Study on grey synthetic clusters appraisals model

The grey cluster method, developed by Prof. Deng, makes use of the critical values of whitenization weighting function to compute the weights of indices, but the weights are affected seriously by the quantity unit level of samples, at the same time, there is no practiced meaning if the units of samples are different. In this paper, first deals with a new grey cluster analysis method based on the present methods and develop a new grey synthetic clusters appraisals model to solve the above question. Then, the idiographic process is presented. Last, we illustrate this method with an example, which is to select the domination industries of the second industry of Jiangsu province.
