For reducing environmental loads and resource consumption over the entire product life cycle without decreasing the product's value, life cycle design is a promised approach. Design of a product lifecycle involves planning lifecycle strategies, evaluating them from various viewpoints and optimizing the overall picture. Product lifecycle strategies can be planned explicitly by describing lifecycle scenarios at an early stage of lifecycle design and the product should be designed to realize the scenario. In this study, we developed a computer-aided design environment for lifecycle design called "Life-Cycle CAD" system. The system links a lifecycle model we defined with product architecture and manages the consistency between them. Case studies clarified that the relationship between the lifecycle model and the product model is successfully represented on a computer in an integrated manner to support product lifecycle design.
