Application of method of operational research (DEA) in the performance evaluation of production units for area vocational education

Abstract

The Data Envelopment Analysis (Data Envelopment Analysis - DEA) has been extensively used as management support, in estimating the relative performance of production units similar. Particularly has been applied to companies that work using multiple inputs to produce multiple products, for which it is difficult to assign prices or weights. The study is an exploratory, descriptive and evaluative. The techniques of data collection were observation, document analysis and literature review. The information collected is treated in a qualitative and quantitative. This paper presents a case study of applying this method to a nonprofit corporation, the area of professional education and technical and technological services (SENAI, the National Service of Industrial Learning). It studies the replacement of existing procedures for evaluating performance of production units, including operational aspects, financial and management. Assesses the performance of 21 operating units of SENAI two perspectives: financial and quality. The DEA model chosen is variable returns to scale -oriented product (CCB). The results show that 33.3% of the units are efficient in the financial perspective, 42.8% are from the perspective of quality, and 19, 0% of total units are effective from both perspectives. We conclude that the DEA model is appropriate for performance evaluation of the operational units of SENAI provides valuable results for the managers of the institution such as setting goals and identifying benchmarks for the inefficient units.
