关 键 词：Multiattribute decision-making Fuzzy method Relative significance factor 

摘      要：A relative significance factor of an impact category is the external weight of the impact category and plays an important role in life cycle assessment（LCA）.Many multiattribute decision-making （MADM） methods such as analytical hierarchy process（AHP）,the rank-order centroid method and the fuzzy method are proposed to determine the relative significance factor of an impact ***,in previous research,it is shown that,the AHP approach is difficult for experts rendering consistent judgment when the number of pairwise comparisons increases,the rank-order method has some insurmountable shortcomings,the key issue to use fuzzy set theory is its *** order to address this problem,a new simple and efficient method is proposed to determine relative significance factor in a more efficient *** example to determine relative significance factor of impact categories is shown to illustrate the efficiency of the proposed method.
