PROJECT TITLE :
Estimating the Process Yield of Multiple Characteristics With One-Sided Specifications
This paper proposes a procedure for estimating the process yield of multiple characteristics with one-sided specifications in a manufacturing process. The proposed process yield indices can be applied for a multivariate normality data or a multivariate non-normality data. These indices provide an exact measure of the overall process yield. Also, the approximate lower confidence bound for the true process yield is presented. Three examples are used to demonstrate the performance of the proposed approach. The results show that our procedure is an effective approach.
