“…3), as well as DMUs that presented inefficiency in the input-oriented CRS model. In this model the proportionality principle is applied and any variation in inputs implies the proportional variation of outputs (Tschaffon and Meza, 2014). In assessing the input-oriented CRS model standard efficiency in 2014 (Fig.…”

“…This can be very useful when we have few DMUs to analyze that almost all efficient and we need to have a benchmark, for instance, for regulation of public fares. Regulation of public fares using DEA was done in Thanassoulis et (2000), Tschaffon and Angulo-Meza (2014) and Andrade et al (2014), for instance.Therefore, the aim of this work was to determine the dual formulation for the MCDEA model, to study their properties and suggest benchmarks for the inefficient DMUs. To do so, we restrain ourselves to study the partial MCDEA model, i.e., models with only two objective functions.…”

In 1999, Li and Reeves presented the so-called MCDEA (Multiple Criteria Data Envelopment Analysis) model. This model is in fact a three objective linear model. It may be used to improve the discriminatory power of the DEA models, as well as generate a more reasonable distribution of the inputs and outputs weights. Besides the classical optimization of the efficiency index, Li and Reeves introduced two other objective functions, called minisum and minimax. Despite of being an important approach, it does not provide benchmarks or targets for inefficient DMUs. Benchmarks and targets are one of the most important DEA features and in standard DEA are determined using the dual (envelope) model. In this paper, we introduce an approach of the MCDEA dual formulation taking into account only two objective functions at each time. Combining both partial models we suggest benchmarks for each inefficient DMU.Keywords: Data Envelopment Analysis; Multi-objective; MCDEA; Duality; Benchmarks. IntroductionThe MultiCriteria Data Envelopment Analysis (MCDEA) model is classified by Climaco et al (2008) as a DEA model with additional objective functions and by Angulo-Meza and Lins (2002) as an increasing discrimination method with no a priori information from the decision maker. This model was proposed by Li and Reeves (1999), which takes into account two additional objective functions, called the minisum and minimax efficiency. This model was introduced to deal with two common problems in DEA models, poor discriminations among DMUs, and unreal distribution of inputs and outputs weights. However this model does not provide an efficiency index for all DMUs, nor targets and benchmarks. Some efficiency indexes based on the MCDEA model were obtained by Soares de Mello et al (2009) and used by Climaco et al (2010).A variation of the MCDEA was presented by Bal et al (2010). However, even these Maria Cecilia de Carvalho ChavesJoão Carlos C. B. Soares de Mello Lidia Angulo-MezaJournal of the Operational Research Society doi:10.1057/jors.2015.73 2 articles do not cover two important pieces of management information supplied by DEA models: the benchmarks and the targets for inefficient DMUs. In standard DEA, these targets and benchmarks are obtained using the envelopment model, which is in fact the dual formulation of the multiplier model. There are multiobjective DEA models that, despite not being able to provide efficiency indexes, provide benchmarks for the inefficient DMUS (Lins et al. 2004;Quariguasi Frota Neto and Angulo-Meza 2007).However, these models have a different structure than the Li and Reeve's model. This paper is in the same line of Gomes Jr et al (2013) which provides an efficiency index for models designed to determine benchmarks. Now, where are dealing with an inverse situation: we want to obtain benchmarks in a model designed to find efficiency indexes.In both situations, the aim is to obtain full information from models that originally provide only partial information.Therefore to determine benchmarks for inef...

“…In Tschaffon and Meza (2014) study, in which 20 Brazilian electricity distributors were analyzed in 2008, COELBA was the only company considered efficient and we identified COELBA as the company with the lowest efficiency score. Pinheiro (2012), when conducting an evaluation of Aneel's ranking (DGC-based ranking) for electricity distributors, found that efficient distributors generally present better performance in cost or quality.…”

Este artigo analisa a eficiência técnica relativa das empresas brasileiras distribuidoras de energia elétrica. A busca por eficiência tem sido constante em muitos setores e a indústria representa uma importante fonte de desenvolvimento econômico para o país. As distribuidoras de energia elétrica passaram por maiores transformações devido a transferência de controle acionário para empresas privadas. A pesquisa possui característica descritiva e abordagem quantitativa, utilizando como técnica de pesquisa a Análise Envoltória de Dados (DEA) realizada com base em dados de 2012. Identificou-se que apenas 1 em 17 distribuidoras de energia elétrica foram consideradas tecnicamente eficientes. As empresas COSERN e a RGE são os melhores benchmarks para as empresas ineficientes e são detentoras de diferentes prêmios de qualidade e gestão do setor. A variável que mais contribuiu para os escores de eficiência das empresas foi a variável Potência Instalada e as variáveis que necessitam de melhorias são o Desempenho Global de Continuidade e Tempo Médio de Atendimento.
