A Integrated Methodology for Product Life Cycle Design

With the increasing public environmental consciousness, chemical product design requires simultaneous satisfaction and compromise of environmental and economic performance. To fulfill the two conflicting while complementary objectives, a systematic approach for life cycle design of chemical product is proposed in this paper. Multi-attribute decision-making is adopted in a trade-off consideration of both technical-economical evaluation and environment impacts assessment with the analytic hierarchy process approach. Based on the evaluation of relative importance of criteria, multi-criteria decision making is performed.
