Análise da eficiência técnica de uma empresa estadual de saneamento

Abstract

Through DEA methodology -Data Envelopment Analysis, which is based on mathematical programming procedures and allows the attainment of a nonparametric frontier of efficiency, this work has as main objective to propose a general indicator of technicalefficiency of a group of Cagece business units and identify its possibly determines. As a variable for this analysis, four inputs and five outputs were chosen. The research noticed the applicability of DEA methodology and was able to measure the general technical efficiency of thirteen business units, from the efficiency scores. An comparative analyze of technical efficiency of Cagece business units was presented, being possible to identify the most efficient ones that would be reaching the best level of transformation of their inputs into outputs, denoting their efficiency. In accordance with the research eight of this units were considered efficient and five of them inefficient. It was also observed that the technical inefficiency was more expressive thanthe inefficiency of scale.
