Then two approaches to multiple attribute decision making with intuitionistic fuzzy preference information are proposed. 通过求解这些模型获得属性的权重，进而给出了一种基于直觉模糊偏好信息的多属性决策途径。
In order to reflect the decision makers' subjective preference information, an optimization model is constructed to assess the attribute weights and rank the alternatives. 通过构造优化模型，反映决策者对方案的主观偏好信息，求出属性权重向量，从而对方案进行排序。
