摘要
[目的]对确权方法进行比较及稳定性分析。[方法]利用熵权法、相关分析法、主成分分析法对指标进行赋权,并利用稳定检测方法对权数进行稳定性检测。[结果]主成分分析法在一致性和稳定性方面表现最优。[结论]该研究为烤烟化学成分赋权提供了参考依据。
[Objective] To compare and analyze the stability of several weight-deciding methods.[Method] The entropy method,correlation coefficient method and principal component analysis were used to decide the index weight,and then the stability of weights was determined.[Result] The principal component analysis method performed the best in both its consistency and stability.[Conclusion] The study provided references for the weight-deciding of tobacco chemical components.
