基于语言评价信息的快速集结方法研究

Research on Alternatives Fast Aggregated Model Based on Linguistic Evaluation Information

针对具有语言评价信息的多指标群决策问题,研究了基于二元语义的快速集结方法。把各决策者的语言评价信息转化为二元语义矩阵;依据各决策者的判断偏好,提出方案属性权重求解的规划模型;通过集结和比较各决策者偏好和总体偏好的差异,提出决策者权重确定模型;定义决策者判断一致度及决策者偏差的查找算法,快速辨别偏差较大的决策者并对其提供偏好调整建议;文后例子将其应用于某危险品的救险应急方案的选择。

The alternatives fast aggregated approach of two-tuple linguistic information process is proposed in views of the linguistic evaluated information group decision-making. Firstly, the linguistic evaluated information is transformed to two-tuple linguistic comparison matrix. Then according to the definitions of two-tuple linguistic and the preferences of every policy-maker＇s comparison matrix, an approach of calculating the policy-makers＇ attribute weights is proposed using the linear programming model. Secondly, the policy-makers＇ weights can be obtained through aggregating and comparing the preference of every policymaker and the whole preference. Finally, the alternative raking can be aggregated and the interactive method can be used to the evaluation of dangerous goods transport risk management. Meanwhile, the consensus degree of policy-makers is defined and the deviation of policy-maker can be found quickly. The pref- erence deviation proposal is also provided.
