Abstract :
Grey cluster is one of the most important models of Grey system. But most the methods of grey cluster can not rank the objects, and try to classify them to an accurate grey class. Then the result of grey cluster loses its “greyness”. Grey Cluster Integration Coefficient is created to solve the ranking problem, and Hierarchical Cluster is used to improve grey cluster to make the result more reasonable.
