To make up the limitations of existing intuitionistic fuzzy sets clustering, a new fuzzy C-means clustering algorithm (WIFCM) based on weighted intuitionistic fuzzy set was proposed. The concepts of equivalent classification object and weighted intuitionistic fuzzy set were put forward first, and based on which the objective function of WIFCM was derived. Iterative algorithms of clustering center and matrix of membership degree were inferred. It was proved that the cluster results were equivalent in dataset with two different cluster algorithms. And the WIFCM algorithm had better computational performance than the IFCM algorithm.
