多属性群决策中权重自适应调整的方法

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

在已知专家和属性主观权重的基础上,提出了一种多属性群决策中权重自适应调整的方法。该方法根据专家个体决策与群体决策之间的偏离程度计算专家权重并用熵权系数法计算属性的权重,以新的权重重新计算出专家个体决策与群体决策,并以此对权重做进一步调整。重复以上步骤,直至计算出稳定的综合权重和决策结果。给出算例说明了该方法的可行性。

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.
