Attribute Relative Sensitivity Analysis Based on Grey Relational Degree

This paper is concerned with the attribute relative sensitivity analysis based on grey relational degree (GRD).Now, a new method is proposed which is based on comparison of GRD ranking each other, which is on different attributes sets. This method does not need complex calculate, only request to calculate GRD ranking and the down sets of each elements. In the paper, we also study the properties of the algorithm. At last, an example about sensitivity analysis of the judgment of the urban traffic congestion shows this method is simple and effective on sensitivity analysis of grey relational analysis.
