Abstract

A method for assisting a user in selecting a design of experiment. The method includes obtaining a plurality of attributes associated with a plurality of experimental designs. A series of questions is presented to the user directed to objectives of the design of experiment. The user responds to the questions and one or more user-selected attributes are determined in response to the user'"'"'s answers to the questions. The process selects or de-selects one or more of the experimental designs in response to the user-selected attributes and notifies the user of the selected experimental designs.

Claims

1. A method for assisting a user in selecting at least one experimental design comprising:

obtaining a plurality of attributes associated with a plurality of experimental designs;

presenting a series of questions to the user directed to objectives of said experimental designs;

determining one or more user-selected attributes in response to the user'"'"'s answers to said questions;

selecting or deselecting at least one of said plurality of experimental designs in response to said user-selected attributes; and

notifying the user of the selected at least one experimental design,

wherein one of said questions is directed to whether the user is using a minimum number of runs.

2. The method for assisting a user of claim 1 wherein:

one of said questions is directed to whether the user is screening.

3. The method for assisting a user of claim 1 wherein:

said experimental designs include factors; and

one of said questions is directed to interactions between factors.

4. The method for assisting a user of claim 3 wherein:

one of said questions is directed to the number of interactions between factors to be tracked.

5. The method for assisting a user of claim 1 wherein:

one of said questions is directed to selection of one of a first and second order response surface.

6. The method for assisting a user of claim 1 wherein:

one of said questions is directed to whether certain design conditions are unfeasible.

7. The method for assisting a user of claim 4 wherein:

one of said questions is directed to the number of levels assigned to one of the factors.

8. The method for assisting a user of claim 1 wherein:

one of said questions is directed to a shape of a design space.

9. The method for assisting a user of claim 1 wherein:

one of said questions is directed to a location in the design space having high accuracy.

10. A storage medium encoded with machine-readable computer program code for causing a computer to implement a method of:

obtaining a plurality of attributes associated with a plurality of experimental designs;

presenting a series of questions to the user directed to objectives of said experimental designs;

determining one or more user-selected attributes in response to the user'"'"'s answers to said questions;

selecting or deselecting at least one of said plurality of experimental designs in response to said user-selected attributes; and

notifying the user of the selected at least one experimental design,

wherein one of said questions is directed to whether the user is using a minimum number of runs.

11. The storage medium of claim 10 wherein:

one of said questions is directed to whether the user is screening.

12. The storage medium of claim 10 wherein:

said experimental designs include factors; and

one of said questions is directed to interactions between factors.

13. The storage medium of claim 12 wherein:

one of said questions is directed to the number of interactions between factors are to be tracked.

14. The storage medium of claim 10 wherein:

one of said questions is directed to selection of one of a first and second order response surface.

15. The storage medium of claim 10 wherein:

one of said questions is directed to whether certain design conditions are unfeasible.

16. The storage medium of claim 12 wherein:

one of said questions is directed to the number of levels assigned to one of the factors.

17. The storage medium of claim 10 wherein:

one of said questions is directed to a shape of a design space.

18. The storage medium of claim 10 wherein:

one of said questions is directed to a location in the design space having high accuracy.
