摘要
介绍了模糊层次聚类的基本方法与步骤。运用模糊层次对我国部分上市皮革企业的经营绩效进行了聚类。聚类过程中,采用环比评分法确定指标的权重,运用极大极小法构造模糊相似矩阵,通过统计量比较分析,确定了最佳分类数目。结果显示:方法通俗易懂,直观生动,客观准确。
The basic methods and steps of fuzzy hierarchical clustering were introduced.Fuzzy hierarchy was used to cluster the operational performance of some listed leather enterprises in China.In the process of clustering,the ring comparison scoring method was used to determine the weight of the index,the minimax method was used to construct the fuzzy similarity matrix,and the optimal number of classifications was determined through statistical comparison and analysis.The results showed that the method was easy to understand,intuitive and vivid,objective and accurate.
