“…We assume unitary input for all experimental units to make the analysis consistent. This idea is not unusual in the DEA literature and can be seen, for instance, in Caporaletti et al (1999), Lovell andPastor (1999), De Koeijer et al (2002), Leta et al (2005), and Gomes et al (2008Gomes et al ( , 2012.…”

-This study aimed to assess the physical performance of Pantaneiro horses with and without equine infectious anemia (EIA) under functional conditions of cattle management. The horses were subjected to a performance test and split into two groups according to a completely randomized design: animals were chosen from populations testing positive and negative for EIA. Performance was measured as a function of a data envelopment analysis (DEA) model considering four outputs and one unitary input. The output measures were the distance achieved in the performance test, hematocrit as a weighted average over the test duration, respiratory rate as weighted average over the test duration, and the level of lactic acid at the test termination. Weights for the hematocrit and the respiratory rate output variables were determined by means of factor analysis. The performance score was a weighted average of the output variables with the weights defined by the averages of the optimum individual multipliers in the DEA analysis. Contextual variables of interest were age, horse weight, room temperature, and corporal temperature. Only groups and room temperature were statistically significant effects, as indicated by a bootstrap analysis. The performance of group positive for EIA is significantly lower than that of the group negative for EIA and room temperature has a negative effect.

“…O input unitário é adotado para evitar as inconsistências matemáticas de um modelo sem inputs (Lovell e Pastor, 1999). Caporaletti et al (1999) interpretam a ausência de inputs como um modelo multiatributo. De fato, esse tipo de modelo DEA é equivalente a um modelo multicritério aditivo em que as alternativas (DMUs) atribuem os pesos a cada critério (outputs), ignorando qualquer juízo de valor de um eventual decisor.…”

RESUMOO objetivo deste trabalho é avaliar as eficiências produtivas de pequenos lotes destinados à agricultura familiar. Para tanto, será usada uma abordagem que combina Mapas AutoOrganizáveis e Análise Envoltória de Dados, com a finalidade de agrupar as unidades produtivas em clusters de similaridade, para, então, avaliar suas respectivas eficiências dentro do grupo correspondente. Os lotes pertencem ao Projeto Agricultura Familiar em Faixa de Dutos, que representa uma estratégia de ocupação agrícola para a faixa de terra sobrejacente aos dutos da refinaria da Petrobras, que atravessam o município de Nova Iguaçu-RJ. Os dados referem-se à produção mensal de 2012, destinada à comercialização em feiras livres e abrangem a quantidade de itens oferecidos, volume e preço médio de cada produto. Os resultados indicam que as eficiências acompanham os níveis dos elementos químicos observados no solo dos lotes. Palavras-chave: Análise Envoltória de Dados; Eficiência; Mapas Auto-Organizáveis. Área Principal: DEA -Análise Envoltória de Dados. ABSTRACTThe aim of this study is to evaluate the productive efficiencies of small plots, intended for family agriculture. For this purpose, we use an approach which combines Self-Organizing Maps and Data Envelopment Analysis models, to cluster the production units, and then evaluate their efficiencies within the group. The plots belong to a project called "Projeto Agricultura Familiar em Faixa de Dutos", which is a strategy for agricultural use and occupation for the strip of land overlying the Petrobras refinery pipelines that cross the municipality of Nova Iguaçu-RJ. The data refer to the 2012 monthly production of each plot intended for trade fairs in market-places and include the quantity of items offered, volume and average price of each product. The results indicate that the efficiencies follow the level of chemical elements observed in the soil.

“…In this regard we follow Caporaletti, Dulá, and Womer (1999) who show how to incorporate variance into the DEA framework. In their approach, measures of uncertainty (the variance of construction cost for example) are regarded as additional attributes to be priced along with the others.…”

Benefit-cost analysis using data envelopment analysis

et al. 2006

Benefit-cost analysis is required by law and regulation throughout the federal government. Robert Dorfman (1996) declares "Three prominent shortcomings of benefit-cost analysis as currently practiced are (1) it does not identify the population segments that the proposed measure benefits or harms (2) it attempts to reduce all comparisons to a single dimension, generally dollars and cents and (3) it conceals the degree of inaccuracy or uncertainty in its estimates." The paper develops an approach for conducting benefit-cost analysis derived from data envelopment analysis (DEA) that overcomes each of Dorfman's objections. The models and methodology proposed give decision makers a tool for evaluating alternative policies and projects where there are multiple constituencies who may have conflicting perspectives. This method incorporates multiple incommensurate attributes while allowing for measures of uncertainty. An application is used to illustrate the method.
