方案排序对属性值的敏感性分析

多属性决策问题的属性值是决定方案排序的基础。由于许多主观和客观的原因 ,多属性决策问题中属性值的确定常常受到不确定、不精确和易变的因素影响 ,而这些因素将直接影响到决策的结果。从属性值最小变化量出发 ,结合实际案例研究了属性值变化对方案排序的影响及其量化方法 ,采用该方法可以确定出每一个方案对属性值改变的敏感性以及最敏感的方案。

The Sensitivity Analysis of Attribute Values Associated with the Ranking of Alternatives

Attribute values in multiattribute decision-making are the base of the alternatives' ranking. Because of many subjective and objective reasons, the determining of attribute values are often affected by uncertain, imprecise and inconstant factors, that can influence the decision-making result directly. In this paper, based on the minimum relative variables of attribute values, how the variety of attribute values affect the alternatives' ranking was discussed, and a quantitative express method was introduced with a numeral example. By this method, the sensitivity of each alternative can be determined and the most critical alternative can be found.
