多属性决策中基于加权模型的属性值灵敏度分析

The Sensitivity Analysis to Attribute Values Based on the Additive Weighting Model in Multiple Attribute Decision Making

针对多属性决策中属性值的灵敏度分析 ,首先介绍了方案灵敏度及最灵敏方案等有关概念 ;然后在考虑将比重变换法作为属性值规范化方法的情况下 ,基于加权模型 ,给出了当两个方案之间排序位置颠倒时某一属性值的最小变化量的计算方法 ,并且在此基础上 ,可找出最灵敏方案·最后给出了一个算例·

With respect to the sensitivity analysis to attribute values in multiple attribute decision making problems, firstly, the concepts on the criticality degree of alternative and the most critical alternative were introduced. Then, based on a normalizing approach to attribute values and the additive weighting model, minimum changes of attribute values by which the ranking positions between two alternatives will be reversed were obtained, and the most critical alternative can be found by the obtained minimum changes of attribute values. Finally, a numerical example was presented.
