| 摘 要： | 权重是用来衡量多属性决策问题中各属性相对重要性的,它在很大程度上影响决策问题的求解结果。在区间数的"期望方差"排序法基础上,基于加权模型,对区间数多属性决策中权重灵敏度进行分析,并给出了当两个方案之间排序位置颠倒时某一指标的权重最小变化量的计算方法。最后给出了一个算例。

| Abstract: | The sensitivity to weight in multiple attribute decision making problem with intervals is analyzed. Based on the additive weighting model and the expectation and square difference method for priorities, the calculating method for minimum changes of weight is obtained when the ranking position between two alternatives is reversed. Finally, a numerical example is presented. |
