| 摘 要： | 权重是用来衡量多属性决策问题各属性间的相对重要性的，它在很大程度上影响着多目标决策问题的求解结果，在主客观综合赋权方法的基础上，通过改变主，客观权重在综合权重中所占的比例，研究了这种比例的改变对方安排序的影响，提出了一种方案排序对权重的敏感性分析方法，通过实例讨论了在主观权重的基础上，增加多少客观权重，才能改变由主观权重所确定的方案排序。

| Abstract: | On the basis of the integrated weighting approach, the influence of the ranking results associated with this change was studied by changing the proportion of both subjective and objective weight. A sensitivity analysis method for the alterenatives' ranking results associated with the change of weight proportion was proposed. An example was given to illustrate the approach proposed. |
