RESUMO

Today, more and more companies undertak a search for unbridled productive efficiency in its operations being that, this efficiency will be vital to the survival of these companies in an increasingly competitive market. With this, made it necessary to the development of techniques that help in the analysis and evaluation of the productive efficiency of firms. These techniques, known generally how techniques of the productive efficiencys analysis, are divided into two categories: (a) the parametric (which build a function) and (b) the non-parametric (which perform calculations empirical through a border of efficiency) being that, among the non-parametric techniques for the analysis of efficiency, we can cite the data envelopment analysis (DEA) and the technique of index numbers. The main objective of this work is to identify the main non-parametric techniques of productive efficiency´s analysis existing in the literature and discover its main dimensions, models, equations, perspectives and updates, and then compare them, seeing in which situations each technique responds better. For this, a review was undertaken of the main concepts related to these techniques and built a system specialist that systematize the process of choosing among the various techniques, models and prospective of productive efficiencys analysis found. With this work expect itself to get a compilation of the main techniques nonparametric of analysis of efficiency that existing in the literature, which can help managers and academics who will come to study or perhaps refine these techniques.
