碩士 === 逢甲大學 === 工業工程學系 === 88 === There are three kinds of cost in a product life cycle time, including of tolerance cost, quality loss cost and failure cost.

Most of the literature on this subject assume that the process mean is equal to the target value, but it is incorrect for quality characteristic is as asymmetric loss to set process mean to be the target value. So we apply a gearbox assembly in our study. We assume that the assembly function is known and quality characteristic is as asymmetric loss.
