Abstract: Problems in agglomerative hierarchical clustering method are preseated when  Euclid or Minkowski distance is the distance measure,and the causes for those problems are explored.Accordingly,an improved agglomerative hierarchical clustering algorithm according to the idea of fuzzy clustring is put forward.The reasonability and validity of this improved algorithm are proved through an example.
