Abstract

A manufacturing management device 100 includes an acquisition unit 121 that acquires unique information of a product from a captured image of the product captured in a manufacturing step included in a manufacturing process of the product, and acquires operation information representing an operation of a person who performs a manufacturing work on the product in the manufacturing step, and an association unit 122 that sores the acquired unique information of the product and the acquired operation information in association with each other.

First claim

What is claimed is:

1. A manufacturing management method comprising:
acquiring unique information of a product from a captured image of the product captured in a manufacturing step included in a manufacturing process of the product, and acquiring operation information representing an operation of a person who performs a manufacturing work on the product in the manufacturing step; and
storing the acquired unique information of the product and the acquired operation information in association with each other.

2. The manufacturing management method according to claim 1 , further comprising
when evaluating the product, acquiring the unique information of the product from the captured image of the product, and reading out the operation information stored in association with unique information that is identical to the acquired unique information.

3. The manufacturing management method according to claim 2 , further comprising
specifying a work operation of a person corresponding to the evaluation of the product, on the basis of the operation information that is read out when evaluating the product.

4. The manufacturing management method according to claim 3 , further comprising
specifying a correlation between a content of the evaluation of the product and the operation information, on a basis of the operation information that is read out when evaluating the product for each product having a different evaluation content.

5. The manufacturing management method according to claim 3 , further comprising
outputting operation assistance information for assisting a work operation of a person, on a basis of the evaluation of the product and the specified work operation of the person corresponding to the evaluation of the product.

6. The manufacturing management method according to claim 5 , further comprising
outputting the operation assistance information to the person who performs the manufacturing work on the product in the manufacturing step.

7. The manufacturing management method according to claim 5 , further comprising
acquiring, as the operation information, a person image obtained by capturing the person who performs the manufacturing work on the product in the manufacturing step, and
generating the operation assistance information on a basis of the person image and outputting the operation assistance information.

8. The manufacturing management method according to claim 7 , further comprising
on a basis of the person image, generating the operation assistance information including text information for supporting the work operation of the person, and outputting the operation assistance information.

9. The manufacturing management method according to claim 3 , further comprising
storing the evaluation of the product and the specified work operation of the person corresponding to the evaluation of the product, in association with each other; and
thereafter, acquiring the unique information of the product from the captured image of the product captured in the manufacturing step, acquiring the operation information of the person who performs the manufacturing work on the product in the manufacturing step, and determining the evaluation of the product stored in association with the work operation of the person corresponding to the acquired operation information, to be evaluation of quality of the product having the acquired unique information.

10. The manufacturing management method according to claim 1 , further comprising
acquiring the unique information of the product from a captured image of the product captured for each manufacturing step, and acquiring the operation information in the manufacturing step;
storing the unique information of the product and the operation information, acquired in an identical manufacturing step, in association with each other;
when evaluating the product, acquiring the unique information of the product from the captured image of the product, and reading out the operation information for each manufacturing step stored in association with unique information that is identical to the acquired unique information; and
specifying a work operation of a person corresponding to the evaluation of the product, on a basis of the readout operation information for each manufacturing step.

11. A manufacturing management device comprising:
at least one memory configured to store instructions; and
at least one processor configured to execute instructions to:
acquire unique information of a product from a captured image of the product captured in a manufacturing step included in a manufacturing process of the product, and acquire operation information representing an operation of a person who performs a manufacturing work on the product in the manufacturing step, and
store the acquired unique information of the product and the acquired operation information in association with each other.

12. The manufacturing management device according to claim 11 , wherein the at least one processor is configured to execute the instructions to
when evaluating the product, acquire the unique information of the product from the captured image of the product, and read out the operation information stored in association with unique information that is identical to the acquired unique information.

13. The manufacturing management device according to claim 12 , wherein the at least one processor is configured to execute the instructions to
specify a work operation of a person corresponding to the evaluation of the product, on a basis of the operation information that is read out when the product is evaluated.

14. The manufacturing management device according to claim 12 , wherein the at least one processor is configured to execute the instructions to
specify a correlation between a content of the evaluation of the product and the operation information, on a basis of the operation information that is read out when the product is evaluated for each product having a different evaluation content.

15. The manufacturing management device according to claim 13 , wherein the at least one processor is configured to execute the instructions to
store the evaluation of the product and the the specified work operation of the person corresponding to the evaluation of the product, in association with each other, and
thereafter, acquire the unique information of the product from the captured image of the product captured in the manufacturing step, acquire the operation information of the person who performs the manufacturing work on the product in the manufacturing step, and determine the evaluation of the product stored in association with the work operation of the person corresponding to the acquired operation information, to be evaluation of quality of the product having the acquired unique information.

16. The manufacturing management device according to claim 13 , wherein the at least one processor is configured to execute the instructions to
output operation assistance information for assisting a work operation of a person, on a basis of the evaluation of the product and the specified work operation of the person corresponding to the evaluation of the product.

17. The manufacturing management device according to claim 16 , wherein the at least one processor is configured to execute the instructions to
output the operation assistance information to the person who performs the manufacturing work on the product in the manufacturing step.

18. The manufacturing management device according to claim 16 , wherein the at least one processor is con
