Notes

The profile curve is not recalculated automatically when distributions change. Click Rerun to update the curve.

Defect Profiling does not address the general optimization problem of optimizing quality against cost, given functions that represent all aspects of the problem. This more general problem would benefit from a surrogate model and space filling design.

The defect profiles tend to be uneven when they are low. This is due, in part, to the use of the cubic scale where differences in low values are exaggerated. Jagged defect profiles could be due to limited simulation runs. If the overall defect curve (black line) is smooth, and the individual defect rates are fairly consistent, then your simulation probably has enough runs to provide a stable solution. If the overall defect rate curve is jagged, then consider increasing the number of runs. 20,000 runs is generally enough to stabilize the curves.
