“…For these studies, the efficiency frontier is supposed to have a specific hyperbolic shape. Avellar, Milioni, and Rabello (2007) made the first attempt to allocate a new fixed input across DMUs by considering a spherical frontier. Interestingly, Avellar et al (2007) obtained a straightforward formula to calculate the resource amount for each DMU, and all DMUs will be finally efficient.…”

“…Avellar, Milioni, and Rabello (2007) made the first attempt to allocate a new fixed input across DMUs by considering a spherical frontier. Interestingly, Avellar et al (2007) obtained a straightforward formula to calculate the resource amount for each DMU, and all DMUs will be finally efficient. Then Avellar, Milioni, Rabello, and Simão (2010) extended the same approach to another case where an already existing input resource will be reallocated across a set of DMUs.…”

“…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).…”

“…The issue of interpendence among DMUs when searching for targets is also treated by Lozano and Villa (2004) and Avellar et al (2006). However, ZSG-DEA models bring more interesting and simpler results, and treats both CCR and BCC models.…”

“…However, ZSG-DEA models bring more interesting and simpler results, and treats both CCR and BCC models. Additionally, our approach neither imposes any functional form to the efficient frontier (as the one of Avellar et al (2006), which is valid only for CCR), nor needs the efficiency maximization of each DMU simultaneously to the minimization of total resources or maximization of total production (as the approach of Lozano and Villa (2004), valid for BCC model). Our model needs only the calculation of DEA scores followed by the solution of a single equation.…”
