An integrated environmental and cost assessment method based on LCA and LCC for automobile interior and exterior trim design scheme optimization

摘要: This paper provided an integrated method to evaluate environmental impact and life cycle cost (LCC) of various alternative design schemes in the early development stages complex mechanical product; optimization product based on assessment (LCA) LCC is proposed as a supporting tool achieve optimal integration design. The applied research methods include level deconstruction model, LCA/LCC analysis scheme method. In assessment, GaBi software CML2001 evaluation are used impact. terms configuration optimization, TOPSIS optimize generated. Taking internal external trim automobile example, specific implementation process illustrated. case study indicates that, when comprehensively considering cost, composite indices worst 0.8667 0.3001, respectively; their costs ¥164.87 ¥179.68, eco points 14.74 39.78, respectively. two not much different, but only 37.1% scheme’s; When factor be considered, lowest about 36.7% maximum scheme’s 1.6 times scheme’s. least accounts 31.7% largest; with for 58.1% largest one’s. Integrating LCA LCC, scientific suggestions can from several perspectives. By this proposes which could options identify preferred option stage It helpful realize sustainability product. order improve applicability method, weighting factors adjusted according requirements energy saving emission reduction different enterprises.
