Based on the subjective weights of experts, a new method for determining the objective weights is proposed. The method simultaneously takes the order difference and the data difference of the alternatives as the similarity index of measuring the individuals and group, and the order difference’s existence is prior to determine whether the data difference takes part in the calculation. Based on the similarity index, a new similarity function is defined to determine the objective weights of experts. Finally an example shows that the method is feasible.
