Proposal of Quality Function Deployment Based on Multispace Design Model and its Application

Abstract

Due to the specialization and professionalization of the design work, sharing the product information between the product development members has been important in the product development process. Quality Function Deployment is one of the effective methods that enables the development members to share the information of the product using the quality matrices that describes the relationship between design elements needed to be considered. This paper improves the quality matrices by introducing the multispace design model and the Interpretive structural modeling. The proposed quality matrices are applied to a disc brake design problem, and their applicability is confirmed.
