When those techniques are applied, weights cluster around its new limits, making its evaluation dependent of its levels. This paper introduces a new approach to weights adjustment by Goal Programming techniques, avoiding the imposition of hard restrictions that can even lead to unfeasibility. This method results in models that are more flexible.engLinear ProgrammingEfficiencyGoal ProgrammingWeights RestrictionData Envelopment AnalysisOptimizationconference object2014-03-13
