function, and makes the determination of weighting factor complicated. Therefore the valuation of LCIA profile is the most critical and controversial step in life cycle assessment(LCA). Development... weighting factors becomes very difficult and complicated for society or a group of stakeholders. The valuation model of LCIA profile is involved in social, political and ethical value choice[11]. Different......
