IEP : ferramenta para medição da eficiência produtiva em indústria frigorífica bovina.

Abstract

Considering its importance in the brazilian economy in recent times due to the heavy demands of the national and international markets, bovine fridge branch companies pursue excellence in productivity. In this respect, there is a clear need for these companies to adopt criteria and tools for measuring their production processes in order to assess their productivity. However, it is known the lack of knowledge of scientific equipment, as well as research work in this field, which could support the construction of measuring productivity for the industry due to the fact that these industries have recently dawned on the national economic scene. This paper, therefore, proposes the construction of a new indicator of productivity for businesses of bovine fridge branch, using multivariate analysis as the main tool (by the method of PCA - Principal Component Analysis) and taking as object of study the Frigorífico Silva Indústria e Comércio Ltda enterprise. First, a review of the current productivity indicator used by the company was performed established in Sectors Boning and Secondary Packaging: the kg-man-hour (currently contested by managers and experts of business processes) through the application of a questionnaire to sixteen people (all managers and/or experts of business processes). After this step, the process variables were defined to be measured, yielding a group of twenty-two variables to be observed for a period of sixty-three days, thus defining the array of data have been defined for the analysis. Through this, we applied the method of PCA to first identify and exclude variables with little statistical weight. Subsequently, we determined the statistical weights of the remaining variables, enabling the construction of productivity indices for each observation by applying a mathematical model, which IEP (Índice de Eficiência Produtiva - Productive Efficiency Ratio) were named. After obtaining the IEP for each observation, it was subjected to an evaluation process provided an indicator of industry productivity study object. It is concluded, through this procedure, that with the application and interpretation of the IEP was possible to describe more reliably the productive efficiency of the industry studied in relation to the kg-man-hour indicator used.
