Then, the weighted comprehensive clustering coefficient vector was calculated based on the group of weight vector with kernel.

At last, a novel two-stage decision model based on the group of weight vector with kernel and the weighted comprehensive clustering coefficient vector is put forward to solve the dilemma in grey clustering evaluation.
