pref-erence of Cone Constraints, when some of the outputs are undesirable, was discussed.
The output levels of a DMU are estimated when some or all of related input components are
increased and the current e ciency level is improved. To estimate the output levels, the
inverse data envelopment anal-ysis (DEA) and multi objective linear programming (MOLP)
models were used. The e cacy of the proposed method is indicated by using an application …
