ABSTRACT:
The invention is a manufacturing process improvement method operative in the presence of random process fluctuations with allowance made for intervention by operating personnel. The method involves following a decision tree based on a number of heuristics. The effects of all process variables are evaluated in a phase in which each variable is perturbed separately to identify small, if any, effects on process responses. A sequence of phases progresses toward improved operating conditions. Reliance on small effects avoids severe process disruptions and leads to the incorporation of favorable variable interactions. Replications of variable perturbations and statistical analysis are used to identify small effects that coexist with random process fluctuations.
