Descrição

Congresso organizado pela Efiusco, realizado em Córdoba de 19-20 de Maio de 2011 Weights restriction is a well-known technique in the DEA field. 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.
