Análise das eficiências dos Ecopontos da Cidade de Fortaleza no Ceará pelo Modelo DEA SBM orientado a output

Abstract

This research was carried out to analyze the efficiency of the Ecopoints of the city of Fortaleza, in the state of Ceará, using the Data Envelopment Analysis (DEA) model that uses the Slacks-Based Measure (SBR) method oriented to output (products) with variable scales (SBM- O- V). The Decision Making Unit (DMUs) of the model are twenty-five Ecopoints, where there are two incentive collection programs, the “Recicla Fortaleza” and “E-carroceiro”. The inputs of the model are the production of construction waste (rubbish), cutting and pruning vegetation, bulky waste (useless as old furniture, refrigerator and others), OGR (oil and fat in general), recyclable waste with the outputs from the revenues from bonuses in reais (R$) of OGR and recyclable waste. The efficiencies found by the SBR-O-V model of classical and inverted boundaries are transformed into composite efficiencies and these into standardized ones. A scaling of standardized efficiencies from least efficient to most efficient is demonstrated. The scheduling analysis indicates the least efficient Ecopoints and which management attitudes should be taken seeking a maximization of production with the minimization of bonuses.
