Abstract: Geomagnetic map suitability evaluation involves a large number of properties. It is meaningful to analyze the change of attribute weights which can impact on evaluation results. It has abstracted multiple attribute decision making problem from the geomagnetic map suitability evaluation. Firstly, the common geomagnetic map attributes and the weighted sum model used for alternatives ranking are given. Secondly, the change scope of weights are researched when maintained the order result unchanged. Thirdly, sensitivity analysis is performed when the changes of attribute weights and the change intervals are deduced by quantitative analysis. Finally, combining with an instance, the change scope of weights and the most sensitivity attribute are obtained, which provide a reference for decision makers.

Key words: sensitivity analysis, multiple attribute decision making, reversed, suitability
