On the redistribution of existing inputs using the spherical frontier dea model

Abstract: The Spherical Frontier DEA Model (SFM) (Avellar et al., 2007) was developed to be used when one wants to fairly distribute a new and fixed input to a group of Decision Making Units (DMU's). SFM's basic idea is to distribute this new and fixed input in such a way that every DMU will be placed on an efficiency frontier with a spherical shape. We use SFM to analyze the problems that appear when one wants to redistribute an already existing input to a group of DMU's such that the total sum of this input will remai… Show more

“…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. 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.…”

“…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).…”
