Rank reversal tools.
Rank reversal is a change in the preferred order of alternatives that occurs when the selection method or available options change. It is a significant issue in decision-making, particularly in multi-criteria decision-making.
One way to test the validity of decision-making methods is to construct special test problems and then study the solutions they derive. If the solutions exhibit some logic contradictions (in the form of undesirable rank reversals of the alternatives), then one may argue that something is wrong with the method that derived them.
The module offers features for automating the execution and assessment of standard tests for rank reversal, primarily focusing on alterations in the available options.
