Method of adaptive adjustment weights in multi-attribute group decision-making

Based on giving subjective weights of experts and attributes,an adaptive adjustment weights method in multi-attribute group decision-making with is proposed. This method employs entropy coefficient theories and compares the difference between individual decision results and the group's to adjust weights in order to get more reliable weights.Firstly,the initial decision results of individual experts can be got according to the subjective weights.Secondly,the new weights of experts and attributes can be calculated through comparing the difference between individual decision results and the group's.Finally,the above process will be repeated to get steadily weights.Numerical example shows that the adaptive method is feasibility.
