[Abstract]

　To reduce the environmental burden such as green house effect gas and waste, caused by industrial products, ecologically conscious design, or design with life cycle analysis will be potential option, and play an important role. Results of design activities may dominate a products' burden in lower stream of processes such as production, use, and disposal. Attention should be paid to a fact that concurrent engineering is promising to optimize total environmental burden by solving trade-off relations among various estimation factors which naturally tend to conflict each other. In this paper, a concept of environmentally conscious design strategy is presented, and a design support system with analysis and evaluation capability for environmental burden is discussed.
　A prototype design support system has been developed as software framework. This support system is based on customizing technique for a CAD system and communication technique between different processes. An early-stage design process of material selection for a car body is demonstrated by solving the formulated relation between weight reduction and strength as an example. This design process is guided by an investigated and proposed design strategy which is based on finding and resolving trade-off problem in various criteria. Preliminary structural design process has been also incorporated into the developed system.
