Abstract

A manufacturing execution system for manufacturing a product is provided. The manufacturing execution system includes a manufacturing execution plan having a set of manufacturing steps to be executed for manufacturing the product, a planning component for determining a data collection plan of data to be collected during the execution of one of the manufacturing steps, a service interface for providing the data collection plan in response to a service request, and a database for storing data that has been collected in accordance with the determined data collection plan.

Claims

1. A manufacturing execution system comprising:

a manufacturing execution plan indicative of manufacturing steps to be executed for manufacturing a product,

a planning component for determining a context-specific data collection plan for data to be collected during execution of at least one of the manufacturing steps,

a service interface for providing the data collection plan in response to a service request,

a database for storing data that has been collected in accordance with a context-specific data collection plan; and

an analytical component for analytically processing the data stored in the database, the planning component being operable to determine a modified context-specific data collection plan depending on a result of the analytical processing,

wherein the modified context-specific data collection plan is provided in response to a subsequent service request relating to the same context as a previous service request that resulted in the modification of the context-specific data collection plan.

2. The manufacturing execution system of claim 1, the context-specific data collection plan being specified by a set of objects.

3. The manufacturing execution system of claim 1, the context-specific data collection plan being a predefined default data collection plan.

4. The manufacturing execution system of claim 1, the modified context-specific data collection plan being provided by replacing or modifying at least one of the objects of the set of objects.

5. The manufacturing execution system of claim 1, further comprising a storage component for storing a predefined criterion and an action related to the criterion, wherein the action is triggered if the predefined criterion is not met by the data.

6. The manufacturing execution system of claim 5, the action being a maintenance action for a manufacturing tool used for the manufacturing of the product.

7. The manufacturing execution system of claim 6, the service interface being adapted to send a maintenance request indicative of the action to a maintenance workflow manager.

8. The manufacturing execution system of claim 1, the service interface being adapted to be coupled to a communication network.

9. A method of operating a manufacturing execution system, the manufacturing execution system comprising a manufacturing execution plan indicative of manufacturing steps to be executed by manufacturing tools for manufacturing a product, the method comprising:

receiving a request for a context-specific data collection plan from at least one of the manufacturing too1s;

determining the context-specific data collection plan for data to be collected during execution of one of the manufacturing steps depending on the context of the one of the manufacturing steps;

sending the context-specific data collection plan to the at least one of the manufacturing tools in response to the request;

acquiring data in accordance with the data collection plan;

processing the acquired data to provide a result; and

determining a modified data collection plan depending on the result,

wherein the modified data collection plan is sent to a requester in response to a subsequent service request relating to the same context.

10. The method of claim 9, wherein the context-specific data collection plan is sent to the at least one of the manufacturing tools via an interface.

11. The method of claim 9, the context-specific data collection plan being a default data collection plan.

12. The method of claim 9, further comprising triggering an action that is assigned to a predefined criterion if the acquired data does not meet the predefined criterion.

13. The method of claim 12, the action being a maintenance action for maintenance of the one of the manufacturing tools.

14. The method of claim 9, wherein the data collection plan is provided as an extended markup language (XML) document.

15. The method of claim 9, wherein the product is selected from a group comprising semiconductor products, automotive products, pharmaceutical products, solar cells, electronic devices, hard discs, consumer electronics products, and integrated electronic circuits.

16. A computer program product comprising computer executable instructions for performing a method in accordance with claim 9.
