  The feature of our method different from other fuzzy grey relation method for
supermixed multiple attribute group decision-making is that all of the
subjective and objective weights are obtained by interval grey number and that
the group decisionmaking is performed based on the relative approach degree of
grey TOPSIS, the relative approach degree of grey incidence and the relative
membership degree of grey incidence using 4-dimensional Euclidean distance. The
weighted Borda method is used to obtain final rank by using the results of four
methods. An example shows the applicability of the proposed approach.
