On the optimal design centering,tolerancing, and tuning problem

In this note, we point out an erroneous result appearing in the literature on the optimal design centering, tolerancing, and tuning problem. Using the same framework of outer approximations, we then suggest alternate approaches to the solution of this problem, including a special-purpose subalgorithm.This research was supported by the National Science Foundation, Grant No. ECS-82-04452.
