摘　　要：建立了基于生命周期影响评价的车用替代燃料多目标优化模型,以车用替代燃料生命周期影响总水平值为优化目标,并以木薯乙醇为例,对车用替代燃料进行了多目标优化。结果表明,多目标优化后木薯乙醇生命周期影响总水平值降低44.7%,建议木薯乙醇在汽油中的混合比例为95%,在乙醇生产过程中使用天然气燃料。A multi-objective optimization model of automotive alternative fuels based on its life cycle impact assessment was established in this paper, using the overall environment impact value （OEIV） as the optimization objeetive. And, multi-objective optimization of cassava-based ethanol was done as a ease study. The multi-objective optimization results shown that OEIV could be reduced about 44. 7%, the blend ratio of cassava-based ethanol into gasoline should be 95%, and the processing fuel during ethanol conversion stage should be natural gas.
