摘要: 灵敏度分析是多属性决策的一个重要优化过程,深入分析属性值或属性权重的变化对决策结果的影响很有意义。在线性加权模型的基础上,提出一种灵敏度分析方法,研究了一个属性值或者多个相关属性值同时发生变动以及一个属性权重或者多个相关属性权重同时发生变动下的灵敏度问题,给出一种定量化计算方法,计算出保持原决策排序结果不变的属性及属性权重的灵敏度临界值或稳定区间。通过某小口径火炮供弹机实例验证了该方法的科学性和可行性,计算结果可为供弹机优化设计提供参考。

Abstract: Sensitivity analysis is an important optimization process of multi-attribute decision making, of which thorough analysis of attribute values or change of attribute weights makes great sense in making decision. On the basis of the linear weighting model, a sensitivity analysis method is proposed, the sensitivity problem which is caused by the change of an attribute value or more related attribute values and the change of an attribute weight or more related attribute weights is researched, and the critical value or the stable interval of sensitivity which keeps the original sort result of decision unchangeable are calculated by a quantitative calculation method. The example about some small-bore artillery feed mechanism shows that the method is scientific and feasible.

Key words: system engineering methodology, multi-attribute decision making, attribute value, attribute weight, sensitivity analysis, feed mechanism
