Details	Preplanning the life cycle options for each part of a product and evaluating the environmental loads of the product at the early phase of design by applying 3D-CAD lead to resource recycling and significant reductions in the environmental loads for the whole product life cycle. The early phase of design contains multiple sources of uncertainties. This paper proposes a life cycle design support system based on 3D-CAD, which enables a sat-isficing design for both the product performances and the reduction of the environmental loads. The proposed system supports to define the life cycle options and to obtain multi-satisfactory design solution sets by apply-ing a preference set-based design method, which enables a flexible and robust design under various sources of uncertainties. The present study applies the proposed system to a multi-objective problem for technical and environmental performance requirements as an example problem, that is, a cleaner model created by 3D-CAD.
