摘　　要：对属性值为区间数的多属性不确定性决策问题,先由区间数向量定义四组实数向量,然后利用实数状态变权向量和上述四组向量导出相应的区间数状态变权向量,由此得出区间数变权公式,进而建立区间数变权综合决策模型.最后给出一个应用区间数变权综合决策模型的实例.With respect to multiple attribute uncertain decision making in which the attribute values are intervals, four groups of real number vector are defined by applying of interval number vector. Then, state variable vector with intervals is induced by the state variable vector with real number and the above four groups of real number vector, and an interval variable weight formula is proposed. Simultaneously, a variable weight synthesis decision making model with intervals is established. Finally, an example is given to illustrate the validity of this decision making model.
