In machine product designs, a variety of characteristics such as product performances, manufacturing cost, and robustness of characteristics are evaluated, and the need for improvements is increasingly stringent over time. Such characteristics almost always have interrelationships, and systematic evaluation and optimization must be performed to obtain preferable product design solutions. To conduct effective system optimization, the complex interrelationships among characteristics that are included, and sometimes hidden, in the optimization problem, must be understood and dealt with. To construct optimization methodologies for such problems, these relationships must be clarified, and the characteristics simplified. Simplifying the characteristics makes the essence of the optimization problem clearer, and facilitates examining the interrelationships among the simplified characteristics during the optimization process. Based on the simplified characteristics, "priority relationships", i.e., relationships among simplified characteristics that will be optimized first, and "conflicting relationships", i.e., tradeoff relationships that will be simultaneously optimized, are obtained. Hierarchical optimization procedures develop naturally as the relationships among the simplified characteristics are clarified. This paper focuses on the priority relationships of characteristics in system optimization procedures. General and specific rules concerning priority relationships are presented, and these form the basis for the constructed optimization procedures. An applied example of a machine tool product design is presented to demonstrate the effectiveness of the proposed methodology.
