Abstract: Based on introduing the entropy of the weight sequence of grey clustering,the relation between a grey clustering analysis result and the entropy of the weight sequence is pointed out The measure method of the grey characteristics of a grey clustering analysis result is obtained with its properties The quantification for the charaterisitics of a grey clustering analysis result is able to help users deeply understand the results of grey clustering analysis the computing procedure and actual significance of the measure of the grey characteristics of a grey clustreing result are also explained

Key words: grey clustering, characteristics of a result, entropy, characteristic measure
