摘要
DSS公司《Expert Choice》软件中的敏感度分析以图形方式给出了方案排序权值随一个准则权值的改变而变化的情况,当该准则的权值给定之后,其它准则的权值也按某种规律被确定下来。本文给出了根据对这些图形的分析得出的计算这些准则的权值的公式,并导出了为得到这个新的权向量在关于这些准则的判断矩阵中应做的改变,解释了这些改变的含义。此外也讨论了改变准则的权向量对一致性比例的影响以及使用这种敏感度分析方法应注意的问题。
The sensitivity utility in DSS software 'Expert Choice' is used to see how sensitive the priorities for the alternatives are to changes in the importance (i. e. priority) of a criterion. When the priority for the criterion is given, the priorities for other criteria will be determined by some rule. This paper gives the rule——the formula for calculating the priorities of these criteria, and it deduces the change that should occur in the judgment ma- trix on the criteria for getting the priority vector. The paper discusses, too, the effect of the priority vector on the inconsistency ratio as well as some aspects worth of note when adopting the method.
