Aplicação da análise envoltória de dados (AED) na avaliação da eficiência operacional relativa entre usinas de cana-de-açúcar no território brasileiro

Abstract: RESUMO:Este estudo tem por objetivo analisar o impacto das variáveis tamanho e localização na eficiência operacional de usinas de cana-de-açúcar no Brasil na safra 2008/2009. Para tanto, realizou-se um estudo de eficiência operacional, por meio da aplicação da Análise Envoltória de Dados (AED), na qual foi possível identificar as usinas mais eficientes dentre um universo de 355 e classificá-las por tamanho e localização. A análise quantitativa sugere que existe maior concentração de usinas classificadas como e… Show more

“…This result emphasizes the importance of crop production from these regions to the agriculture of the state. Just as found by Salgado Junior et al (2014) in their work on sugar mill efficiency, variables associated with geographical in the present case altitude, have an impact on the efficiency of the agriculture. Looking more deeply into the production data for the efficient municipalities, it becomes apparent that following the strategy emphasized by Nodari and Guerra (2015), in which productive diversity is promoted as the means to increasing agricultural efficiency, is indeed the basis of the most efficient DMUs.…”

“…Salgado Júnior assures that the plants' efficiency also depends on the variable "localization". For example, São Paulo state presents the edaphoclimatic conditions more favorable to the extraction of a cane with a higher tenor of saccharose, which, consequently, may influence the operational efficiency of sugarcane plants [12]. In Figure 1, we compare the variance of TRS yields of the crops from 2002/03 to 2014/15 by state.…”

“…Entretanto, para a realização dessa atividade econômica fundamental -a produção, são gerados efluentes e resíduos (ROSSETTI, 2016;SALGADO JUNIOR et al, 2014). O termo glicerol é um resíduo da produção de biodiesel e designa a produção de glicerina bruta (ANP, 2016).…”
