ملخص المقالة :
we discuss about the determination of the output levels of a decision-making units with the preference of cone constraints when some of the outputs are undesirable. The output levels of a DMU is estimated when some or all of its input components are increased and its current efficiency level is improved. To estimate the output levels, the inverse data envelopment analysis (DEA) and multi objective linear programming models are used.
