Análise da eficiência na geração de resíduos sólidos nos terminais de carga geral brasileiro utilizando DEA

Abstract

Based on the National Solid Waste Policy, the Brazilian port sector was forced to manage the waste generated in ports and port terminals. From the inventory of waste, it was possible to analyze the efficiency in the generation of waste in port terminals that predominantly handle the general cargo, using the Data Envelopment Analysis (DEA) method. The output-oriented DEA BCC model was adopted. In addition, this work used three analyzes, one general and two peer-to-peer. The result of the general analysis, in which the three variables were considered, presented eight efficient terminals, having one false-efficient terminal. The DMU 18 was the most efficient because it obtained the highest value in the Normalized Compound. In the peer-to-peer analysis, the efficient border was formed by only two DMU's, where the presence of DMU 21 is observed in the three analyzes. Moreover, in one of the peer-to-peer analyzes it was observed that the model attributed the highest value in the Normalized Compound to the DMU 20 that was not efficient. In this case, the composite and normalized composite indicators were disregarded from the analysis, using standard and inverted efficiency indicators. This article includes the identification of the terminals with the best and worst management practices.

Análise Da Eficiência Das Empresas De Cerâmica Vermelha Da Região Do Carajás-Pa

“…First stage (Literature review): following the postulates of Calvaignac; Petiot (2017), a descriptive and analytical evaluation of the literature was done, supported by qualitative and quantitative analyzes. In this literature reviewing process, there were selected the works developed by Giacomello;Oliveira (2013), Vasconcelos et al (2016), Garcia et al (2017) and Rabelo et al (CCR) and technical efficiency (BCC), although they are applied in different economic segments of the red ceramic industry such as hotels, academic units of a university and port terminals.…”

“…In this analysis, there are two classic models: the CCR or CRS (CHARNES et al, 1978;GARCIA et al, 2017), which takes into account the constant returns to scale, and the BCC or VRS model (BANKER et al, 1984), that considers variable returns scale, not assuming proportionality between inputs and outputs and assuming greater operational diversity (due to its more efficient units and different tradeoffs at the border) (LINS and CALÔBA, 2006). Both models allow free choice of the weights givens for the inputs and outputs of each DMU, which leads to the selection of the set of weights that maximize efficiency.…”
