Abstract:

There are some problems in determining the index weight in the model of grey clustering for interval grey numbers. According to the definition of entropy, the method of grey entropyweight is proposed to determine the index weight, thus the corresponding algorithm is conducted. In the grey clustering model based on the entropy and interval grey numbers, the index weight is given by calculating the grey entropy on the basis of the grey numbers’ information. Finally, a practical example is presented and studied. The results show the better distinction degree of the normalized matrix with clustering coefficients, which can illustrate the effectiveness and the practicality of the proposed model.
