摘　　要：基于区间数相离度理论和熵值理论,探讨了一类多阶段多属性三端点区间数型群决策中的动态属性权重、动态专家权重和阶段权重问题,提出了多阶段属性权重确定方法和阶段内专家权重的计算方法.计算出属性权重、阶段内专家权重和阶段权重,并利用区间数贴近度方法生成最终的群决策方案排序.应用实例分析结果表明,所提出的决策方法具有较好的可行性和合理性.The problems about dynamic weights of attributes and experts, and stage weight in multi-stage and multi- attributes group decision-making are discussed based on the theory about the distance degree of interval numbers and entropy values. It is described how to confirm the weights of multi-attributes, expert＇ weights in single stages and stage weight based on decision preference of stages, and then the ultima choice is given. A numerical example shows the feasibility and practicability of the proposed algorithm.
