the second component.

13. The method of claim 11, wherein updating the second tag comprises updating the second tag with at least one of a production condition, as-built information, or an identifier of a production resource tool.

14. The method of claim 11, further comprising associating the first tag with the unfinished product.

15. The method of claim 11, further comprising verifying that finishing the second component has been performed in accordance with the second production information.

16. An article comprising:

an unfinished product comprising an unfinished component,

wherein the unfinished product is tagged with a first tag comprising first electronically accessible production information that identifies an aspect of finishing the unfinished product, the first production information comprising

component information identifying a component to be applied to the unfinished product,

process information, identifying a process to be applied to the unfinished product,

resource information identifying a manufacturing resource usable to perform at least a portion of finishing the unfinished product, and

updated information written at an assembly site, the updated information reflecting an incorporation of the component into the unfinished product before assembly of the unfinished product is completed, and

wherein the unfinished component is tagged with a second tag comprising second electronically accessible production information that identifies an aspect of finishing the unfinished component.

17. The article of claim 16, wherein the first production information further comprises condition information identifying a manner in which the process is to be applied to the unfinished product.

18. The article of claim 16, wherein the first production information further comprises at least one of a production condition, as-built information, or an identifier of a production resource tool.

19. The article of claim 16, wherein the component information comprises information identifying a characteristic of a part to be incorporated into the unfinished product.

20. The article of claim 16, wherein the first tag comprises a radio-frequency identification tag tagging the unfinished product.

21. The article of claim 16, wherein the updated information also reflects a performance of a process in the finishing of the unfinished product.

22. The article of claim 16, wherein the unfinished product further comprises a third component tagged with third electronically accessible production information.

23. The article of claim 22, wherein the third production information comprises information identifying an aspect of finishing the third component.

24. The article of claim 23, wherein the third production information comprises subcomponent information identifying a subcomponent of the third component.

25. The article of claim 23, wherein the third production information comprises second process information identifying a second process to be applied to the third component.

26. The article of claim 23, wherein the third production information comprises second resource information identifying a second manufacturing resource usable to perform the aspect of finishing the third component.
