Abstract
People who are not familiar with the multicriteria optimization theory often deal with multicriteria problems in the following way. One objective is taken as a single criteria to be optimized and some limits are set for the values of the other objectives. That is, the other objectives are treated as constraints in an ordinary optimization problem. After the optimization, a trade-off analysis may be carried out with respect to the active constraints. That is, the level of an active constraint — the limit of an objective — is changed a little and the optimization is done again to see how much the level of the optimized objective will change.
