A Desirability Function Approach to the Robust Design for Multiple Quality Characteristics

호감도함수 접근법을 이용한 다수품질특성치의 강건설계

We often have multiple quality characteristics to develop, improve and optimize industrial processes and products. It is not easy to find optimal control factor setting when there are multiple quality characteristics, since there will be conflict among the selected levels of the control factors for each individual quality characteristic. In this paper we propose a desirability function approach and devise a scheme which gives a systematic way of solving multiple quality characteristic problems. A numerical example is provided.
