摘要
指标权重系数的确定是综合评价中的一个关键问题.针对工程机械综合评价中权重系数的确定问题,利用模糊数判断矩阵、Friedman一致性检验和Spearman等级相关系数对主客观赋权法进行组合,提出一种适合于工程机械综合评价的组合赋权法.最后通过工程实例验证了该方法的合理性.
The indices weighting secures a crucial position in multi-criteria evaluation.Specifically for construction machinery,such techniques as the fuzzy number judgment matrix,Friedman consistency examination,and Spearman reciprocal ranking coefficient are combined to weight subjective and objective indices.In this manner, a new combinatory weighting method is developed for multi-criteria evaluation. Finally,industrial cases are applied to validate the feasibility of this approach.
