sensitivity analysis in the qualiflex and vikor methods

the sensitivity analysis for multi-attribute decision making (madm) problems is important for two reasons: first, the decision matrix as the source of the results of a decision problem is inaccurate because it sorts the alternatives in each criterion inaccurately. second, the decision maker may change his opinions in a time period because of changes in the importance of the criteria and in the policy of the organization over time. this in turn makes problem solving really time-consuming. therefore, the best solution is to do sensitivity analysis.in this regard, this paper considers a sensitivity analysis in the qualiflex method which is a compromise ranking method used for multi-criteria decision making (mcdm).
