| Summary: | 碩士 === 國立交通大學 === 工業工程與管理系 === 88 === In most products, the quality response with quantitative feature is frequently considered owing to the inherent nature of quality response. Conventional experimental designs and Taguchi method are two techniques. Taguchi method has been widely implemented in industry due to its simplexity. Most of the quantitative quality response in a state system. However, in some cases, the desired quality response may be a qualitative(or ordered categorical) type quality response and optimization of a qualitative quality response has seldom been mentioned in the literature. In addition, optimzing a dynamic system has received more attentions in recent years due to the increasing complexity of the product design. Hence, optimizing the ordered categorical response in a dynamic system becomes an
important issue in improving the product/process.
