“…The regression problem described above is completely analogous to the problem of allocating a new input using DEA models such as the ones proposed by Beasley (2003), Avellar et al (2007), Guedes et al (2008) and Milioni et al (2008). In each one of them, allocating a new total fi xed input is the result of different methods with different degrees of complexity sharing, however, two basic features: (i) the fi nal result is expressed as percentages of the new total fi xed input that should be allocated to each DMU and (ii) just as in the regression problem, the total value and even the meaning of this new total fi xed input are irrelevant to the solution of the problem.…”

“…According to the model he proposed, the allocation of a new input should be such that, at the end, all DMU's should be effi cient (or at least technically effi cient). The same assumption was adopted by Gomes and Estellita Lins (2008), Avellar et al (2007), Guedes et al (2008) andMilioni et al (2008), who worked, in the last 3 cases, with the so called parametric DEA formulation, characterized by the fact that the effi ciency frontier obeys a specifi c and predefi ned locus of points.…”

“…Milioni, de Avellar, Rabello, and De Freitas (2011b) further extended the Avellar et al (2007) approach from input resource allocation to output target setting, and the authors studied both new fixed output setting and existing output resetting. Guedes, Milioni, de Avellar, and Silva (2012) proposed a new adjusted spherical frontier DEA model for input allocation, which has an important feature called coherence, implying that the generated allocation plan will be relatively stable and will not change with a small data modification. Milioni, de Avellar, and Gomest al.…”

“…Embora em um contexto totalmente diferente (o da distribuição de recursos e/ou produtos), os chamados modelos DEA paramétricos também apresentam uma fronteira eficiente continuamente diferenciável. Estes modelos podem ser vistos em Milioni & Alves (2013), Guedes et al (2012), , Milioni et al (2011a, b), Avellar et al (2010), Colen et al (2009), Avellar et al (2007, e Silveira et al (2011).…”
