Tolerance Design Optimization Model for Variation and Cost Reduction

摘要

This paper presetnes an optimization model of tolerance design for variations control and cost reduction. Reducing system variations can reduce the loss to the customer but it may lead to a higher cot tot he manufacture. On the other hand, larger tolerance limits or larger allowable variations can adversely affect product quality. To facilitate the task of tolerance design, we can establish a generic optimization model. The control variables in this model are the toelrance levels associated with the design parameters and process parameters. Our goal in design is to minimize the quality loss and the production cost by selecting the best level settings of the tolerance limits.
