Abstract
In the early process of design where a conceptual design and a basic design are done, a structural model is often used by designers. On the other hand, in the late process of design where a detailed design is done, a mathematical model is often used by engineers. In the conventional studies, a design method that has an ability to support the building of both models has not been proposed. In this study, the Hierarchical Design Model proposed by Matsuoka was paid attention to. Firstly, the Hierarchical QFD that reflects the features of Hierarchical Design Model has been expanded into the method that has an ability to grasp clearly sidebar impacts by introducing ISM method into it. Secondly, a selection method of design factors necessary for building a mathematical model from the Hierarchical QFD has been proposed. Consequently, a design method that has an ability to support the building of both models has been proposed. Then the proposed design method has been applied to each of the driver and the passenger seat design. As a result, two different design solutions that properly considered each usage environment have been obtained, and the effectiveness of the proposed design method has been confirmed.

A Proposal of Design Method Based on Hierarchical Design Model and an Application for Automotive Seat Designs
In the early process of design where a conceptual design and a basic design are done, a structural model is often used by designers.

Firstly, the Hierarchical QFD that reflects the features of Hierarchical Design Model has been expanded into the method that has an ability to grasp clearly sidebar impacts by introducing ISM method into it.
