Abstract:
Due to rise of environmental awareness in recent years, companies are required to assess and reduce environmental burdens of their products. However, in practical product development, since not only environmental burdens but also product characteristics such as performance and cost need to be simultaneously considered for creating attractive products, designers are forced to take a great deal of time and effort to balance them at a higher level at every stage of product development. In response to this, this paper proposes an integrated method for optimizing product design concept and product lifecycle scenario for supporting conceptual design phase. The proposed method combines integrated optimization of functional / layout design which we developed in the previous researches and lifecycle assessment (LCA). Using the proposed method, optimal functional structure, components / parts layout and lifecycle scenario that balance product characteristics and environmental burdens at a high
er level can be obtained.
