The pattern of multi-objective and multi-dimensional grey-fuzzy decision with self feedback

The study on decision making is of important guide for theory and practice. Based on the theories of fuzzy recognition, the pattern of multiple objects and multiple dimensional grey-fuzzy decision making with self feedback is presented in this paper. Firstly, according to the given weights, weighting integrated value of decision making is computed. Secondly, the method of fuzzy recognition with single index is employed to calculate the fuzzy classification of the integrated value. At last, according to the cause analysis, the fuzzy classification of the integrated value is used to compute the cluster center and the weights of indexes. In a similar way, repeating the above processes, the weighting integrated value and fuzzy classification with given accuracy are gotten at the same time; the classification and sequence of decision making set are also gained. The example of steelmaking enterprise evaluation show that the model presented in this paper is valid.
