Abstract: Product life cycle design has gained increasing interest in recent years due to growing concerns about environmental problems. In general, there exist significant uncertainties (e.g., operating conditions, user preference, post-consumer product collection rate, etc.) in the product life cycle, requiring a design method that is robust and tolerant against these uncertainties. To this end, this paper discusses design strategies for products and their life cycle to enhance total performance as a defence measure. Based on the discussion, a robust design method is proposed for maximising environmental and economic performance for the product life cycle. The effectiveness and feasibility of this method are demonstrated through a simple example of laptop computers.
