Optimal Process Targeting of Multi-Components Multi-Characteristics Products

摘要

In this paper a process targeting model for multi-components multi-characteristic products is developed. The cost function is based on a multivariable Taguchi type quadratic loss function for product uniformity, and a quadratic term for the cost of components. Closed form expressions for the optimal process targets are derived. We provided an illustrative example, and discussed the effect of the weights in the quadratic cost on the tradeoffs between the product quality and the production cost. Further extension of the work is also discussed.
