Fuzzy Clustering of Multi-factors Evaluated System

We constitued a fuzzy similar matrix with characteristic function of samples of evaluated object,and computed transitive closure of fuzzy similar matrix.Accoding to transtive closure,different λ-cut of fuzzy set are clustered,and we may get rational classification result.With an example of evaluation of district econmic develop level,we present the steps and method of fuzzy clustering for multi-factors evaluated system.
