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
